Deleting pools

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.

NoteIf 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, Automatically manage compressed space of FMD parity group is set to Disable for VSP F1500, VSP G1x00. For VSP G/F350, G/F370, G/F700, G/F900, the automatically adding pool volumes 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 604xxx or 605xxx is reported (for VSP F1500, VSP G1x00, where xxx is a pool number), 601xxx or 602xxx (for VSP Fx00 models, VSP Gx00 models) , 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.
