(Subsystem 198)

CS80_UNIT_AVAILABLE A multi-unit disk device has notified the host system that a disk unit that was previously locked by another host system has now been unlocked, and is now available for use.

The host system receiving this status had previously attempted to access a unit that was locked by another host system. That attempted access was rejected due to the unit lock imposed by the other host system. The lock has been removed.

Since MPE/iX does not yet support multi-unit disk devices, the host system should never receive this notification. If it does, either a hardware error or system software error has occurred. Call your Hewlett-Packard representative.

CS80_LOST_SPINDLE_SYNCH A multi-mechanism disk controller has detected that the mechanisms within the device are no longer rotationally synchronized within the specified tolerance.

Some hardware problem within one or more of the disk mechanisms is causing the spindle synchronization circuitry to lose synchronization lock.

Continue to use the disk. It will operate correctly even if spindle synch is lost. Its speed of operation will be somewhat reduced. Call your Hewlett-Packard Representative to discuss the problem further.

CS80_MECHANISM_SKIPPED A multi-mechanism disk array device controller has detected that one of the "striped with parity" disk mechanisms is UNASSIGNED: present, not broken, but not part of a logical unit. The "skipped" mech is not being used by the device.

A mechanism has been physically removed and replaced with another mechanism, or the disk diagnostic program has issued a Set Skip Drive command, and, in either case, the disk's REBUILD operation has not yet been performed.

Use the FLEXDIAG diagnostic program to perform a REBUILD operation on the disk device. After successful REBUILDing, the mechanism that was being skipped will no longer be skipped: it will be assigned to the striped logical unit.

CS80_STRIPED_XOR_ERROR A multi-mechanism disk array device controller has detected an XOR Error on a Read Data operation on a Striped With Parity disk device. The parity computed from the striped data did not match the parity stored on the Data Protect disk.

1) Failure to properly format a Striped With Parity disk device. 2) Reading data from an area of the disk media that had not been completely written.

Call your Hewlett-Packard Representative.

CS80_UNKNOWN_HW_STATUS_CLASS The hardware status from the disk device could not be recognized by the system software because the value of the first byte of status (the "status class") was not one of the legal values defined for the device.

Hardware problem in the disk device or in the cabling or interfaces between the disk device and the host system.

Call your Hewlett-Packard Representative.

CS80_UNKNOWN_HARDWARE_ERR The hardware status from the disk device could not be recognized by the system software because the value of the second byte of status was not one of the legal values defined for the Hardware Error status class.

Hardware problem in the disk device or in the cabling or interfaces between the disk device and the host system.

Call your Hewlett-Packard Representative.

CS80_UNKNOWN_RESOURCE_ERR The hardware status from the disk device could not be recognized by the system software because the value of the second byte of status was not one of the legal values defined for the Resource Error status class.

Hardware problem in the disk device or in the cabling or interfaces between the disk device and the host system.

Call your Hewlett-Packard Representative.

CS80_UNKNOWN_COMMAND_ERR The hardware status from the disk device could not be recognized by the system software because the value of the second byte of status was not one of the legal values defined for the Command Error status class.

Hardware problem in the disk device or in the cabling or interfaces between the disk device and the host system.

Call your Hewlett-Packard Representative.

CS80_NO_SELFTEST_PERFORMED The disk array controller on a disk array device that is a "link device" (i.e. is directly connected to the host system by fiber-optic cable) has rejected a device-wide selftest command that was issued by the host system.

Diagnostic program software error. Diagnostic programs should not issue device -wide selftest commands to disk array devices when they are "link devices". The disk array controllers are designed to reject such commands.

Check to see that the diagnostic program is being run correctly. If it is, and this error persists, call your Hewlett-Packard Representative.

CS80_CONFIGURATION_FAULT During a device power-on selftest, the disk array device controller could not satisfy the device configuration (operating mode) that was specified by the settings of the device's front-panel configuration switches.

Device installation error or hardware failure. Either the configuration switch settings are wrong, or the drive modules are wrongly located in the disk array module slots, or one or more drive modules have failed.

Check for and correct improper configuration switch settings or drive module placements. Check for failed drive modules. If none of these checks reveal and correct the problem, then call your Hewlett-Packard representative.

CS80_FIRMWARE_UPGRADE_MODE A host system has issued a transaction to a disk array device at a time when the device cannot perform the transaction, due to a lack of operational firmware in the disk array device controller.

The host system, under diagnostic program control, attempted to upgrade the controller firmware in the disk array device controller (by downloading new firmware), and that upgrade operation did not complete successfully.

Call your Hewlett-Packard Representative.

CS80_TOO_MANY_SPARES The disk device controller has rejected a SPARE BLOCK command issued by the host system. The command was rejected because ten or more SPARE BLOCK commands had already been given to the device since it was last powered-on.

Probably a hardware problem in the disk device has been causing the disk device to report an excessive number of Unrecoverable Read errors to the host system, thus causing the host to issue an excessive number of SPARE BLOCK commands.

Call your Hewlett-Packard Representative.

CS80_MECHANISM_FAULT The disk array device controller has detected sufficient error conditions in one of the disk mechanisms to cause the controller to declare the mechanism to be faulty. The controller has removed the mechanism from service.

A mechanism within a disk array device has exceeded its allowable error threshold.

Call your Hewlett-Packard Representative. If this is a Parity-Protected disk array device and this is the only mechanism that has faulted, then the device will continue to operate correctly. If not, the device will go "offline".

CS80_UNABLE_TO_SKIP_MECH CS80 hardware status indicates that the device has received an improper "Set Skip Drive" command from the host system. The command was improper because its execution would have caused the disk unit to "go offline" and be inoperable.

In disk array devices, either a Parity-Protected Striped Unit already has one "skipped" or "faulted" mechanism (and so cannot tolerate another skipped mechanism) or else a Non-Parity-Protected Unit has been asked to skip a mechanism; it can't.

This condition indicates improper operation by or of the host system's disk diagnostic software. Check to see that the diagnostic program is being run correctly. If it is, and the problem persists, call your Hewlett-Packard Representative.

CS80_VIRT_CIRCUIT_IN_USE Disk hardware status indicates that the device received a new command that used the same Virtual Circuit Number as a previous command that is still executing.

Possible intermittent problem in disk hardware, cabling or interface hardware, or a system software error.

If the problem persists, take a system dump, and call your Hewlett-Packard Representative.

DISK ARRAY HAS DISABLED A MECHANISM IN LDEV #. NOW IN DATA RECOVERY MODE. NO DATA LOST OR CORRUPTED. OPERATION MAY CONTINUE. PLEASE PLACE SERVICE CALL SOON.

A mechanism in the disk array has suffered a failure. The disk array is in data recovery mode and no immediate action need be taken on the part of the user.

This message will be repeated on the console once a minute until the operator acknowledges that he has seen it by replying 'yes' to it. A service call should be placed in the near future.

ACKNOWLEDGE DISABLED MECHANISM IN DISK ARRAY IN LDEV #

This is the acknowledgement message which corresponds to the repeating message regarding the disabled mechanism in the disk array.

This message must be replied to (Y) in order to stop the repeating message.
