Message Description Recommended Action
Loose cable
detected—
logical drives
may be marked
FAILED until
corrected
Controller unable to communicate
with one or more physical drives,
probably because of a cabling
problem. Logical drives may be in a
FAILED state until the condition is
corrected, preventing access to data
on the controller.
Check all controller and drive cable
connections.
Mirror data
miscompare
Data was found at reinitialization in
the posted write memory; however,
the mirror data compare test failed
resulting in data being marked as
invalid. Data loss is possible.
Replace the Array Accelerator board.
No configuration
for accelerator
board
The Array Accelerator board has not
been configured.
If the Array Accelerator board is present, run the
Array Configuration Utility (ACU) to configure the
board.
NVRAM
configuration
present,
controller not
detected
Nonvolatile RAM has a configuration
for an array controller, but there is no
board in this slot. Either a board has
been removed from the system or a
board has been placed in the wrong
slot.
Place the array controller in the proper slot or
run the System Configuration Utility to
reconfigure nonvolatile RAM to reflect the
removal or new position.
RIS copies
between drives
do not match
Drives on controller contain copies of
RIS which do not match.
Upgrade ADU to most recent version.
SCSI Port x Drive
ID x has
exceeded
threshold(s)
Monitor and performance threshold
for this drive has been violated.
Check for the particular threshold that has been
violated.
SCSI Port x Drive
ID x is not
stamped for
monitoring
Drive has not been stamped with
monitor and performance features.
Run the Array Configuration Utility (ACU).
Changing the configuration and saving should
cause ACU to stamp drive with monitor and
performance features. To do this without
destroying the current configuration, change
Array Accelerator size and save configuration.
Change the Array Accelerator back to original
size and save again.
SCSI Port x Drive
ID x RIS copy
mismatch
Copies of RIS on drive do not match. Drive may need to be replaced. Check for other
errors.
SCSI Port x Drive
ID x failed—
REPLACE (failure
message)
ADU found a drive that needs to be
replaced.
Replace drive or correct condition that caused
error.
SCSI Port x Drive
ID x firmware
needs upgrading
Drive firmware is below
recommended version.
Run Options ROMPaq to upgrade drive to latest
firmware revision.
