Chapter 67 ODP (Optical Disk Process) Messages

Cause  The optical disk process has detected a bad directory file while attempting to bring a volume up (without the COLD option). One of the following has occurred:

Effect  The volume is left down.

Recovery  Bring the volume back up with the COLD option of the Peripheral Utility Program (PUP) UP command.

Cause  The optical disk process has detected an inconsistency between information on a file label and information in the magnetic-disk directory file for a volume. Inconsistent information may be the result of a bad count on the directory read or an illegal file-label address.

Effect  If this error occurs during a file-open operation, file-system error 157 is returned to the calling process and the file is not opened. If this error occurs when a volume is being brought up, the volume is not brought up, but the directory rebuild continues.

Recovery  Bring down the specified volume, purge its old directory file, and bring the volume up using the Peripheral Utility Program (PUP) UP, COLD command to rebuild the file. See Appendix B, for information about the specified error.

Cause  The optical disk process (ODP) has detected an inconsistency between information in the recovery file and other hardware or software information. Inconsistent information may result from one of the following:

Effect  If the error occurs while the entire ODP is being brought up, it is not brought up. If the error occurs while a volume is being mounted into a drive, the volume is brought down.

Recovery  Bring up the ODP or volume with the COLD and SUBVOL options of the PUP UP command.

Cause  The optical disk process (ODP) has detected an inconsistency between information on a volume label and the information in the magnetic-disk directory file for that volume. Inconsistent information may result from one of the following:

Effect  If this error occurs while a volume is being brought up, the volume is not brought up and cannot be used. If this error occurs while a volume is being mounted onto a drive, the volume is brought down and all files are closed.

Recovery  See Appendix B, for information about the specified error. For more detailed information including recovery actions, see the Guardian Procedure Errors and Messages Manual.

Cause  A cartridge is in the carrier, ready to be removed.

Effect  The Peripheral Utility Program (PUP) EJECT operation is finished.

Recovery  A number of hardware or software conditions could cause this message, depending on the error received. Look for obvious hardware problems, such as loose cable connections, a lack of power, or the wrong controller. Check the Tandem Maintenance and Diagnostic System (TMDS) log for related errors or messages and try to determine whether the error is hardware-related or software-related.

If you are unable to determine the cause of the error or to bring up the ODP, contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  After a PUP UP, COLD command, the optical disk process (ODP) detected a cartridge in the specified drive.

Effect   The cartridge is available for use.

Recovery  Informational message only; no corrective action is needed.

Cause  The optical disk process (ODP) is being brought up with the WARM option in the Peripheral Utility Program (PUP) UP command. The recovery file states that a cartridge is in drive #num, but the drive is empty. A cartridge has been physically moved without updating the recovery file.

Effect  If the ! option is used, recovery-file entries for the cartridge are cleared and ODP message 556 (the ODP brought up a volume using the ! option) is generated. If the ! option is not used, the PUP UP operation fails with file-system error 15.

Recovery  See Appendix B, for information on the specified error. To recover from this error, do one of the following:

Cause  A processor switch was initiated, but the ODP encountered an error.

Effect  The ODP is brought down.

Recovery  Try to bring up the ODP using the Peripheral Utility Program (PUP) UP command. If you are unable to bring it up, check the Tandem Maintenance and Diagnostic System (TMDS) log for related errors or messages and try to determine whether the error is hardware-related or software-related.

If you are unable to determine the cause of the error, contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  A processor switch was initiated and ended normally. This error is preceded by optical disk process (ODP) message 522 (a processor switch has occurred).

Effect  The backup processor becomes the primary processor.

Recovery  Informational message only; no corrective action is needed.

Cause  This message can appear after issuing a Peripheral Utility Program (PUP) UP, COLD command. It can be caused by an invalid sector count in a file-label trailer record, by an invalid file label, by a bad file-label trailer record version, or by other file-label problems.

Effect  The PUP UP, COLD operation for a specific volume is abandoned because it is likely that user data has been encountered, or an optical disk process (ODP) internal error has created the appearance of bad data. If the ! option is used, the volume comes up in permanent read-only mode.

Recovery  Use the PUP UP command with the ! option to try to bring up each volume individually. If the volume cannot be brought up or if you need to write to the volume, contact your service provider and provide all relevant information ad follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  After a Peripheral Utility Program (PUP) UP, WARM command, a cartridge could not be located in its designated cell or in a drive if the recovery file said it was there. The ! option is being used, so the cartridge is removed from the recovery file just as it would be removed after a PUP EJECT command. It is possible that the cartridge is still in the jukebox, in another drive. If so, it is added back to the recovery file just as it would be added if the cartridge were inserted into the jukebox.

Effect  The drive is brought up without the missing cartridge.

Recovery  If the cartridge has been removed from the jukebox manually (during maintenance, for example), find the cartridge, reinsert it, and bring up the volumes using the PUP UP command. If you cannot locate the cartridge, there may be a sensor malfunction within the jukebox. Contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  The optical disk process (ODP) has detected a condition that may be caused by the disk I/O slot being left open for an extended period. This message is valid only for the 5410 optical disk storage subsystem.

Effect  The ODP continues to issue this error message until the slot is closed. If the slot is closed, the ODP returns to normal operation.

Recovery  Check the disk I/O slot to ensure that nothing is preventing the shutter from closing. Remove any object that is preventing the shutter from closing and press the IN button to close the shutter.

Cause  A load is pending for multiple cartridges.

Effect  The optical disk process (ODP) has transported multiple cartridges to storage cells.

