REQUESTING MANUAL INTERVENTION ON FAILURE OF INITIAL MICROCODE LOAD ATTEMPTS DURING RECOVERY OF MODIFIED CUSTOMER DATA

摘要

A storage system maintains a cache and a non-volatile storage. An error recovery component queries a cache component to determine whether modified customer data exists in a memory preserve cache. In response to determining that the modified customer data exists in the memory preserve cache, and in response to a failure beyond a threshold number of times of initial microcode load (IML) attempts to recover the modified customer data, an error notification is transmitted for manual intervention to avoid loss of the modified customer data.
