Error messages 84
WARNING - Drive Write Cache is Enabled on X
Description: 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. Condition can cause data corruption if power
to the drive is interrupted.
Action: Replace the drive with a supported drive or restore the operating parameter of the drive.
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 drive with a type that matches the other drives.
Description: One or more single-ended mode SCSI drives are installed in an external storage unit that
operates in LVD mode.
Action: The array continues to operate, but installing all LVD drives maximizes performance.
Write Memory Error
Description: Data cannot be written to the cache memory. This typically means that a parity error was
detected while writing data to the cache. This can be caused by an incomplete connection between the
cache and the controller. This is not a data loss circumstance.
Action: Power down the system and be sure that the cache board is fully connected to the controller.
Wrong Accelerator
Description: This may 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 ("Array Diagnostic Utility" on page 56), and (2) the type of adapter last
configured in EISA NVRAM.
Action: Check the diagnosis screen for other error messages. Run the server setup utility to update the
system configuration.
POST error messages and beep codes
Introduction to POST error messages
The error messages and codes in this section include all messages generated by ProLiant servers. Some
messages are informational only and do not indicate any error. A server generates only the codes that
are applicable to its configuration and options.
HP ProLiant p-Class server blades do not have speakers and thus do not support audio output. Disregard
the audible beeps information if the server falls into this category.
IMPORTANT: This guide provides information for multiple servers. Some information may not apply to the
server you are troubleshooting. Refer to the server documentation for information on procedures, hardware
options, software tools, and operating systems supported by the server.
WARNING: To avoid potential problems, ALWAYS read the warnings and cautionary
information in the server documentation before removing, replacing, reseating, or
modifying system components.
