Description: Manages iSCSI (SCSI over TCP) implementations, providing configuration, fault, and statistics for iSCSI targets, initiators, sessions, and connections.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring ISCSI-MIB with a free 30-day trial of IPNetwork Monitor.

What Is ISCSI-MIB?

This is the IETF standard MIB for managing iSCSI (SCSI over TCP/IP) implementations, covering iSCSI targets, initiators, sessions, and connections. It exposes instance-level attributes such as protocol version support, vendor identification, and counts of configured portals/nodes/sessions, alongside notification and conformance groups. It is used to monitor the software/service status of the iSCSI stack, particularly session-failure counts, which reveal connectivity or storage-access problems between initiators and targets. As an IETF MIB it is a standards-based module with no vendor dependency, often deployed alongside standard TCP and interface MIBs. It is deployed on storage servers, SANs, and hosts using iSCSI for block storage access over IP networks. Engineers implementing or auditing this functionality typically reference the ISCSI-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in ISCSI-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

vendor-neutral, standards-based IETF MIB, not tied to a specific manufacturer
iSCSI targets, initiators, and storage servers/SANs

Monitoring Examples

iscsiInstanceAttributesTable/iscsiInstanceAttributesEntry, indexed by iscsiInstIndex, exposes iscsiInstDescr, iscsiInstVendorID, and iscsiInstVendorVersion for identifying the iSCSI implementation, while iscsiInstPortalNumber, iscsiInstNodeNumber, and iscsiInstSessionNumber track how many portals/nodes/sessions are active. An admin polling iscsiInstSsnFailures would detect a rising count indicating iSCSI sessions are repeatedly failing to establish, pointing to a network or target-side storage problem.

What Can Be Monitored

iSCSI instance version/vendor info
portal/node/session counts
session failure count

How to Use in IPNetwork Monitor

Example using iscsiInstSsnFailures OID:

Select a device implementing ISCSI-MIB as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type iscsiInstSsnFailures into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This object counts the number of times a session belonging to this instance has failed. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

When adding a row to this table, all non-Index/RowStatus objects must be set. When the value of this object is 'active', the values of the other objects in this table cannot be changed. Rows may be discarded using RowStatus. Note that creating a row in this table will typically cause the agent to create one or more rows in the iscsiTgtPortalAttributesTable and/or the iscsiIntrPortalAttributesTable.
BIT iscsiPortalRoles	1.3.6.1.2.1.142.1.2.1.1.3	Bits	read-create	A portal can operate in one or both of two roles: as a target portal and/or an initiator portal. If the portal will operate in both roles, both bits must be set. This object will define a corresponding row that will exist or must be created in the iscsiTgtPortalAttributesTable, the iscsiIntrPortalAttributesTable, or both. If the targetTypePortal bit is set, one or more corresponding iscsiTgtPortalAttributesEntry rows will be found or created. If the initiatorTypePortal bit is set, one or more corresponding iscsiIntrPortalAttributesEntry rows will be found or created. If both bits are set, one or more corresponding rows will be found or created in one of the above tables.

This object is designed to accommodate future error-recovery levels. Higher error-recovery levels imply support in addition to support for the lower error level functions. In other words, error level 2 implies support for levels 0-1, since those functions are subsets of error level 2.
TIM iscsiNodeDiscontinuityTime	1.3.6.1.2.1.142.1.5.1.1.17	TimeStamp	read-only	The value of SysUpTime on the most recent occasion at which any one or more of this node's counters suffered a discontinuity. If no such discontinuities have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value.
STO iscsiNodeStorageType	1.3.6.1.2.1.142.1.5.1.1.18	StorageType	read-write	The storage type for all read-write objects within this row. Rows in this table are always created via an external process (e.g., not created via this MIB module). Conceptual rows having the value 'permanent' need not allow Write access to any columnar objects in the row. If this object has the value 'volatile', modifications to read-write objects in this row are not persistent across reboots. If this object has the value 'nonVolatile', modifications to objects in this row are persistent. An implementation may choose to allow this object to be set to either 'nonVolatile' or 'volatile', allowing the management application to choose this behavior.

TIM iscsiTgtLastFailureTime	1.3.6.1.2.1.142.1.6.1.1.2	TimeStamp	read-only	The timestamp of the most recent failure of a login attempt to this target. A value of zero indicates that no such failures have occurred since the last system boot.
OID iscsiTgtLastFailureType	1.3.6.1.2.1.142.1.6.1.1.3	AutonomousType	read-only	The type of the most recent failure of a login attempt to this target, represented as the OID of the counter object in iscsiTargetLoginStatsTable for which the relevant instance was incremented. If no such failures have occurred since the last system boot, this attribute will have the value 0.0. A value of 0.0 may also be used to indicate a type that is not represented by any of the counters in iscsiTargetLoginStatsTable.
