CTT112A unit, jobName, VOLUME volser NOT IN MDB. REPLY Y - DEFINE, E - EXTERNAL, I - IGNORE OR N - action

Explanation: A mount request was issued for a volume (VOLSER) that is unknown to Control-M/Tape. The specified volume is probably not on-site. This message is issued only if the DYNVOL parameter is set to P (Prompt) in the CTTPARM member.

The jobName job waits for a reply.

Corrective Action: Reply with one of the following values:

• Y - Control-M/Tape dynamically defines the volume in its database.
• E - Control-M/Tape dynamically defines the volume in its database. The volume will be marked as External.
• I - This volume and its data sets should be ignored, as if EXPDT=98000 was specified in the JCL. This value is not available for the first volume in a chain and for single volumes which are not part of a chain.
• N - If this is a specific tape request, the job is abended. If this is a nonspecific tape request, the volume is rejected and a new volume is requested.

CTT113A unit, jobName, VOLUME volser IN VAULT vault. REPLY U - USE OR A - ABEND

Explanation: The database indicates that the volume (volser) requested for mounting is in a remote vault, and the mount request is probably a user error.

CTT127I unit, volser, TEMPORARY DATASET (ddName)

Explanation: This information message indicates that a temporary data set is being written on the specified volume.

Corrective Action: Return the volume to the scratch pool right after its use.

CTT128E ddName INVALID EXPDT VALUE expdt. RC: rc

Explanation: An invalid expiration date (EXPDT) was specified in the JCL. Usually this message is caused by setting EXPDT to 970 xx, which is not supported by Control-M/Tape.

The variables in this message are:

• ddName - the DD statement that contains the invalid date
• expdt - the invalid expiration date
• rc - the return code

Possible values for rc are:

• 4 - expiration date type not supported
• 16 - expiration date in an invalid format, such as
• nonnumeric
• yy000
• yyyy/000

The EXPDT value is ignored and the data set is given a default retention.

Note:

The EXPDT value is expressed in internal format.

Corrective Action: No action is required.

CTT129I unit, VOLUME volser IN {LOCAL VAULT: vaultName, SLOT: slotNumber| OUT LOCATION: loc }

Explanation: This information message indicates that the tape requested for mounting (volser) is located in the specified location.

Corrective Action: No action is required.

CTT130E unit, VOLUME volser NOT IN MDB

Explanation: The specified volume is not defined in Control-M/Tape's Media database. Possible causes are:

• Dynamic Volume Definition is disabled (DYNVOL is set to N in the CTTPARM member).
• N (Abend) reply to message CTT112A.

Corrective Action: Specify EXPDT=98000 in the JCL, or define the volume in the Media database using CTTDLD utility, and rerun the job.

CTT131W unit, VOLUME volser IN USE BY JOB jobName

Explanation: The indicated volser is marked in use by the specified job. Possible causes are:

• A system or program crash left the 'in use' indicator turned on. This occurs when a data set being written does not go through a complete CLOSE process. In this case, the volume remains 'in use'. For example, in the case of a system abend 837, when a demount has occurred for a multi-volume data set but a new mount is disallowed because the file is on more than the maximum number of volumes, a full CLOSE will not occur, and the volume remains 'in use'. In most cases, a cancel command will cause CLOSE processing to occur, but it depends on exactly when the job was canceled. The IEC205I message in the job log will indicate that the job went through a full CLOSE process.
• During online stacking processing, the 'in-use' bit is temporarily set to prevent other jobs from allocating the volume while online stacking is examining the specific volume.

Corrective Action: Do the following:

• To reset this bit, run the CTTIDB utility in repair mode.
• Then run the CTTMUP utility to perform the repair.

CTT132E unit, EDM TRYING TO WRITE ON NON-EDM VOLUME volser

Explanation: An EDM (External Data Manager) is trying to write a data set on a non-scratch volume which is not marked as an EDM Volume. An EDM can only write data on scratch volumes afterwards marked as EDM Volumes, or non-scratch volumes already marked as EDM Volumes.

The job is abended.

Corrective Action: Check the rules regarding EDM. Verify that they have not been changed in a way that caused this problem.

CTT133E unit, NON-EDM TRYING TO WRITE ON EDM VOLUME volser

Explanation: A job that is not an EDM (External Data Manager) is trying to write on a volume that is marked as an EDM Volume. Only an EDM is allowed to write on volumes that are marked as EDM Volumes.

The job is abended.

Corrective Action: Correct the job and rerun.

