    3. (Optional) You can add and edit user-defined names for WWNs.
    4. You can select a reference WWN to add the new WWN into host groups to which the reference WWN belongs.
      Note: If reference WWN is specified, Apply changes to attached volumes must also be verified.
    5. Unselect the Apply changes to attached volumes check box if you do not want to make the following changes:
      • If a WWN has been updated, all host groups with the old WWN are updated with the new one. All zones created in Ops Center Administrator have the old WWN removed and new address populated.
      • If a WWN is deleted, it will be removed from any host group that has it. If the host group is left with no WWNs, the entire host group is deleted. All zones created in Ops Center Administrator have the deleted WWN removed.
      • If you add a reference WWN, host groups are edited. If you do not add a reference WWN, no host groups are edited. You can use Ops Center Administrator to add paths using the new LUN.

      • If an iSCSI initiator name has been updated, all iSCSI targets with the old iSCSI name are updated with the new one.
      • If an iSCSI initiator name is deleted, it will be removed from any iSCSI target that has it. If the iSCSI target is left with no iSCSI initiator names, the entire iSCSI target is deleted.
      • If an iSCSI initiator name is added, no iSCSI targets are edited. You can use Ops Center Administrator to add paths using the new LUN.
      • If a CHAP user information changes, Ops Center Administrator will update the information on the storage system.
