Deleting an external volume mapping

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.

Before you begin

  • 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.
  • Storage Administrator (Provisioning) role