CTT134A unit, jobName, CONTROL-M/TAPE ENVIRONMENT DOES NOT EXIST. REPLY A - ABEND, R - RETRY OR U - CONTINUE

Explanation: A job is trying to process data on tape, while the Control-M/Tape real-time environment does not exist or is still initializing. Control-M/Tape real-time environment is started by the CTTINIT procedure. No tape processing is allowed while Control-M/Tape is down, unless Control-M/Tape MVS intercepts are disabled.

The job waits for a reply.

Corrective Action: Reply with one of the following values:

• A -- Abend this job.
• R -- Retry to find Control-M/Tape environment. This option enables you to start CTTINIT and then reply Retry.
• U -- Bypass Control-M/Tape for the processing of this data set. In this case, Control-M/Tape does not record or protect any information affected by this job while processing this data set.

CTT135A unit, jobName, 98000 REQUEST FOR MDB VOLUME volume, REPLY ‘U’ - IGNORE, ‘A’ - ABEND OR ‘F’ - FORCE

Explanation: A job specified EXPDT=98000, Control-M/Tape bypass, for a controlled volume. Specifying EXPDT=98000 for a controlled volume is not recommended, because Control-M/Tape cannot enforce data integrity.

The job waits for a reply.

Corrective Action: Reply with one of the following:

• U -- Continue. Ignore the bypass request.
• A -- Abend the job.
• F -- Bypass Control-M/Tape for processing of this data set. In this case, Control-M/Tape does not record or protect any information affected by this job while processing this data set.

CTT136E unit, volser MARKED IN AN OUT LOCATION

Explanation: The operator mounted a volume marked “out of the library” in response to a request to mount a scratch tape.

The volume is rejected. The operator is prompted to mount another volume.

Corrective Action: Mount a scratch tape.

CTT137S CSECT IN ERROR csect, EP: add OFFSET: offset

Explanation: An abend occurred in one of the Control-M/Tape real-time environment modules. This message identifies the CSECT in the module, its Entry Point, and the offset of the error. This message follows message CTT117S.

The job abends.

Corrective Action: Notify BMC Customer Support.

CTT138W unit, DATASET BYPASSED. REASON: rsn VOLUME: volser

Explanation: Control-M/Tape is bypassing the data set on the specified volume. As a result of this bypass, no information regarding this data set is recorded in the MDB.

Valid values for rsn are:

The job continues without Control-M/Tape involvement.

Corrective Action: No action is required.

CTT139I unit, VOLUME volume DYNAMICALLY DEFINED

Explanation: The specified volume was dynamically defined in the Media Database by Control-M/Tape. This volume was not known to Control-M/Tape before this job. The DYNVOL installation parameter determines whether or not such volumes will be defined dynamically.

The job continues.

Corrective Action: No action is required.

CTT140E unit, SPECIFIC REQUEST FOR SCRATCH VOLUME volume DENIED (ddName)

Explanation: A job attempted to access a scratch volume by specifying the volser of this volume. The SCRPROT Installation parameter determines whether a scratch volume is protected from specific access. This message may occur when VOL=REF= value is specified, or when a double open occurs in the same step that acts as a specific request, even though the JCL was for a nonspecific request.

The job is abended.

Corrective Action: Change the JCL as required. If a scratch volume is required, remove the parameter VOL=SER= value or VOL=REF= value.

CTT141E unit, RECREATE ON WRONG VOLUME vol

Explanation: A job attempted to recreate a data set that already exists on the vol volume, but the data set does not start on the volume. Data sets can only be recreated on the same volumes they were on before, and in the same order.

The job is abended.

Corrective Action: Change the JCL as required.

CTT142I IA= instruction_addr SVCA= svc_addr COMP CODE= complected

Explanation: This information message supplies additional details relating to the abend that occurred, and may be accompanied by additional messages.

The variables in this message are:

• instruction_addr -address of the abend
• svc_addr - Control-M/Tape real-time environment module address
• complCode - abend code

Corrective Action: Look for previous error or warning messages.

CTT143E jobName, TASK IS ABENDED BY CONTROL-M/TAPE (rsn)

Explanation: Control-M/Tape abended the jobName task. The cause of the abend is explained in a message that precedes this message, which is indicated by the value of rsn.

The following are the possible values of the reason code (rsn), and the related preceding message for each:

The task is abended. Control-M/Tape does not record any information on this tape data set.

Corrective Action: Do one of the following:

• If rc = 56, increase the region size.
• If rc = 180, stop the earlier version of Control-M/Tape, and rerun the 6.0.01 or later version of the utility.
• If rc = 228, note the contents of the job log and contact BMC Customer Support.
• In all other cases check the preceding message to understand why this message was issued, and proceed accordingly.

