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

RAID Manager to shrink a pool that contains the LDEV,
Automatically manage compressed space of
FMD parity group is set to Disable. 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,

countermeasure for the SIM.
