Recovering an overflowed user auxiliary storage pool

Reset a user auxiliary storage pool (ASP) in overflowed status as soon as possible. An overflowed ASP affects system performance. It also makes recovery more difficult and might increase the amount of data that is lost if a failure occurs.

When the disk units allocated to a user ASP become full, the user ASP is in overflowed status. The system sends message CPI0953 to the QSYSOPR message queue warning you that an ASP is approaching its storage threshold. The system sends a message CPI0954 when the storage threshold is exceeded and the ASP is in overflowed status.

To recover an overflowed user ASP, follow the procedures in the Resetting an overflowed user auxiliary storage pool (ASP) without an initial program load (IPL) topic.
