Monitoring Your iSCSI Configuration

You can display information about the iSCSI initiator and target devices by using the iscsiadm list command.

Display information about the iSCSI initiator.

For example:

# iscsiadm list initiator-node
Initiator node name: iqn.1986-03.com.sun:01:0003ba4d233b.425c293c
Initiator node alias: zzr1200
        Login Parameters (Default/Configured):
                Header Digest: NONE/-
                Data Digest: NONE/-
        Authentication Type: NONE
        RADIUS Server: NONE
        RADIUS access: unknown
        Configured Sessions: 1

Display information about which discovery methods are in use.

For example:

# iscsiadm list discovery
Discovery:
    Static: enabled
    Send Targets: enabled
    iSNS: enabled

Example 12-1 Displaying iSCSI Target Information

The following example shows how to display the parameter settings for a specific iSCSI target.

# iscsiadm list target-param iqn.1992-08.com.abcstorage:sn.33592219
        Target: iqn.1992-08.com.abcstorage:sn.33592219

The iscsiadm list target-param -v command displays the following information:

The authentication settings for the target
The default settings for the target login parameters
The configured value for each login parameter

The iscsiadm list target-param -v command displays the default parameter value before the / designator and the configured parameter value after the / designator. If you have not configured any parameters, the configured parameter value displays as a hyphen (-). For more information, see the following examples.

# iscsiadm list target-param -v eui.50060e8004275511 Target: eui.50060e8004275511
        Alias: -
        Bi-directional Authentication: disabled
        Authentication Type: NONE
        Login Parameters (Default/Configured):
                Data Sequence In Order: yes/-
                Data PDU In Order: yes/-
                Default Time To Retain: 20/-
                Default Time To Wait: 2/-
                Error Recovery Level: 0/-
                First Burst Length: 65536/-
                Immediate Data: yes/-
                Initial Ready To Transfer (R2T): yes/-
                Max Burst Length: 262144/-
                Max Outstanding R2T: 1/-
                Max Receive Data Segment Length: 65536/-
                Max Connections: 1/-
                Header Digest: NONE/-
                Data Digest: NONE/-
        Configured Sessions: 1

The following example output displays the parameters that were negotiated between the target and the initiator.

# iscsiadm list target -v eui.50060e8004275511
