CACHBAT

information in the Service Action Log if it is available. If the location is not
available, find the address of the storage IOA. See “SRC Address Formats” on
page 936. Use the address to find the location. See “Locations and Addresses” on
page 705.
If the failing item is in a migration tower, go to the CACHBAT symbolic FRU in
the