CTT144E unit, CONTROL-M/TAPE WAS NOT ACTIVE WHEN JOB STARTED

Explanation: Either Control-M/Tape was not active when the job started to run, or Control-M/Tape was brought down and up while the job was running. If there is any tape activity in the system, Control-M/Tape must be active.

The job is abended, unless Control-M/Tape is in Test mode.

Corrective Action: Rerun the job when Control-M/Tape is active.

CTT145E unit, ACCESS DENIED TO {VOL: volser| DS: dsn }

Explanation: Permission to access the specified volume or data set was denied by the Control-M/Tape security exit.

The job is abended.

Corrective Action: If you think you should have access to this volume or data set, contact your security administrator.

CTT146I unit, JOB CONTINUES DUE TO TEST MODE (rsn)

Explanation: This information message indicates that a job that probably would have abended in PROD or PHASED mode continues processing because the job is running in TEST mode. The cause of the abend is explained in a message that precedes this message, which is indicated by the value of rsn.

The following are the possible values of the reason code (rsn) and the related preceding message for each:

The job continues processing, but Control-M/Tape does not record any more information related to the job.

Corrective Action: No action is required.

CTT147W unit, VOLUME volser MARKED DELETED. JOB CONTINUES

Explanation: The specified volume is marked as deleted might be a physically damaged volume.

Since the job specifically requested this volume, the job continues.

Corrective Action: Check why the volume is marked as deleted, and determine if you want the job to continue processing.

CTT148E unit, RECREATE DISABLED BY INSTALLATION PARAMETERS (ddName)

Explanation: An attempt was made to recreate a data set, and N was specified for the RECREATE installation parameter in the CTTPARM member.

The job is abended.

Corrective Action: If you wish to enable recreation of data sets, contact your INCONTROL administrator.

CTT149E unit, jobName, BYPASS ATTEMPT ON MDB VOLUME volser [{SCRATCH | ACTIVE},{R | W}]

Explanation: Job (jobName) tried to access a volume from the Media Database (MDB), while under a Control-M/Tape bypass. Control-M/Tape bypassed the first volume that the executing task accessed, because it was not in the MDB. When the executing task tried to access a later volume that was in the MDB, Control-M/Tape disabled access by the executing task to the volume, and issued this message.

For security reasons Control-M/Tape requires that when DYNVOL is set to I, if the first volume accessed by the task is not in the MDB, the rest of the volumes accessed by the task must not appear in the MDB either.

This message is issued when:

• The DYNVOL parameter is set to I in CTTPARM, or User Exit 4 (Dynamic Definition exit) selected DYNVOL set to I;
• The first volume accessed by the executing task is not in the MDB, and any volumes that the executing task accesses later are in the MDB.

The system action depends on how the volume was requested.

• If the task requested this specific volume, the task is abended.
• If the volume was mounted in response to a nonspecific mount request, it is rejected, and another scratch tape is requested instead.

Corrective Action: Do one of the following, depending on how the volume was requested.

• If this is a request for this specific volume, verify that all or none of the volumes to be accessed are defined in the MDB.
• If this is a nonspecific tape request, either mount a non-MDB volume, or have the job restarted using only MDB volumes.

CTT150A unit, jobName, CONTROL-M/TAPE ENVIRONMENT IS SUSPENDED. REPLY A-ABEND, R-RETRY OR B-BYPASS

Explanation: A job attempted to process data on a tape, while the Control-M/Tape real-time environment was suspended. The Control-M/Tape real-time environment was suspended by the MODE=SUSPEND statement in the CTTINIT procedure. While Control-M/Tape is suspended, no tape activity is allowed.

The job waits for a reply.

Corrective Action: Specify one of the following operator responses:

• A - Abend the job or task.
• R - Recheck the status of the real-time environment. This enables you to reset Control-M/Tape to status ACTIVE using statement MODE=RESUME in the CTTINIT procedure, before specifying this operator response. Before resetting the status of Control-M/Tape, determine why SUSPEND mode was requested and whether or not you can reset the mode at this time.
• B - Bypass Control-M/Tape for the processing of this data set. In this case, Control-M/Tape does not record or protect any information affected by this job while processing this data set.

CTT151I unit, VOLUMES volser1, volser2 CHAINED ON INPUT

Explanation: This information message indicates that a job successfully read a data set that spans volumes volser1 and volser2, but volume volser2 was a scratch tape.

Control-M/Tape automatically changes the status of the scratch tape (volser2) to ACTIVE and updates the necessary pointers in the volume record so that volser2 is joined in a multivolume chain to volser1.

