The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 2. Conventions The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, NOT RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in RFC 2119 [RFC2119]. 3. Overview This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes a set of managed objects to configure and monitor Small Computer System Interface entities (SCSI entities), i.e. SCSI Devices, SCSI Targets and Initiators and SCSI Ports. SCSI is a client-server protocol in which application clients within an initiator device (client) issue service requests to logical units contained in a target (server). Hallak-Stamler et al. Expires March 2003 [Page 3] SCSI MIB September 2003 This MIB is based on documents defined by the ANSI T10 Technical Committee, specifically the SCSI Architecture Model - 2 document [SAM-2]. 3.1 Introduction In the late 1970s a firm called Shugart Associates started to have some considerable success with a peripheral interface definition in what became the PC marketplace, and this interface was adopted and extended by an open standards committee to form the Small Computer Systems Interface (SCSI). SCSI defines an 8 bit wide multi- drop "bus" structure which could interconnect a total of eight peripherals and computer systems. It's important to realize that all SCSI initially standardized was the "physical connection" i.e. the connectors, cables and interface signals. Thus even though a peripheral could be connected to multiple systems, the information that flowed across the interface was different in each case. This was addressed some five years later by the definition of a Common Command Set, and with this definition in place it was possible for the first time to develop a peripheral with both a common interface and common operating firmware for connection to multiple systems. The physical interface of SCSI continued to be developed throughout the 1980s with the addition of fast (up to 10 megabytes/s) and wide (16 bits) variants, but the distance supported remained a maximum of 25 meters (from one end of the bus to another), and indeed some of the faster variants supported much less than that distance. The command set development continued, with special commands for tapes, printers, and even processors being added to the original disk- oriented set. So successful was SCSI in the 1980s that the majority of the available Operating Systems incorporated support for the SCSI command set as standard. However at the end of the 1980s the distance, speed and number of devices supported by SCSI were starting to become significant impediments to systems design, and while the "information explosion" had not yet started in earnest, it was already being anticipated. At the same time, the serial interface technologies developed for Local Area Networks such as Ethernet, and the fibre optics technologies that were first deployed in telecommunications applications, were starting to appear sufficiently rugged & low-cost for use in peripheral interface applications. Thus a standards project was begun in 1988 to develop a new serial, fibre-optic interface to carry the SCSI command sets and other peripheral protocols. This interface eventually became known as Fibre Channel (FC), and it is based on an architecture centered around an abstractly defined "fabric", which Hallak-Stamler et al. Expires March 2003 [Page 4] SCSI MIB September 2003 may be a switch or a loop connection. MIBs for various FC equipments are already in existence. In order to support the new interfaces, it was necessary to completely reorganize the SCSI standards and definitions. The command sets were separated from the physical interface definitions, and a SCSI Architectural Model (SAM) was created to define the interaction between the various standards. It is a key to understanding SAM to realize that it was first created approximately 10 years AFTER the first SCSI products were shipped!! The most recent development in this saga occurred in 2000 when an IETF Working Group was formed to address, amongst other things, a definition for transporting the SCSI command sets directly over a TCP/IP infrastructure. This effort is known as iSCSI [IDISCSI20], and an iSCSI MIB is already under development [IDISCSIMIB09]. Most of the projects are in T10, except Fibre Channel that is defined by T11 and IEEE defines 1394. The SCSI MIB represents the SCSI protocol layer common to all SCSI command sets and transports. It does not represent the command sets and transports themselves. These should appear in other MIBs specific to the transport or command set. The following drawing shows the relationships between the various actual and possible SCSI-related MIBs. +---------------------------------+ SCSI Command | Higher-level MIBs, specific to | Sets | command sets, disk, tape, etc. | +---------------------------------+ SCSI | SCSI MIB | +-------+---------+-------+-------+ SCSI | iSCSI | FCP | SPI | Other | Transport | MIB | MIB | MIB | MIBs | Protocols | | | | | +-------+---------+-------+-------+ SCSI | TCP | Fibre | Other | Interconnect | MIB | Channel | Interconnect | | | MIBs | MIBs | +-------+---------+-------+-------+ An iSCSI MIB [IDISCSIMIB09], and a Fibre Channel interconnect MIB [IDFCMIB04] are currently being developed. No development is currently planned for standard command-set-specific or device- specific MIBs. Hallak-Stamler et al. Expires March 2003 [Page 5] SCSI MIB September 2003 Standard Fibre Channel interconnect MIBs [IDFCMIB04] are also under development. The TCP MIB [RFC2012] is already a proposed standard RFC 2012. 