Chapter 11 I Commands iscsi duplicate-wwn-check Send documentation comments to [email protected] iscsi duplicate-wwn-check To check the current running configuration for conflicts between iSCSI initiators' static WWN allocation and what the system thinks is available in its WWN pool, use the iscsi duplicate-wwn-check command in configuration mode. iscsi duplicate-wwn-check Syntax Description This command has no arguments or keywords. Defaults None. Command Modes Configuration mode. Command History Release 2.1(2) Modification This command was introduced. Usage Guidelines Prior to Cisco MDS SAN-OS Release 2.1(2), WWNs assigned to static iSCSI initiators by the system can be inadvertently returned to the system when an upgrade fails or the system software is manually downgraded (that is, when you manually boot up an older Cisco MDS SAN-OS release without using the install all command). In these instances, the system can later assign those WWNs to other iSCSI initiators (dynamic or static) and cause conflicts. As of Cisco MDS SAN-OS Release 2.1(2), you can use the iscsi duplicate-wwn-check command to check for and remove any configured WWNs that belong to the system. Note This command is not supported on the Cisco MDS 9124 switch, the Cisco Fabric Switch for HP c-Class BladeSystem, and the Cisco Fabric Switch for IBM BladeCenter. Examples The following example shows how to check the current running configuration for conflicts between iSCSI initiators' static WWN allocation and what the system thinks is available in its WWN pool. switch# config terminal Enter configuration command, one per line. End with CNTL/Z. switch(config)# iscsi duplicate-wwn-check List of Potential WWN Conflicts Node : iqn.test-local-nwnn:1-local-pwwn:1 nWWN : 22:03:00:0d:ec:02:cb:02 pWWN : 22:04:00:0d:ec:02:cb:02 The following example shows how to remove the conflicting nWWN and pWWN. switch(config)# iscsi initiator name iqn.test-local-nwwn:1-local-pwwn:1 switch(config-iscsi-init)# no static nWWN 22:03:00:0d:ec:02:cb:02 OL-16217-01, Cisco MDS SAN-OS Release 3.x Cisco MDS 9000 Family Command Reference 11-83
