static (iSCSI initiator configuration and iSLB initiator configuration) Chapter 21 S Commands Send documentation comments to [email protected] static (iSCSI initiator configuration and iSLB initiator configuration) To assign persistent WWNs to an iSCSI initiator or iSLB initiator, use the static command in iSCSI initiator configuration submode or iSLB initiator configuration submode. To disable this feature, use the no form of the command. static {nwwn | pwwn} {wwn-id | system-assign} no static {nwwn | pwwn} {wwn-id | system-assign} Syntax Description nwwn pwwn wwn-id system-assign Configures the initiator node WWN hex value. Configures the peer WWN for special frames. Specifies the pWWN or nWWN ID. Generates the pWWN or nWWN value automatically. Defaults None. Command Modes iSCSI initiator configuration submode. iSLB initiator configuration submode. Command History Release 1.3(2) 3.0(1) Modification This command was introduced. Added iSLB initiator configuration submode. Usage Guidelines We recommend using the system-assign option. If you manually assign a WWN, you must ensure its uniqueness. You should not use any previously-assigned WWN. If you use system-assign option to configure WWNs for an iSLB initiator, when the configuration is saved to an ASCII file, the system-assigned WWNs are also saved. If you subsequently perform a write erase, you must manually delete the WWN configuration from the ASCII file. Failing to do so can cause duplicate WWN assignments if the ASCII configuration file is reapplied on the switch. Examples The following example uses the switch WWN pool to allocate the nWWN for this iSCSI initiator and to keep it persistent. switch# config terminal Enter configuration commands, one per line. End with CNTL/Z. switch(config)# iscsi initiator name iqn.1987-02.com.cisco.initiator switch(config-iscsi-init)# static nWWN system-assign 21-62 Cisco MDS 9000 Family Command Reference OL-16217-01, Cisco MDS SAN-OS Release 3.x
