Deleting a DP-VOL

Use this procedure to delete a DP-VOL.

Note
  • You cannot delete a deduplication system data volume (DSD volume). The deduplication system data volume for a pool is deleted automatically in either of the following cases:
    • If you delete all DP-VOLs of which the capacity saving setting is Deduplication and Compression in a pool or delete a pool.
    • If the capacity saving setting is changed from Dedeuplication and Compression to Disable for all DP-VOLs in a pool by using the Edit LDEVs window.
  • You cannot delete a DP-VOL if the status is online.
  • If you are deleting a DP-VOL with Deduplication and Compression enabled, you must first disable Deduplication and Compression on the DP-VOL before beginning this procedure.
  • After you delete a DP-VOL for which capacity saving is enabled, if you perform other operations during or just after the DP-VOL deleting processing, those operations might fail. If this occurs, wait for a while, and then retry those operations.
  • The LDEV deleting process is suspended when the size of the used capacity or physical used capacity of a pool reaches the depletion threshold. If this occurs, you must resolve the causes of the SIM message. When enough pool capacity is ensured, the deleting process will start again.
CautionIf the SVP or a Device Manager - Storage Navigator secondary window is in Modify mode while the rehydration processing of the capacity-saving-enabled DP-VOLs is in progress, a conflict occurs and the rehydration processing does not complete (Capacity Saving Status remains Rehydrating). In this case, change the SVP or secondary window to View mode.
