MACHINECHK, machine check while in kernel mode

Facility: BUGCHECK, System Bugcheck
Explanation: The OpenVMS software detected an irrecoverable hardware error. Because of the severity of the error, further operation is impossible or could corrupt user data. 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.

MAKEWSLE, make working set list entry error

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.

MAPCNTZER, attempted to generate zero length map pointer

MAPHDRBAD, storage map header is bad; volume locked

Facility: MOUNT, Mount Utility
Explanation: An I/O error is encountered during a mount operation, or the header is corrupted. Existing files on the volume can be accessed, but other operations (for example, create and delete) are not possible.
User Action: Copy the files that are still accessible to a new volume. Reconstruct, as necessary, from backup media.

MARKUNL, exec image is marked for unload

Facility: LOADER, Executive Image Loader
Explanation: A call was made to the LDR$UNLOAD_IMAGE 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 Digital.

MAXDEV, too many devices

Facility: MOUNT, Mount Utility
Explanation: Too many devices were specified for a MOUNT operation. For tape devices the limit is 16, for volume sets the limit is 256, and for shadow set members the limit is 3.
User Action: Correct the command and reenter it.

Facility: Cluster Port Driver
Explanation: The maximum number of ports capable of load sharing has been exceeded. The extra ports will not be used in load sharing activities.
User Action: None.

MAXLAB, too many volume labels

Facility: MOUNT, Mount Utility
Explanation: More than 256 labels were specified in the MOUNT command.
User Action: Correct and reenter the command.

MAXLINKS, maximum links already defined

Facility: LAT, LAT Facility
Explanation: The link cannot be created because the maximum number of allowable links is already defined.
User Action: None.

MAXSERV, maximum number of services exceeded

Facility: LAT, LAT Facility
Explanation: An attempt was made to create more than 255 services on the local node.
User Action: A service must be deleted in order to add one.

MAXTOOBIG, maxunits specified is too large

Facility: SYSGEN, System Generation Utility
Explanation: The /MAXUNITS qualifier, as specified, causes an overrun in a word-sized length field when the length of the IDB is calculated.
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 exceeds the maximum allowed (225).
User Action: If this error can be reliably reproduced, contact a Digital support representative.

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.

Message Free Queue Insert Failure
Facility: Cluster Port Driver
Explanation: The port driver attempts to reinitialize the port; after 50 failed attempts, it marks the device off line. This error is caused by a failure to obtain access to an interlocked queue.

User Action: None.

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

Facility: BACKUP, Backup Utility
Explanation: The specified volume is mounted with the /FOREIGN qualifier. However, for the given operation, the volume must be mounted without the /FOREIGN qualifier.
User Action: Reevaluate the operation, checking that the correct I/O devices have been specified and that the /SAVE_SET, /PHYSICAL, and /IMAGE qualifiers are properly used. Then, if appropriate, mount the specified volume without the /FOREIGN qualifier, and reenter the command.

MOUNTFOR, 'device' must be mounted /FOREIGN

Facility: BACKUP, Backup Utility
Explanation: The specified volume is mounted without the /FOREIGN qualifier. However, for the given operation, the volume must be mounted with the /FOREIGN qualifier.
User Action: Reevaluate the operation, checking that the correct I/O devices have been specified and that the /SAVE_SET, /PHYSICAL, and /IMAGE qualifiers are properly used. Then, if appropriate, mount the specified volume with the /FOREIGN qualifier, and reenter the command.
