-23 MESSAGE 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.
-24 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,