3.2 SCSI Terminology The following sections explain some of the SCSI terminology, which is used later in defining the MIB. For the authoritative definitions of these terms, see SAM-2 [SAM-2]. 3.2.1 SCSI Application Layer The protocols and procedures that implement or invoke SCSI commands and task management functions by using services provided by a SCSI protocol layer. 3.2.2 SCSI Device A SCSI device is an entity that contains one or more SCSI ports that are connected to a service delivery subsystem and supports a SCSI application protocol. 3.2.3 SCSI Port A SCSI port is a device-resident entity that connects the application client, device server or task manager to the service delivery subsystem through which requests and responses are routed. A SCSI port is synonymous with port and either a SCSI initiator port or a SCSI target port. 3.2.4 SCSI Initiator A SCSI initiator device contains application clients and SCSI initiator ports that originate device service and task management requests to be processed by a target SCSI device. When used this term refers to SCSI initiator devices or SCSI target/initiator devices that are using the SCSI target/initiator port as a SCSI initiator port. 3.2.5 SCSI Initiator Port A SCSI initiator port acts as the connection between application clients and the service delivery subsystem through which requests and responses are routed. In all cases when this term is used it refers to an initiator port or a SCSI target/initiator port operating as a SCSI initiator port. 3.2.6 SCSI Target Device A SCSI target device contains logical units and SCSI target ports that receive device service and task management requests for processing. When used this term refers to SCSI target devices or SCSI Hallak-Stamler et al. Expires March 2003 [Page 6] SCSI MIB September 2003 target/initiator devices that are using the SCSI target/initiator port as a SCSI target port. 3.2.7 SCSI Target Port A SCSI target port contains a task router and acts as the connection between device servers and task managers and the service delivery subsystem through which requests and responses are routed. When this term is used it refers to a SCSI target port or a SCSI target/initiator port operating as a SCSI target port. 3.2.8 Logical Units A logical unit is an entity residing in the target that implements a device model and processes SCSI commands sent by an application client. 3.2.9 Logical Unit Number A Logical Unit Number or LUN is a 64-bit identifier for a logical unit. 3.2.10 Interconnect Subsystem An interconnect subsystem is one or more physical interconnects that appear as a single path for the transfer of information between SCSI devices. 3.2.11 Device Server A device server is an object within the logical unit that processes SCSI tasks according to the rules for task management. 3.2.12 Task Manager A task manager is a server within the target that processes task management functions. 3.2.13 SCSI Instance A "SCSI instance" is a distinct SCSI entity within a managed system. While most implementations will have just one SCSI instance, the MIB allows for multiple (virtual) instances, such that a large system can be "partitioned" into multiple, distinct virtual systems. For example, in a host, it allows multiple vendors' implementations of the MIB to co-exist under a single SNMP agent through each vendor's implementation being a different SCSI instance. It also allows a single SNMP agent to represent multiple subsystems each of which have their own SCSI instance. 3.3 SCSI MIB Implementation The SCSI MIB is a basic building block to use in the various SCSI management scenarios. The SCSI MIB is intended to be implemented in every SCSI entity in a managed system. A SCSI entity can be a SCSI Hallak-Stamler et al. Expires March 2003 [Page 7] SCSI MIB September 2003 Initiator device, SCSI Target device or SCSI Initiator and Target device. Since SCSI (storage) networking devices may contain more than one SCSI entity, it is possible that more than one SCSI instance will reside in a single device. In small-scale environments a single network management station (NMS) may have SNMP access to both initiators and targets. However if the SCSI targets, or virtualized targets, are being provided as a service, it is more likely that the provider of the service owns and manages the targets, and that the consumer of the service owns and manages the initiators. In this case, the service provider NMS and the consumer NMS may have only allowed SNMP access to the targets and the initiators respectively. The figures in this chapter describe the location of the SCSI MIB implementations in the various SCSI management scenarios. The locations of the SCSI SNMP agent implementing the SCSI MIB, are denoted with '*. +----------+ +---------+ |SCSI | SCSI Transport |SCSI | |Initiator +---------------------------------------+Target | |Device | |Device | | * | | * | +----------+ +---------+ | | | | | | | | | | | SNMP +----------+ SNMP | +------------------|SCSI |-------------------+ |Management| | (NMS) | +----------+ Figure 1: Single SCSI Initiator device and Single SCSI Target device Figure 1 describes a simple SCSI management scenario of a SCSI Initiator device, a SCSI Target device and a Management station. In this scenario there are two SNMP agents, each containing its SCSI instance and its respective objects. As the SCSI Target and SCSI Initiator device are interconnected, their Target and Initiator port objects will be complementary. +-----------+ | +--------+-+ SCSI Transport +---------+ Hallak-Stamler et al.

