1. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
Hallak-Stamler et al. Expires August 2002 [Page 2]
SCSI MIB January 2002
o An overall architecture, described in RFC 2571 [1].
o Mechanisms for describing and naming objects and events for
the purpose of management. The first version of this
Structure of Management Information (SMI) is called SMIv1 and
described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and
RFC 1215 [4]. The second version, called SMIv2, is described
in STD 58, RFC 2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC
2580 [7].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1
and described in STD 15, RFC 1157 [8]. A second version of
the SNMP message protocol, which is not an Internet standards
track protocol, is called SNMPv2c and described in RFC 1901
[9] and RFC 1906 [10]. The third version of the message
protocol is called SNMPv3 and described in RFC 1906 [10], RFC
2572 [11] and RFC2574[12].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[13].
o A set of fundamental applications described in RFC 2573 [14]
and the view-based access control mechanism described in RFC
2575[15].
A more detailed introduction to the current SNMP Management
Framework can be found in RFC 2570 [16].
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.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine-readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of
machine-readable information is not considered to change the
semantics of the MIB.
2. Conventions

they appear in this document, are to be interpreted as described in
RFC 2119 [23].
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. The MIB is based on documents issued by the T-10 Technical
Committee and specially on SAM-2 (SCSI Architecture Model - 2)
document [17].
The SCSI protocol is a client-server protocol allowing an
application layer client to transmit commands to a device server and
to a task manager using an interconnect subsystem.
The client side is referred as the initiator side and the server
side is referred as the target side.
A target includes a collection of logical units; each logical unit
has a task manager allowing an initiator to execute commands.
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 defined an 8 bit wide multi-drop ææbusÆÆ structure which could
interconnect a total of eight peripherals and computer systems.
ItÆs important to realize that all SCSI initially standardized was
the ææphysical connectionÆÆ 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.
Hallak-Stamler et al. Expires August 2002 [Page 4]
SCSI MIB January 2002
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 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 know as iSCSI, and an iSCSI
MIB is already under development.

3.2 SCSI Terminology
The definitions below are part of T.10 Proposal for SAM-2 [17]. They
are copied from [17].
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 device-resident object that connects the application client,
device server or task manager to the service delivery subsystem
through which requests and responses are routed. SCSI port is
synonymous with port and either a SCSI initiator port or a SCSI
target port.
3.2.4 SCSI Initiator Device
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 device object 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 device containing logical units and SCSI target ports that
receives device service and task management requests for processing.
When used this term refers to SCSI target devices or SCSI
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 device object 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.
Hallak-Stamler et al. Expires August 2002 [Page 7]
SCSI MIB January 2002
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 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
Logical Unit Number or LUN is a 64-bit identifier for a logical
unit.
3.2.10 Nexus
A nexus is a relationship between two SCSI devices and the initiator
and target objects within those SCSI devices.
I_T Nexus: A nexus between an initiator and a target
I_T_L Nexus: A nexus between an initiator, a target and a
logical unit.
I_T_L_Q Nexus: A nexus between an initiator, a target, a
logical unit and a tagged task.
I_T_L_x Nexus: Either am I_T_L nexus or an I_T_L_Q nexus.
3.2.11 Interconnect subsystem
One or more physical interconnects that appear as a single path for
the transfer of information between SCSI devices.
3.2.12 Device Server
A device server is an object within the logical unit that processes
SCSI tasks according to the rules for task management.
3.2.13 Task Manager
A task manager is a server within the target that processes task
management functions.
3.3 SCSI MIB implementations
The SCSI MIB is a basic building block to use in the various SCSI
management scenarios.
The SCSI MIB will be implemented in every SCSI entity in the system.
A SCSI entity can be a SCSI Initiator device, SCSI Target device or
SCSI Initiator and Target device. As SCSI devices may contain more
than one SCSI entity, it is possible that more than one SCSI MIB
instance, and its respective agent, will reside in a single device.
Along this chapter figures have been provided to describe the
location of the SCSI MIB implementation in the various SCSI
management scenarios.
The location of the SCSI SNMP agent implementing the SCSI MIB are
denoted with '*'.

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.
'TBD AttachedObjects description'
In addition to the SCSI transport (e.g. parallel SCSI, FCP, iSCSI),
a management interface and transport (e.g. UDP),is provided in both
the Target and the Initiator.

