Syntax

• storagepool-name: Identifies an Exascale storage pool that you want to modify.

  Use the describe chstoragepool command to view details about the storage pool attributes you can modify with chstoragepool.

• --reconfig: Reconfigures the storage pool and makes permanent any changes to the number or size of the underlying pool disks.

The time required for reconfiguration depends on the amount of data movement required to rebalance the storage pool.

• --force: Optionally forces a reconfiguration operation even if the system detects no apparent change to the underlying pool disks.
