If you no longer want to access data in an external volume, you can delete the mapping. When you do, the data in the external volume is not deleted.

  • You must have the Storage Administrator (Provisioning) role.
  • If you disconnect the external volume or volumes, before you delete them, all the data in the cache memory is written to the external volume.

    However, you can delete a volume without disconnecting, meaning that data in cache memory is not destaged to the external volume.

  • You cannot delete a mapping while the external volume is used in the following:
    • TrueCopy, Universal Replicator, ShadowImage, Thin Image, or global-active device.
    • A reserved volume for ShadowImage or Volume Migration.
    • A pool-VOL
    • A Quorum Disk
  • For command devices, stop the application using the external volume as a command device.
