SMAPP and independent disk pools

Use SMAPP to limit recovery time for access paths that reside within independent disk pools.

When you use SMAPP to protect access paths in independent disk pools, you can specify the recovery time individually for each independent disk pool. This helps limit the vary-on duration as well as the quantity of background job activity, which must ensue to make each access path whole when you vary on your independent disk pool after an abnormal vary off.

The recovery time that you specify becomes an attribute of the independent disk pool and thus moves with the independent disk pool if you switch it between systems. Therefore, if you are switching an independent disk pool between systems, you only need to specify the recovery time once.

The only occasion when the specified recovery time is not moved is when the system you are moving the independent disk pool to has its system wide recovery time specified as *OFF. In this case, the independent disk pool's recovery time is set to *NONE when you vary on the independent disk pool.