In this case, the SCSI Target device's MIB will show that two SCSI Initiator devices are attached to it. +-----------+ +-----------+ | +----------+ +---------------+ +-+-------+ | | |SCSI |--------------| Virtualization| | SCSI | | |* |Initiator +--------------| Device +-------+ Target | | +--|Device | SCSI | | | Device | * | | | * | | * | | * |---+ | +----------+ Transport +------------+--+ +---------+ | | | | | | | | | | | | | | | | | | | | | | | | | | | | SNMP +-----------+ | SNMP | | +-------+------------------+ SCSI + +-+------------+-------+ | Management| | (NMS) | +-----------+ Figure 3: Multiple Hosts, Virtualization device and multiple Targets Figure 3 adds an in-band virtualization device which encapsulates, and possibly modifies, the SCSI Target devices representation to the SCSI Initiator devices. It is common practice for an in-band Hallak-Stamler et al. Expires March 2003 [Page 9] SCSI MIB September 2003 virtualization device, to include both SCSI Target and Initiator device functionality. Therefore, its SCSI MIB implementation includes both the SCSI Target and Initiator device objects. It should be noted that the Virtualization device may implement additional proprietary MIBs, as the SCSI MIB does not distinguish between physical and virtual SCSI entities. 3.4 Bridging and Virtualization Storage virtualization is a concept that abstracts storage resources in such a way that, storage entities are provided as pool of logical entities. Usually the virtualization process is transparent to the storage users (i.e. Hosts). Virtualization normally affects the SCSI entities represented to SCSI Initiators. However, the SCSI MIB enables the representation of SCSI entities and their respective status, including error and performance-monitoring statistics. It should be possible to perform a limited number of configuration modification and diagnostic actions. The SCSI entities embodied in the bridging and virtualization devices can be represented by the SCSI MIB. However, Bridging and Virtualization devices configuration is beyond the above-described scope and therefore should be provided through other MIBs. 3.5 SCSI Command MIB The management of SCSI commands is beyond the scope of this MIB. Future SCSI Command MIB can link to this MIB, through the use of OIDs or INDEX values of appropriate tables. 4. Structure of the MIB This MIB contains fourteen conformance groups: 4.1 The SCSI Device Group The scsiDeviceGroup group contains the objects general to each SCSI instance: instance, device and port objects. It contains also the objects referring to the transport(s) used by those SCSI instances. This group is mandatory for all SCSI managed system. Hallak-Stamler et al. Expires March 2003 [Page 10] SCSI MIB September 2003 4.2 The Initiator Group The scsiInitiatorGroup contains all the managed information related to a local initiator device and port. In addition, it contains the managed objects referring to the monitored attached targets. Any managed system acting, as an initiator or target/initiator port must support this group. 4.3 The Target Group The scsiTargetGroup contains all the managed objects related to a local target device, a local target port, monitored attached initiator ports, logical units and logical unit identifiers. Managed systems acting, as a target or target/initiator device and port must support this group. 4.4 The Discovery Group The scsiDiscoveryGroup group is a collection of managed objects referring to remote target devices, remote target ports, remote logical units and remote logical unit identifiers discovered by or configured to a managed system acting as an initiator device. Managed systems acting as an initiator device and port and supporting remote target devices or ports configuration or discovery should implement this group. 4.5 The LUN Map Group The scsiLunMapGroup group is a collection of managed objects allowing mapping between target devices, logical units and logical unit numbers in one side to remote authorized initiator devices or ports in another side. Managed systems supporting this mapping should implement the scsiLunMapGroup. 4.6 The Target Statistic Group The scsiTargetStatsGroup group is a collection of managed objects representing various statistics referring to a target device or port. Managed systems acting as a target device and port supporting statistics should implement this group. 