Figure 2: Multiple Hosts and a Single Target device
Figure 2 adds another SCSI Initiator device, to the SCSI network,
which connects to the same SCSI target device.
The Initiator also implements a SNMP SCSI agent. In this case the

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
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 might implement
additional proprietary MIBs, as the SCSI MIB does not provide this
kind of functionality.
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 the storage users
(i.e. Hosts). Virtualization normally affects the SCSI entities
represented to SCSI Initiators. However, the SCSI MIB should enable
Hallak-Stamler et al. Expires August 2002 [Page 10]
SCSI MIB January 2002
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 should be represented by the SCSI MIB. However, Bridging and
Virtualization devices configuration is beyond the above-described
scope and therefore should be provided through enterprise MIBs.
4.Structure of the MIB
This MIB is composed as traditionally with three main groups:
. scsiObjects
. scsiNotifications
. scsiConformance
The scsiObjects group is composed itself of four groups:
4.1 General Group
The scsiGeneral group contains the parameters general to the
managed scsi entity. It contains also the generic device and port
tables.
Note that a SCSI entity may contain more than one SCSI device and
more than one SCSI port.
4.2 Initiator Group
The scsiInitiator group contains all the managed information
related to an initiator device and port. In addition, it contains
the scsiIntrDiscoveredTarget group that will allow a manager to
check the targets and LUNs devices discovered by an initiator device
or port.
4.3 Target Group
The scsiTarget group contains all the managed information related
to a target device and port. In addition, it contains the
scsiLogicalUnit group that summarizes all the managed information
concerning logical units, LUN hierarchy and logical unit
identifiers.
4.4 The Transport Group
This group is a collection of transports that can be used by SCSI.
The transport fixes the format of SCSI Names and Identifiers.
5.Relationship to Other MIBs
5.1 Host Resource MIB
This portion of MIB extends those managed objects to SCSI specific
entities but doesn't contain reference to software like device
driver. If MIB objects are required for installed packages of SCSI
software, then the hrSWInstalledGroup of the host resource MIB (RFC
2790 [22]) are the standard MIB objects to use.
Hallak-Stamler et al. Expires August 2002 [Page 11]
SCSI MIB January 2002
5.2 iSCSI MIB
To be supplied.
6. MIBS Specific Issues
6.1 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 [20] in order
to get more details.
6.2 Logical Unit Number
The logical unit number is a 64-bit integer. This type does not
exist in SMI and therefore, we need to define it as a textual
convention for this MIB.
6.3 State and status
Definitions:
- Protected: Protected objects are objects that are able to
tolerate one or more objects failing without any loss of data or
loss of data availability.
Reference:
For more information on the logical unit states see the SCSI
Controller Commands-2 (SCC-2) standard (NCITS.318-1998)
Notification:
Separate SNMP traps may be enabled/disabled to notify of a change in
any of the SCSI device status variables. A notification will be
generated for each occurrence of the abnormal status (e.g., if the
SCSI deviceÆs current status is abnormal and another logical unit
changes its status to from available another notification will
occur). Other restrictions as to the frequency of the notifications
are TBD.
6.4 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.Objects Population Examples
Directly Attached SCSI Disk:
----------------------------
Hallak-Stamler et al. Expires August 2002 [Page 12]
SCSI MIB January 2002
In this case, the HBA will act as the scsi initiator and a scsi disk
attached to the bus acts as the scsi target. Here we consider a
simple case of a single logical unit with a single LUN.
Considerations for including this topology:
-----------------------------------------
This is a simple case, which can be used to validate the basic
soundness of the model from a parallel SCSI point of view.
Population of the objects:
--------------------------
ScsiDevice:
-----------
For each device in the scsi bus, there is a corresponding row in the
table.
In this scenario we have two scsi devices hence we will have two
rows created.
scsiInstanceIndex ->0001
scsiDeviceIndex ->An arbitrary index for the each device to be
uniquely identified
scsiDeviceType --> Initiator/Target/Initiator-Target
scsiDeviceName -->A name assigned to each scsi device in the
given scsi instance (by administrator?)
The populated ScsiDevice table for this scenario:
--------------------------------------------------
scsiInstIndex 0001 0001
scsiDeviceIndex 0001 0002
SerialNumber 0001 0002
scsiDeviceType I T
scsiDeviceName Initiator-xxx Target-yyy
ScsiTargetDevice:
-----------------
scsiInstanceIndex -> 0001
scsiDeviceIndex -> An arbitrary index to uniquely identify
each device.
Hallak-Stamler et al. Expires August 2002 [Page 13]
SCSI MIB January 2002
NumberOflUs -> Number of LUs associated with this
target. In our current scenario we have only
one logical unit associated with the target
device.
scsiInstIndex 0001
scsiDeviceIndex 0002
NumberOfLUs 1
ScsiInitiatorDevice Object:
---------------------------
scsiInstanceIndex -> 0001
scsiDeviceIndex -> Arbitrary index to uniquely identify each device.
scsiInstIndex 0001
scsiDeviceIndex 0002
ScsiPort Object:
----------------
This object will give a list of active SCSI Ports for each SCSI
device in the instance. Hence the table will get populated with
number of rows equivalent to the total number of active ports of all
the scsi devices in the scsi instance. Here, we have two active
ports one is an initiator port and one is a target port.
scsiInstanceIndex ->0001
scsiDeviceIndex ->An arbitrary index for the each device to get
uniquely identified
scsiPortIndex ->An arbitrary index for each port to get uniquely
identified.
scsiPortType ->This attribute states the type of the scsiport
('I'->Initiator port; 'T'->Targetport;
'IT'->Initiator/Targetport)
scsiInstIndex 0001 0001
scsiDeviceIndex 0001 0002
scsiPortIndex 0001 0002
scsiPortType I T
scsiInitiatorPort object:
-------------------------
This table contains all the initiator ports of each SCSI Initiator
or Target/Initiator device. In our scenario we have one initiator
Hallak-Stamler et al. Expires August 2002 [Page 14]
SCSI MIB January 2002
device with one initiator port. So this table is populated with only
one row.
scsiInstanceIndex -> 0001
scsiDeviceIndex -> An arbitrary index to uniquely
identify each device.
scsiPortIndex -> An arbitrary index to uniquely
identify each port.
InitiatorPortName -> Name of the port assigned by the SCSI
protocol.
InitiatorPortIdentifier ->This is an identifier assigned to the
port by SCSI.
scsiInstIndex 0001
scsiDeviceIndex 0001
scsiPortIndex 0001
InitiatorPortName I_sample_port
InitiatorPortIdentifier 1000
ScsiTargetPort object:
----------------------
This table contains all the target ports of each SCSI Target or
Target/Initiator device.
In our scenario we have only one target device with one target port.
scsiInstanceIndex -> 0001
DeviceIndex -> An arbitrary index for the each device to
get uniquely identified.
PortIndex -> An arbitrary index for each port to get
uniquely identified.
TgtPortName -> Name of the port assigned by the scsi
protocol
TgtPortIdentifier ->This is an identifier assigned to the port by
the scsi protocol
scsiInstIndex 0001
scsiDeviceIndex 0002
scsiPortIndex 0002
TargetPortName T_sample_port
TargetPortIdentifier 1001
ScsiLogicalUnit:
----------------
This table includes all the logical units exposed by a target
device. We have only one logical unit on the target device.
scsiInstanceIndex -> 0001
scsiDeviceIndex -> 0002
Hallak-Stamler et al. Expires August 2002 [Page 15]
SCSI MIB January 2002
scsiLUIndex -> Administrative index in the Logical Unit table.
scsiDefaultLun -> This attribute represents a simple case in which
one logical unit will have one LUN assigned in which
case LU_IPort_Info will not be populated.
As this is a simple case of one LU having one LU
we will have this value as 0.which is the default
LUN.
LuName -> The World-Wide Name of this LU. This name should
be unique within the scsi instance.
VendorId -> Identifier of the vendor of this logical uni
ProductId -> A string identifying the product for this LU.
RevisionId -> A string defining the product revision of this
LU.
scsiInstIndex 0001
scsiDeviceIndex 0002
scsiLUIndex 0001
scsiLUparent 0
scsiDefaultLUN 0
LUName LLL
Vendorid XYZ
productid PQR
revisonId ABC
LU_IPort_Info:
--------------
This object is populated when there is more than one LUN to a single
logical unit. Also this will have the persistent information about
an initiator on a LU a basis. In our current we have one initiator
and one target with single LUN.
As this is a simple case with one LU having one LUN, this object
will not be populated in this scenario.
ScsiTgtAttIntrPort:
---------------------
This object will be populated with the state information of
initiators currently active. So this object will have the state info
of the initiators currently attached to every target port. In our
scenario we have a target device with one target port .So this table
will populate, for each target port, all the attached initiator
ports attached dynamically.
In our scenario we will get one row populated for one initiator
device with one port.
scsiInstanceIndex ->0001
scsiDeviceIndex ->An arbitrary index for the each device to
get uniquely identified
scsiPortIndex ->An arbitrary index for each port to get
uniquely identified.

