Message Description Recommended Action
WARNING: Storage
enclosure on SCSI
bus X indicated it is
operating in single
ended mode.
SOLUTION: This
usually occurs when
a single ended drive
type is inserted into
an enclosure with
other drive types;
and that makes the
entire enclosure
operate in single
ended mode. To
maximize
performance replace
the single ended
mode drive with a
type that matches
the other drives.
One or more single-ended mode
SCSI drives are installed in an
external storage unit that operates
in low voltage differential (LVD)
mode.
The array is operational, but installing all LVD
drives maximizes performance.
Write memory error Data could not be written to the
cache memory. This typically
means that a parity error was
detected while writing data to the
cache. This could be caused by an
incomplete connection between the
cache and the controller. This is not
a data loss circumstance.
With system powered down, verify that the cache
board is fully connected to the controller.
Wrong Accelerator This could mean that the board was
replaced in the wrong slot or was
placed in a system previously
configured with another board type.
Included with this message is a
message indicating (1) the type of
adapter sensed by ADU, and (2) the
type of adapter last configured in
EISA nonvolatile RAM.
Check the diagnosis screen for other error
messages. Run the server setup utility to update
the system configuration.
