Deleting all capacity saving-enabled DP-VOLs in a pool

When a deduplication system data volume is assigned to a pool, use this workflow to delete all of the capacity saving-enabled DP-VOLs in the pool. If the pool does not have a deduplication system data volume, you must use the delete DP-VOL procedure.

This operation formats DP-VOLs. Its execution time is increased by one minute per total capacity 40TB of all DP-VOLs whose Deduplication Data status is Enabled.

Execution time = 5 [min.] + ceil(Total capacity [TB] รท 40 [TB])

For example, when the total capacity is 100 TB, the execution time is calculated as follows:

5 + ceil(100/40) = 5 + ceil(2.5) = 8[min.]
  1. Block all of the following volumes that are allocated to the target pool using the Block LDEVs window.
    • All of the DP-VOLs whose Deduplication Data status is Enabled.
    • The deduplication system data volume for the pool.
  2. Format the (blocked) deduplication system data volume using the Format LDEVs window. Make sure to specify only the single deduplication system data volume for the target pool.
  3. Format all of the (blocked) DP-VOLs whose Deduplication Data status is Enabled in the pool using the Format LDEVs window.
    NoteThe formatting operations for DP-VOLs whose Deduplication Data status is Enabled might take a lot of time.
  4. Delete all of the (formatted) DP-VOLs whose Deduplication Data status is Enabled in the pool.

    You cannot delete a deduplication system data volume (DSD volume). The deduplication system data volume for a pool is deleted automatically when you disable the Capacity Saving setting for the pool or delete the pool.
