  1. Change the WWN/iSCSI target name of the external storage.
    See the Provisioning Guide for detailed procedures. Changing the WWN/iSCSI target name blocks the external path that uses the target port with a WWN/iSCSI target name that has been changed.
  2. Add an external path between the local storage system and target port with a WWN/iSCSI target name that has been changed.
  3. Delete the external path that was blocked in step 1.

Before deleting external volume mapping, make sure that the volume has no LU paths or the volume is not assigned to a namespace on the NVM subsystem with an NVM subsystem port added for NVMe, and that the volume is not part of a copy pair. See Deleting an external volume mapping for instructions.
