879.0. "Lost_data and Corrupt Cache - HSZ50?" by SANITY::PCUMMINGS (The perfect democracy) Thu May 15 1997 16:01

    Does anybody know what causes and how to prevent HSZ50 Corrupt Cache
    conditions and Lost_Data conditions on HSZ HW RAID units?
    
    We saw this show up after 2 new TruClusters were shipped to our site
    and had been working fine at another site.  Several power resets did
    NOT clear these errors.  Wound up doing the following:
    
    CLEAR_ERRORS THIS_CONTROLLER INVALID_CACHE DESTROY_UNFLUSHED_DATA
    
    (Did same for OTHER_CONTROLLER)
    
    CLEAR_ERRORS D0 LOST_DATA
    CLEAR_ERRORS D100 LOST_DATA
    etc.
    
    Anyone?

879.1	Dead (or disconnected) batteries	SSDEVO::JACKSON	Jim Jackson, HSx RAID team	`Fri May 16 1997 09:31`	2
	You'll get that if the cache battery goes dead, and the controller was not cleanly shut down.
