A fan pack has been shut down or removed from the system. A VSC (power supply unit) has been shut down or removed from the system. A chassis overtemperature condition has been detected, and the SP will attempt corrective action. The logical disk unit of which this disk module is a member has been shut down and can no longer be accessed by the host. A fatal firmware (SP microcode) error occurred; as a result, the microcode reloaded and restarted the SP. This message is logged after the restarted session completes its initialization. Some hardware condition has caused the SP to disable the cache. The problem might be: • BBU is not ready (not present and fully charged) • One or more vault disks is missing or being rebuilt • Fan fault occurred • SP failed A fault occurred but the SP cannot dump the cache to the vault drives, most likely because two or more cache vault disks are missing or have failed. The SP cannot assign this unit, because it is marked as having cached data outstanding, and the controller has no access to the data. A hardware or software failure occurred when the SP attempted to initialize a new cache image. This SP is incapable of loading the saved cache data image due to insufficient cache memory size. The Battery Backup Unit in this disk array has failed or been removed. The Battery Backup Unit in this disk array has failed its internal self-test. A nonmirrored cache recovery was attempted but failed to recover the cache pages for some cached LUNs. It does not apply to a disk array with two SPs. 6-46 Unsolicited Event Log
