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, 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.
