Other Components
The focus of this document is correcting array malfunctions resulting from faulty disk
drives. However, during the process of diagnosis, it is important to remember that any
component is potentially subject to failure. This is particularly true when all of your disk
drives pass a full diagnostic test yet the array still has a problem.
In addition to disk drive failures, the following items could cause an array to become
or go
CRITICAL
OFFLINE
SuperTrak
Damaged or disconnected:
•
Data cable
•
Power cable
Even less common but still possible are:
•
Faulty RAID controller
•
IRQ conflict
Suggestions for Test and Correction
•
Removing a disk drive for testing gives you an opportunity to check its connections.
•
If you have a SuperTrak SX6000, opening your computer gives you a chance to
check all of the disk drive data and power cable connections.
•
If you have an UltraTrak, check the null-modem and SCSI cable connections to your
computer.
•
Cable problems are typically diagnosed by substituting a known-good cable and then
retrying the task that did not work with the original cable.
Note that changing a cable may fix a poor connection. If the known-good cable
works, retest with the original cable to rule out a bad connection.
•
Use the Windows Device Manager to check and adjust IRQs, COM port function and
RAID controller function.
•
Consult the RAID controller documentation for diagnostic procedures and support.
•
If other components are working correctly, the RAID controller may have a
malfunction. Contact Promise Technical Support for further direction.
