Increasing pool capacity

Adding pool-VOLs to a pool increases, or expands, the pool’s capacity. Check the pool’s available

capacity and expand the pool as needed.

Use the following formula to calculate the pool capacity:

Pool capacity = the total capacity of pool-VOLs in the pool - the

management area size of the pool-VOL with the system area

Adding pool-VOLs to pools to expand pool capacity moves data to the added space on a per-page

basis which rebalances the usage rate among parity groups of the pool-VOLs.

CAUTION: Moving existing data to the added space on a per-page basis can decrease host

I/O performance.

You can add up to 1,024 pool-VOLs (including volumes already in a pool) to a pool.

Prerequisite: You are currently not decreasing the pool capacity.

1. In the RWC main window, in the resource tree in the Explorer, click Pools > Pools.

2. In the Pools tab in the Pools window, select the check box for the pool to which you want to

add a pool-VOL from the list and then click Expand Pool.

NOTE: You can only increase the capacity for one pool at a time.