4.7 The Target High Speed Statistic Group The scsiTargetHSStatsGroup group is a collection of managed objects representing various statistics referring to a target device or port. It provides support for systems, which can quickly generate countable information because they run at high speed. Hallak-Stamler et al. Expires March 2003 [Page 11] SCSI MIB September 2003 Managed systems acting, as a target device and port and running at high speed supporting should implement this group. 4.8 The LUN Map Statistics Group The scsiLunMapStatsGroup group is a collection of managed objects representing various statistics referring to remote authorized initiator devices or ports. Managed systems acting as a target device and port and able to gather statistics on remote initiator devices or ports should implement this group. 4.9 The LUN Map Statistics High Speed Group The scsiLunMapHSStatsGroup group is a collection of managed objects representing various statistics referring to remote authorized initiator devices or ports. It provides support for systems, which can quickly generate countable information because they run at high speed. Managed systems acting as a target device and port and able to gather statistics on remote initiator devices or ports and running at high speed should implement this group. 4.10 The Initiator Statistic Group The scsiInitiatorStatsGroup group is a collection of managed objects representing various statistics referring to a initiator device or port. Managed systems acting as a initiator device and port supporting statistics should implement this group. 4.11 The Initiator High Speed Statistic Group The scsiInitiatorHSStatsGroup group is a collection of managed objects representing various statistics referring to an initiator device or port. It provides support for systems, which can quickly generate countable information because they run at high speed. Managed systems acting as an initiator device and port and running at high speed supporting should implement this group. 4.12 The Discovery Statistics Group The scsiDiscoveryStatsGroup group is a collection of managed objects representing various statistics referring to remote discovered or configured target devices or ports. Hallak-Stamler et al. Expires March 2003 [Page 12] SCSI MIB September 2003 Managed systems acting as an initiator device and port and able to gather statistics on remote target devices or ports should implement this group. 4.13 The Discovery Statistics High Speed Group The scsiDiscoveryHSStatsGroup group is a collection of managed objects representing various statistics referring to remote discovered or configured target devices or ports. It provides support for systems, which can quickly generate countable information because they run at high speed. Managed systems acting as an initiator device and port and able to gather statistics on remote target devices or ports and running at high speed should implement this group. 4.14 The Device Statistics Group The scsiDeviceStatGroup group is a collection of managed objects representing various statistics referring to a SCSI device. Managed systems able to gather device statistics should implement this group. 5. Relationships in this MIB This chapter outlines the functionality and the dependency between the SNMP tables providing the required management functionality for SCSI initiator and target devices. For specific usage of these tables, the reader should refer to the description of the tables and their respective table entries and attributes. Following is a list of required SCSI initiator related features, and the respective tables facilitating this functionality: - List all the SCSI initiator ports, which should be managed through this MIB. The table scsiIntrPortTable maintains all the SCSI initiator ports for the SCSI initiator devices in the MIB. - Provide a list of all SCSI target ports or SCSI target devices to which a SCSI initiator port can attach. This should prevent a SCSI initiator device or port from attaching to SCSI target devices that should be either invisible or inaccessible to it. The entries in this list can be either created manually or by automatic discovery mechanisms (e.g. SLP, iSNS). The ScsiDscTgtTable provides this information. The entries in this table point to SCSI initiator port, and indicate that the SCSI initiator port can only attach to SCSI target ports or SCSI target devices provided in the respective entries of the ScsiDscTgtTable. Hallak-Stamler et al. Expires March 2003 [Page 13] SCSI MIB September 2003 - The information, for the aforementioned SCSI target ports or SCSI target devices, about the LUs and their respective LUN Ids should be provided. The scsiDscLunTable and scsiDscLunIdTable maintain this information. - The scsiAttTgtPortTable provides the information information about