Recovery  Informational message only; no corrective action is needed. If this message occurs frequently, contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  Multiple cartridges are ready to be removed. This message is valid only for the 5410 optical disk storage subsystem.

Effect  The OUT indicator for the operator panel on the 5410 optical disk storage subsystem lights, prompting you to remove the cartridges that are prepared for ejection.

Recovery  Press the OUT button for the operator panel on the 5410 optical disk storage subsystem and remove each prepared cartridge. See Section 3 of the 5410, 5411, and 5420 Optical Disk Subsystem Manual for information about removing cartridges.

Cause  A single cartridge is ready to be removed.

Effect  On the 5411 and 5420 optical disk storage subsystems, the cartridge is delivered to the disk I/O slot. On the 5410 optical disk storage subsystem, the OUT indicator on the operator panel lights, prompting you to remove the cartridge.

Recovery  On the 5411 and 5420 optical disk storage subsystems, remove the cartridge from the disk I/O slot. On the 5410 optical disk storage subsystem, press the OUT button and remove the cartridge. See Section 3 of the 5410, 5411, and 5420 Optical Disk Subsystem Manual for information about removing cartridges.

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  During a Peripheral Utility Program (PUP) UP, COLD command, a value for the lower free sector bound for a volume is calculated, but there is data at that disk address. This message indicates that data has been written to a volume without a corresponding file label to point to it.

Effect  If the ! option is used, the volume is brought up in permanent read-only mode. If the ! option is not used, the volume remains down and file-system error 157 is returned.

Recovery  Try to bring up the volume using the PUP UP command with the ! option. If you are unable to bring up the volume, or if you want to write to the volume, contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  The optical disk process (ODP) attempted to write to a volume on a write-protected cartridge.

Effect  The write is rejected with file-system error 134. All files open for write access on either volume of the cartridge are closed.

Recovery  To write to either volume, you must remove write protection from the cartridge. See Section 3 of the 5410, 5411, and 5420 Optical Disk Subsystem Manual. See Appendix B, for information on the specified error.

Cause  The optical disk process (ODP) has attempted to write to a volume whose supply of alternate sectors is exhausted.

Effect  The write is rejected with file-system error 134. All files open for write access on the volume are closed.

Recovery  Reset the volume’s access mode to RW using a Peripheral Utility Program (PUP) ALTER command and retry writing to the volume. See Appendix B, for information on the specified error.

Cause  The optical disk process (ODP) has detected an inconsistency in file labels during a Peripheral Utility Program (PUP) UP, COLD command.

Effect  If the ! option is used, the UP, COLD operation continues. File-system error 10 or 11 is returned if no other error is encountered later in processing.

Recovery  If this message appears frequently, contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  The optical disk process (ODP) brought up a volume using the ! option and tolerable errors occurred, for which other ODP messages were generated.

Effect   The following file-system errors can be returned: 10, 11, 120, or 157. The volume is placed in read-only mode. For file-system errors 10, 11, or 120, the file-open mode can be altered for read and write access. For file-system error 157, read-only mode is permanent. The following table shows possible errors and the ODP messages they generate.

Recovery  Informational message only; no corrective action is needed. See Appendix B, for information on the specified error.

Cause  The optical disk process (ODP) subsystem has been powered on or off. This message is valid only for the 5410 optical disk storage subsystem.

Effect  The ODP takes the appropriate recovery action. If unsuccessful, the optical disk storage subsystem is brought down.

Recovery  Informational message only; no corrective action is needed. If the ODP is brought down, contact your service provider and provide all relevant information as follows:

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Cause  The optical disk process (ODP) has written to alternate sectors, and a warning threshold has been exceeded. It is possible that few alternate sectors remain available for use.

Effect  The ODP continues to operate normally.

Recovery  If this message appears frequently, the cartridge may be defective. Try cleaning the cartridge using the procedure described in the WOA-D11 Writable Optical Disk Cleaning Kit Manual. Use the Tandem Maintenance and Diagnostic System (TMDS) ODISK TEST command to analyze the optical media. See Section 6 of the 5410, 5411, and 5420 Optical Disk Subsystem Manual for more information.

If you are unable to determine the cause of the problem, contact your service provider and provide all relevant information as follows:

Cause  A cartridge cannot be read.

Effect  The cartridge is demounted and remounted, if possible, on the same drive or on another drive.

Recovery  If this message appears infrequently, it is an informational message only; no corrective action is needed. If the message appears often, use the Tandem Maintenance and Diagnostic System (TMDS) ODISK TEST command to test the optical drive. See Section 6 of the 5410, 5411, and 5420 Optical Disk Subsystem Manual for more information.

Cause  A cartridge has just been mounted or flipped and its volume label read. The optical disk process (ODP) has discovered that the incorrect volume is now mounted (UP) in the drive.

Effect  The ODP displays the name of the incorrect volume that is mounted and corrects the recovery file accordingly. The user request that caused the mount or flip in an attempt to access the other side of the cartridge is reexecuted.

Recovery  Informational message only; no corrective action is needed.

Cause  The optical disk process (ODP) detected an error during initialization. Such an error could result from a buffer that could not be locked, a segment that could not be allocated, or a configuration parameter that is incorrect or not allowed.

Effect  The ODP is not brought up.

Recovery  Reexamine the CONFTEXT configuration file or the Configuration Utility Program (COUP) commands that you used to configure the ODP. Correct any mistakes you made, and repeat the procedure. If you are unable to bring up the ODP, contact your service provider and provide all relevant information as follows:
