Description
ADU found loose cable. If logical
drives are marked FAILED, they will
be unusable until the problem is
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.
Data was found at reinitialization in
the posted write memory. However,
the mirror data compare test failed,
resulting in data marked as invalid.
Data loss is possible.
The array accelerator board has not
been configured.
EISA 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.
Drives on controller contain copies of
RIS that do not match.
Monitor and performance threshold
for this drive has been violated.
Drive has not been stamped with
monitor and performance features.
Copies of RIS on drive do not match.
Recommended Action
Turn off the system. Check cables for tight
connection to logical drives. Restart the system.
If the same message recurs, cables may be
bad.
Check all controller and drive cable
connections.
Replace the array accelerator board.
If the array accelerator board is present, run the
ACU)to configure the board.
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.
Upgrade ADU to the most recent version.
Check for the particular threshold that has been
violated.
Run the ACU. Changing the configuration and
saving should cause ACU to stamp the drive
with monitor and performance features. To do
this without destroying the current
configuration, change the array accelerator size,
and save the configuration. Change the array
accelerator back to the original size, and save
again.
Drive may need to be replaced. Check for other
errors.