the target ports each SCSI initiator port is currently communicating with. This table should be dynamically updated to reflect those connections. Following is a list of required SCSI target related features, and the respective tables facilitating this functionality: - List all the SCSI target ports, which should be managed through this MIB. The table scsiTgtPortTable maintains all the SCSI target ports for the SCSI target devices in the MIB. -Provide a list of valid SCSI initiator ports or SCSI initiator devices authorized to attach to a SCSI target port. This list should feature the concept of "access lists", which are common in IP routers and switches. The ScsiAuthorizedIntr table provides this information. - It should be possible to specify the list of LUNs exposed to each SCSI initiator port or device, when it attached to the SCSI target. SCSI target devices must provide a default list of LUNs. This list of LUNs can be either a unique list for each SCSI initiator device, or be the default list. For each entry in the ScsiAuthorizedIntr table a pointer, named scsiAuthIntrLunMapIndex, indexing the ScsiLunMapTable facilitates this feature. - Provide means to monitor all the SCSI initiator ports currently attached to this SCSI target port. The scsiAttIntrPortTable provides this information. This table should be dynamically updated to reflect those connections. 6. Relationship to Other MIBs 6.1 Host Resource MIB The SCSI MIB extends objects defined in the host resource MIB to SCSI specific entities but does not contain information on software modules such as device drivers. If MIB objects are required for installed packages of SCSI software, then the hrSWInstalledGroup of Hallak-Stamler et al. Expires March 2003 [Page 14] SCSI MIB September 2003 the host resource MIB (RFC 2790 [RFC2790]) are the standard MIB objects to use. 6.2 iSCSI MIB The SCSI MIB defines managed objects for SCSI protocol layer. The SCSI layer can run on the top of several transport layers; iSCSI is one of them. The iSCSI MIB [IDISCSIMIB09] is the MIB portion defining the managed objects for the transport called iSCSI. In the same way, a fibre channel or parallel SCSI MIB would define managed objects for a transport called respectively fibre channel or parallel SCSI. The relationship between the SCSI MIB and any valid transport MIB is determined via the SCSI port managed table that has an object pointing to the corresponding row, if any, of the relevant table in a transport MIB. 7. Miscellaneous Details 7.1 Names and Identifiers The names and the identifiers of the SCSI devices, ports and logical units depend on the underlying transport protocols; their format and length vary accordingly. Please refer to [SAM-2] in order to get more details. 7.2 Logical Unit Number The logical unit number is a 64-bit integer. This type does not exist in SMI and therefore, this MIB contains a textual convention defining LUN as an OCTET STRING. 7.3 State of logical units The state of a logical unit determines whether the data is protected or not. It is often referred as protected entity. Protected entities are entities that are able to tolerate one or more entity failing without any loss of data or loss of data availability. For more information on the logical unit states see the SCSI Controller Commands-2 (SCC-2) standard (NCITS.318-1998). 7.4 Notifications Separate SNMP notifications may be enabled/disabled to notify of a change in any of the SCSI device status variables. A notification will be generated theoretically for each occurrence (see restriction below) of the abnormal status (e.g., if the SCSI device's current Hallak-Stamler et al. Expires March 2003 [Page 15] SCSI MIB September 2003 status is abnormal and another logical unit changes its status to from available another notification will occur). To avoid sending an excessive number of notifications due to multiple errors counted, an SNMP agent implementing the SCSI MIB should not send more than three SCSI notifications in any 10-second period. The 3-in-10 rule was chosen because one notification every three seconds was deemed often enough, but if and when two or three different notifications happen at the same time, it would not be desirable to suppress them. Three notifications in ten seconds is a happy medium, where a short burst of notifications is allowed, without inundating the network and/or destination host with a large number of notifications. 