You can delete pools that have a 0% usage rate and that are not assigned for DP-VOLs.

Deleting a pool blocks its pool-VOLs (LDEVs). To use blocked pool-VOLs, format the volumes.

Note: If the blocked pool-VOL is an external volume, select Normal Format when formatting the volume.

When you specify an LDEV belonging to an accelerated compression-enabled parity group by using HDvM - SN or CCI to shrink a pool that contains the LDEV, for VSP E series, the pool auto-expansion function of the parity group to which the LDEV specified for shrinking the pool belongs is disabled. After the pool is shrunk, if you enable the automatically adding pool volumes function in the parity group where the LDEV specified when shrinking the pool belongs, disable accelerated compression of the pool first, and then enable it again. If the SIM code is 602xxx (where xxx is a pool number) , enable accelerated compression without performing the countermeasure for the SIM.

For more information about DP-VOL requirements, see the Provisioning Guide for your storage system.

  • You must have the Storage Administrator (Provisioning) role.
  • In CCI, use the raidcom delete pool command.
  1. In the Explorer pane, click Storage Systems, expand the storage system tree, and then click Pools.
