ADU Diagnostic Messages
Message
Unknown disable
code
Unrecoverable read
error
WARNING - Drive
Write Cache is
enabled on X
Warning bit detected
Write memory error
Wrong accelerator
continued
Description
A code was returned from the array
accelerator board that ADU does not
recognize.
Read parity errors were detected when
attempting to read same data from
both sides of mirrored memory. Data
loss will occur.
Drive has its internal write cache
enabled. The drive may be a
third-party drive, or the operating
parameters of the drive may have
been altered. This condition may
cause data corruption if power to the
drive is interrupted.
A monitor and performance threshold
violation may have occurred. Status of
a logical drive may not be OK.
Data could not be written to cache
memory. This typically means that a
parity error was detected while writing
data to cache. This could be caused by
incomplete connection between cache
and controller. This is not a data loss
circumstance.
This could mean that either the board
was replaced in the wrong slot or
placed in a system that was previously
configured with another board type.
Included with this message is a
message indicating the type of adapter
sensed by ADU and a message
indicating the type of adapter last
configured in EISA nonvolatile RAM.
Recommended Action
Obtain the latest version of ADU.
Replace the array accelerator board.
Replace the drive with a Compaq supplied
drive or restore the operating parameters
of the drive.
Check the other error messages on the
diagnosis screen for an indication of the
problem.
With power to the system turned off, verify
that the cache board is fully connected to
controller.
Check the diagnosis screen for other error
messages. Run the System Configuration
Utility to update the system configuration.
