initiator# iscsiadm list target Target: iqn.2001-05.com.abcstorage:6-8a0900-37ad70401-bcfff02df8a421df-zzr1200-01 TPGT: default ISID: 4000002a0000 Connections: 0
You can also verify whether the connection is accessible by using the ping command or by connecting to the storage device's iSCSI port by using the telnet command to ensure that the iSCSI service is available. The default port is 3260.
In addition, check the storage device's log file for errors.
If you are using SendTargets as the discovery method, try listing the discovery-address by using the –v option to ensure that the expected targets are visible to the host. For example:
initiator# iscsiadm list discovery-address -v 10.0.0.1 Discovery Address: 10.0.0.1:3260 Target name: eui.210000203787dfc0 Target address: 10.0.0.1:11824 Target name: eui.210000203787e07b Target address: 10.0.0.1:11824
If you are using iSNS as the discovery method, try enabling the iSNS discovery method and listing the isns-server using the –v option to ensure that the expected targets are visible to the host. For example:
initiator# iscsiadm list isns-server -v iSNS Server IP Address: 10.20.56.56:3205 Target name: iqn.1992-08.com.xyz:sn.1234566 Target address: 10.20.57.161:3260, 1 Target name: iqn.2003-10.com.abc:group-0:154:abc-65-01 Target address: 10.20.56.206:3260, 1 Target name: iqn.2003-10.com.abc:group-0:154:abc-65-02 Target address: 10.20.56.206:3260, 1 . . .
