routine to unload a removable executive image that already has an
outstanding unload request against it.
User Action: None.
MAXBAD, bad block table overflow for 'device-name'
Facility: BACKUP, Backup Utility
Explanation: The specified volume has too many bad
blocks; either the DCL command INITIALIZE cannot initialize the volume,
or the Backup utility cannot process the volume. This message generally
indicates that the disk volume can no longer be used.
User Action: Check the status of the device and
reenter the command. If the failure persists, reformat the disk. Notify
the system manager. If the failure still persists and the disk pack is
under warranty, return it to Compaq.

User Action: Reenter the SYSGEN command CONNECT with a
smaller /MAXUNITS number.
MAXUNITS, unit number greater than maximum units specified
Facility: SYSGEN, System Generation Utility
Explanation: In creating the I/O database, a unit
number is encountered that is larger than the maximum number of units
allowed (default = 8).
User Action: Retry the operation using the /MAXUNITS
qualifier on the SYSGEN command CONNECT.
MAXVOLS, too many volumes in volume set 'device-name'
Facility: BACKUP, Backup Utility
Explanation: The volume set count recorded in the home
block of relative volume 1 of an input volume set is greater than 255.
Possibly, this value has been corrupted. The Backup utility cannot
process the volume.
User Action: Reconstruct the volume set from backup
media.
MAXVOLS, volume set has too many volumes to handle
Facility: RBLD, REBUILD Command (Mount Utility)
Explanation: The number of volumes in the volume set

Memory dump complete after 'nn' write error(s)
Facility: BUGCHECK, System Bugcheck
Explanation: The memory dump is finished; however,
there are one or more write errors.
User Action: When the system reboots, copy the dump to
another file. Determine the text associated with the hexadecimal status
of previous messages by using the /STATUS qualifier with the DCL
command HELP/MESSAGE or by using the F$MESSAGE lexical function or an
equivalent. If the status indicates a possible disk problem, see the
user action for the accompanying message.
Memory dump incomplete - dump file 'nn' blocks too small
Facility: BUGCHECK, System Bugcheck
Explanation: The system is unable to write out the
remaining 'nn' pages of a complete, physical memory dump (SYSGEN
parameter DUMPSTYLE set to 0). The dump cannot be used because analysis
depends on the system page table, which is kept in the uppermost
physical pages of memory (that is, the last data to be written if this
style of dump is written).
User Action: If there is room on the volume that holds
the system dump file, expand the dump file. If space is limited, try to
write a selective dump. Refer to the OpenVMS System Manager's Manual for the correct
procedures.

MOUNTERR, volume 'volume' on 'device' was not mounted because 'reason'
Facility: BACKUP, Backup Utility
Explanation: The Backup utility was unable to mount
the specified volume for one of the following reasons:
- The expiration date specified in the volume label is in the
future. That is, the data on the volume has not expired.
- The volume label does not match the one requested. The label
specified in the BACKUP command (either explicitly or implicitly) does
not match the label on the volume.
- The volume is protected against access. The protection specified in
the volume header disallows access by the person entering the BACKUP
command.
User Action: At this point, the Backup utility allows
you to either quit the operation, overwrite the volume label and
continue, or put a new volume in the drive and continue processing. To
abort the operation, enter the QUIT command at the BACKUP> prompt.
To overwrite information in the volume header and continue processing,