Corrective Action: No action is required.

CTT152W unit, VOLUMES volser1, volser2 ARE NOT FROM THE SAME GROUP

Explanation: A job is reading a data set from volumes volser1 and volser2 as if they belong to the same volume group. However these volumes are recorded in the Media Database as belonging to two different multivolume chains. The information recorded in the Media Database might not reflect the real status of the two volumes.

This error message may also occur while running Control-M/Tape in TEST mode, as a result of differences between Control-M/Tape and the other tape management system.

The job continues processing.

Corrective Action: Check the volumes specified in this message (volser1 and volser2) and their definitions in the Media Database to determine why this message was issued.

CTT153E unit, MOUNT REQUEST FOR VOLUME volser RECEIVED A VOLUME WITH SL-NAME slName1 WHERE slName2 EXPECTED

Explanation: The SL-NAMEs on the mounted tape (slName1) is different from the one listed in the Media Database for this volser (slName2). Probably a different tape from the one requested was mounted.

The tape is rejected.

Corrective Action: Mount the requested tape. The volser specified in this message should appear on the gummed (external) label.

CTT154I unit, RESTART IN PROGRESS FOR VOLUME volser

Explanation: This information message indicates that the job in process was restarted from volume volser by means of the MVS/RESTART feature.

Corrective Action: No action is required.

CTT155E unit, RESTART FAILED, SELECT A-ABEND, B-BYPASS

Explanation: During tape processing done under MVS/RESTART, Control-M/Tape encountered errors. Since MVS/RESTART is in process, the current status of the volumes or data sets may be different from the status expected by Control-M/Tape.

The errors encountered are described in the messages that precede this message.

The job waits for a reply.

Corrective Action: Reply with one of the following:

• A - Abend the job or task.
• B - Bypass Control-M/Tape for the processing of this data set. In this case, Control-M/Tape does not record or protect any information affected by this job for while processing this data set.

CTT156W unit, {IOA FUNCTIONS | SMS RULES} PROCESSING IS INHIBITED

Explanation: Control-M/Tape can no longer process IOA functions or SMS rules, due to a problem described in the messages preceding this message. IOA functions mentioned in the message refer to DO statements that call IOA functions, for example, DO COND, DO RESOURCE and DO SET.

The job continues without using the specified feature , which is IOA functions or SMS rules.

Corrective Action: Check preceding messages for the reason for this error and correct the problem accordingly.

CTT157W unit, AUTOMATIC CARTRIDGE LOAD DISABLED (n CONSECUTIVE REJECTS)

Explanation: Tapes mounted on the specified unit after a nonspecific mount request, were rejected n consecutive times. Control-M/Tape found that the mounted tape did not satisfy the request requirements. For example, the tape may not be from the requested scratch pool. As a result, it rejected the tape, and issued the mount message again. This process repeated itself n times, after which Control-M/Tape stopped the automatic load process on the specified unit.

Control-M/Tape disables the automatic load process for the specified unit until a tape that satisfies the mount request requirements is mounted manually.

Corrective Action: Have the operator mount tapes that satisfy the mount request requirements.

CTT158E unit_addr, DENSITY OF VOLUME volser IS NOT COMPATIBLE WITH THE DEVICE

Explanation: Volume volser that was mounted for output on unit_addr has a density that is not compatible with the device. This message is issued only when CNGDENS is set to Y in CTTPARM.

The specified volume is currently recorded with a density lower than the density about to be used by the device (for example, a 3480 volume mounted for output on a 3490E device). When CNGDENS is set to N in CTTPARM, Control-M/Tape allows higher density recording on the volume, making it no longer usable on lower density devices. However, since CNGDENS was set to Y in CTTPARM, Control-M/Tape does not allow higher density recording on the volume.

The volume is rejected from the device and a mount message is issued.

Corrective Action: Mount a scratch volume with a compatible density.

CTT159W jobName, PROCESS STOPPED DUE TO {CANCEL | DETACH | ABEND IN ANOTHER TASK}

Explanation: A task was running under the Control-M/Tape real time environment module, and Control-M/Tape needed to stop execution of the task. The reason is one of the following:

• CANCEL - The job was canceled.
• DETACH - A different task caused the Control-M/Tape task to DETACH.
• ABEND IN ANOTHER TASK - A different task abended, and therefore the Control-M/Tape task abended as well.

Corrective Action: If the reason is CANCEL, ignore the message. Otherwise, use the dump to understand which task abended, since Control-M/Tape is not the reason for the abend.