scsiAttIntrIndex ->Index of the initiator, which has attached to
this port.

been attached to this port.

ScsiAttachedTarget object:
-------------------------
This object resembles the one discussed above.
TPort_IPort_Info:
-----------------
This object will contain persistent information a target may be
keeping about Initiators. If the administrator configures certain
LUNs for certain initiators, the information is persistent. The
agent will collect this info into this object.
In our scenario we don't have concept of configured initiators hence
this table is not populated. ***********This is a doubt*********

DESCRIPTION
"This textual convention is an extension of the
ScsiIndexValue convention. The latter defines a greater than
zero value used to identify an index. This extension permits
the additional value of zero and is applicable only to
indices of SCSI port. The value zero is object-specific and
must therefore be defined as part of the description of any
object, which uses this syntax. Examples of the usage of
zero might include situations where index was unknown, or
when none or all indices need to be referenced."

13. Security Considerations
Hallak-Stamler et al. Expires August 2002 [Page 48]
SCSI MIB January 2002
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
environment without proper protection can have a negative effect on
network operations.
Some managed objects in this MIB may contain sensitive information.
SNMPv1 by itself is not a secure environment. 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.
It is recommended that the implementers consider the security features
as provided by the SNMPv3 framework. Specifically, the use of the
User-based Security Model RFC 2574 [12] and the View-based Access
Control Model RFC 2575 [15] are recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
