Choosing the procedure to recover user auxiliary storage pools (ASPs)

Here are the basic situations that might require you to recover information in a user ASP.

• You have replaced a disk unit in the system ASP. Although the data is still in your user ASPs, you must recover the system's ability to locate that data (addressability). This process is described in Recovering a basic user auxiliary storage pool (ASP) after recovering the system ASP.
• You have replaced a disk unit in a basic user ASP. All the information that was in the user ASP must be recovered. If this is your situation, follow the procedure described in Recovering a damaged basic auxiliary storage pool.
• You have replaced a disk unit in the system ASP. One of your basic user ASPs was in overflowed status. You must recover the addressability to information in the user ASPs that were not overflowed by using the procedure described in Recovering a basic user auxiliary storage pool (ASP) after recovering the system ASP. You must also recover the information in the user ASP that was overflowed by using the procedure described in Recovering a damaged basic auxiliary storage pool.
• The service representative has replaced a failed disk unit in an independent ASP. When you lose a 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. Follow the procedure described in Recovering an independent auxiliary storage pool.
