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.
CAUSE
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.
ACTION
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.

MESSAGE
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.
CAUSE
Some hardware problem within one or more of the disk mechanisms
is causing the spindle synchronization circuitry
to lose synchronization lock.
ACTION
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.
-25
MESSAGE
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.
CAUSE
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.
ACTION
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.

MESSAGE
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.
CAUSE
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.
ACTION
Call your Hewlett-Packard Representative.

MESSAGE
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.
CAUSE
Hardware problem in the disk device or in the cabling
or interfaces between the disk device and the host system.
ACTION
Call your Hewlett-Packard Representative.
-181
MESSAGE
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.
CAUSE
Hardware problem in the disk device or in the cabling
or interfaces between the disk device and the host system.
ACTION
Call your Hewlett-Packard Representative.
-182
MESSAGE
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.
CAUSE
Hardware problem in the disk device or in the cabling
or interfaces between the disk device and the host system.
ACTION
Call your Hewlett-Packard Representative.
-183
MESSAGE
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.
CAUSE
Hardware problem in the disk device or in the cabling
or interfaces between the disk device and the host system.
ACTION
Call your Hewlett-Packard Representative.
-184
MESSAGE
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.
CAUSE
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.
ACTION
Check to see that the diagnostic program is being run correctly.
If it is, and this error persists, call your Hewlett-Packard
Representative.
-185
MESSAGE
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.
CAUSE
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.
ACTION
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.
-186
MESSAGE
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.
CAUSE
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.
ACTION
Call your Hewlett-Packard Representative.
-187
MESSAGE
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.
CAUSE
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.
ACTION
Call your Hewlett-Packard Representative.
-188
MESSAGE
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.
CAUSE
A mechanism within a disk array device has exceeded
its allowable error threshold.
ACTION
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".
-189
MESSAGE
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.
CAUSE
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.
ACTION
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.
-190
MESSAGE
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.
CAUSE
Possible intermittent problem in disk hardware,
cabling or interface hardware, or a system software error.
ACTION
If the problem persists, take a system dump, and
call your Hewlett-Packard Representative.
