The auxiliary storage manager (ASM) issues this message when a DISCARD ALL is run for the cache of a cached auxiliary storage subsystem.
For a cold start or a quick start, this message is strictly informational: for the first use of the cache: ASM initialization automatically performs a DISCARD ALL for the cache during these starts. If more than one page data set on the direct access storage device (DASD) backs the cache, ASM will issue this message only for the first data set detected.
For a warm start, this message may indicate a problem: ASM performed the DISCARD ALL after a sense subsystem status request to the cache indicated that a DISCARD ALL was required. This DISCARD ALL makes any warm start data in the cache incorrect. The warm start will not be allowed to continue if ASM determines that warm start data may have been lost.
The system continues operation. If warm start data was lost, the system issues message ILR003A to force a quick start.
Reply U to message ILR003A. For a warm start, notify the system programmer.
For a data problem during a warm start, search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center.
