Recovering a damaged basic auxiliary storage pool

You can use this procedure to recover a damaged basic auxiliary storage pool (ASP).

Perform this procedure if one of the following is true:

• The service representative has replaced a failed disk unit in a basic user ASP. If a disk unit is not parity protected or mirrored, when you lose that disk unit in an ASP, you must recover all of the information in that ASP. The information in other ASPs on your system is not affected.
• The system has reassigned sectors on a disk unit, but object damage has occurred.
• You have replaced a disk unit in the system ASP and one or more user ASPs was overflowed.
