Message 72 CACHE ERROR IGNORE? =YES Type User input 73 CACHE HARDWARE BATTERIES MISSING Error 80 REPLACEMENT DRIVE FOUND BOX # BAY Informational Description Action During power up, data was found in the cache that could not be flushed to the hard drives. The reason is either because the data does not belong to this array controller (the cache module was moved from a different array controller) or the cache data is partial (the rest of the data is in another cache module that was removed from the array controller). This error could occur if cache modules are moved improperly. If = 1.1 or 1.2: There is currently only one cache module in the array controller, but the controller was previously configured with a second cache module that is now missing. If = 2.1 or 2.2: A second cache module was added to this controller, but it contains data from its previous array controller. If = 2.3: The single cache module on this array controller was replaced, but with cache module containing data from a different array controller. Return the cache module to its original array controller, power on the system without allowing any host I/O, and wait for cache data to be written to hard drives. The system can be powered off and the cache module moved to the new location. < = no. The array controller will halt. > = yes. Cache data will be erased and operation of the array controller will continue. The cache module does not have its required batteries attached to it. If the failure occurred on the standby array controller, remove the standby array controller, remove cache, attach cache batteries, replace the cache modules, wait 10 seconds, and then reinsert the array controller, ensuring that it is fully seated in the chassis. If the failure occurred on the active array controller, wait until downtime is available. Power off the MSA, remove the array controller, replace the cache modules, and reinsert the array controller, ensuring it is fully seated in the chassis. Should the issue persist, contact HP support. A SCSI hard drive that was previously missing or failed has now been replaced with a working SCSI drive. maintenance and service guide 47