7.5 SCSI Domains SAM-2 specifies that devices belong to a domain. However, it is not usually possible to determine this from within a system, so domains are not represented within this MIB. 7.6 Counters: 32 bits and 64 bits Some counters, in (newer) high-performance systems, can increase at a fast enough rate such that their representation as Counter32's, can cause them to "wrap" in less than an hour. The SMIv2 provides Counter64 as the syntax for such counters. However, (older) SNMPv1 implementations cannot support Counter64's. Thus, this MIB defines such counters as both Counter32's and Counter64's. The counters in this MIB which count data, are defined in terms of megabytes (i.e., as the number of megabytes of data), such that Counter64's are not required. However, the counters in this MIB, which count commands, when in use at 10GBit/second with 512 read/write operations, could wrap within an hour. Therefore, each of these counters will be defined as both a Counter32 and a Counter64, with the latter being conditionally mandatory, depending on the system speed. 7.7 Local versus Remote Entities This MIB qualifies often SCSI entities as local or remote. The local entities are the ones for which the agent is reporting. The remote entities are the ones, which the local entities are in communication with via the SCSI protocol. 8.

In particular, the contributions of Sajay Selvaraj (HCL Technologies), George Penokie (IBM) and Roger Cummings (Veritas Software) were critical to the formulation of this specification. 11. Object Population Example: Target and Initiator on a pSCSI bus This section provides a sample set of values for a parallel SCSI scenario in which a SCSI MIB can be implemented. The example shown below is not a normative part of this draft and makes some assumptions about the underlying implementation, which are not based on actual implementations. The respective sections describe the sequence of object instantiations and attempts to explain non-typical values for attributes that are unique to the scenario. Note: While populating the objects, the population of statistics is not considered. This scenario deals with a SCSI target and initiator attached to a parallel SCSI bus. We assume an HBA as the initiator and a disk as target. We assume that the target has one logical unit, addressed by logical unit number set to 0 (LUN0), which is the default LUN. Parallel SCSI only has port identifiers, no port names. The transport pointer for parallel SCSI is set to 0 since, there is no reference transport (SPI) MIB protocol. Once the SCSI system is initialized, SNMP agent should be able to view the values of variables populated in the ScsiDevice, ScsiInitiatorDevice, ScsiTargetDevice, ScsiPort, ScsiTargetPort, ScsiInitiatorPort, ScsiLogicalUnit, ScsiLUIdentifier objects. The ScsiTgtAuthorizedIntr population depends on the transport and the implementation. As this example scenario is parallel scsi, we deal with the ports. Hence the ScsiPortIndexOrZero is the index of the target port and ScsiTgtAuthIntrDevOrPort is "port". Same is the case with the variables in ScsiIntrAuthorizedTgt also. 11.1 scsiInstance Table: Attribute Value Hallak-Stamler et al.

Security Considerations There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure Hallak-Stamler et al. Expires March 2003 [Page 75] SCSI MIB September 2003 environment without proper protection can have a negative effect on network operations. These are: * scsiIntrDevTgtAccessMode: this object can be manipulated to allow immediate access by local initiators to discovered targets without waiting for administrator approval, where such approval might not be forthcoming. * scsiDscTgtTable: the objects in this table can be manipulated to remove administrator-specified controls on access by local initiators to discovered targets. * scsiAuthorizedIntrTable: the objects in this table can be manipulated to remove administrator-specified controls on access by remote initiators to local targets. * scsiLunMapTable: the objects in this table can be manipulated to provide access by a remote initiator to logical units which an administrator has configured as not accessible to said initiator. In each of the above cases, the objects in the tables can also be manipulated to cause a Denial-of-Service attack, by preventing administrator-authorized access. Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability: * scsiTgtDevTable contains information on target devices and * scsiLuTable contains information on logical units. These information may need to be kept private in sensitive environments. SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to Hallak-Stamler et al. Expires March 2003 [Page 76] SCSI MIB September 2003 the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them. 15.
