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, enter the OVERWRITE command at the BACKUP> prompt. To restart the operation with a new volume, enter the NEW command at the BACKUP> prompt. If the QUIT or NEW command is chosen, the Backup utility automatically dismounts the volume.

> MOUNTF11, 'file-spec' must be mounted Files--11
