Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE -- COVER LETTER -- Page 2 14 January 2000 - [SYSEXE]SHADOW_SERVER.EXE o When a copy operation that interrupts a merge operation is terminating, it finds that there are no members marked for the merge and the thread crashes the system with a SHADDETINCON bug check. Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o SHOW DEVICES shows zero percent merged status although the shadow set status does not indicate that a merge is required. Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o Bit 16 in SHADOW_SYS_DISK can be set by the user to eliminate using remote members of the shadowset for reads. Occasionally, use of bit 16 fails to eliminate remote members from being used. Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o A CPUSPINWAIT bug check can occur, if the read of the SCB, of a shadow set member, cannot pass the checksum test. Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o DCD (Disk Copy Data) will not always be initiated properly. During an assisted copy operation, if the source member was dismounted or otherwise removed from the shadow set, the connection to the controller would not clean up correctly. Images Affected: -- COVER LETTER -- Page 3 14 January 2000 - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o A full copy operation that is interrupted for a mini-merge will not complete the full copy operation correctly. Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o Typing incorrect commands results in a system crash Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE o When two disks are added to a shadowset in the same mount command, the copies are done sequentially instead of in parallel. This causes the copies to take twice as long as they should. Images Affected: - [SYS$LDR]SYS$SHDRIVER.EXE - [SYSEXE]SHADOW_SERVER.EXE 6 KIT INSTALLATION RATING: The following kit installation rating, based upon current CLD information, is provided to serve as a guide to which customers should apply this remedial kit.
