TAPEALLODIFFF, The TAPE_ALLOCLASS parameter value for the processor
on SCSI bus 'device-name', ID 'slot-number', is different from the value on this system. This condition creates multiple names for the same device, which can lead to data corruption.

Facility: STACONFIG, Standalone Configure Process
Explanation: The value of the SYSGEN tape allocation class parameter differs between the local node and the specified remote node.
User Action: Set the TAPE_ALLOCLASS parameter to the same nonzero value on both nodes.
TAPEALLOZERF, This system and/or the processor on SCSI bus
'device-name', ID 'slot-number', has a zero TAPE_ALLOCLASS value. This condition creates multiple names for the same device, which can lead to data corruption.

Facility: STACONFIG, Standalone Configure Process
Explanation: The local node, remote node, or both nodes have the SYSGEN tape allocation class parameter set to zero.
User Action: Set the TAPE_ALLOCLASS parameter to the same nonzero value for both nodes.
TAPECLASS, fatal error detected by Tape Class driver (TUDRIVER)

Facility: BUGCHECK, System Bugcheck
Explanation: The OpenVMS software detected an irrecoverable, inconsistent condition. After all physical memory is written to a system dump file, the system automatically reboots if the BUGREBOOT system parameter is set to 1.
User Action: Use the BACKUP command with the /IGNORE=NOBACKUP qualifier to make a backup save set of the system dump file and the error log file active at the time of the error. Contact a DIGITAL support representative and describe the conditions leading to the error.
