You can display information about the iSCSI initiator and target devices by using the iscsiadm list command as an administrator.
The following example shows how to display information about which discovery method is used.
# iscsiadm list discovery Discovery: Static: disabled Send Targets: disabled iSNS: enabled
The following examples show how to display discovered targets.
The following example shows how to display information about an iSCSI initiator by using the iscsiadm list initiator-node command.
# 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/-

The following example shows how to display the parameter values for a specific iSCSI target.
# iscsiadm list target

# iscsiadm list target-param iqn.1986-03.com.sun:02:02380f80-ab3c-47a9-8882-d3cafc2c49ae Target: iqn.1986-03.com.sun:02:02380f80-ab3c-47a9-8882-d3cafc2c49ae Alias: -
The iscsiadm list target-param –v command displays the following information:
The authentication values for the target
The default values 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 a parameter, its value displays as a hyphen ( - ). The following example shows the parameters that were negotiated between the target and the initiator.
# iscsiadm list target-param -v
