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 63), 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.
