Troubleshooting Device SCSI Channel Problems Symptom Not all disk drives connected to the controller device channels are displayed during boot, or the controller hangs during display of connected drives. Solution I See Chapter 2, Setting Up Your Storage Subsystem to be sure that the enclosure is properly configured for use with a RAID controller. I Check termination and ID assignment. If you have enabled Ultra/Ultra2 SCSI on any device channels, try disabling it. Problems During Bootup The following sections describe problems you might encounter during Power On Self-Test (POST) or during bootup sequence of the enclosure and explains how to resolve those problems. POST shows problems related to the processor, logic, and memory. Symptom Controller failed the onboard memory test. System hangs at Loading Bridge during BFLU Loader Menu. One of the POST diagnostic tests failed. Solution When this failure occurs, it means the internal CPU memory failed. Replace the controller to correct the problem. Re-flash the firmware to ensure you are using the latest version. Refer to the Disk Array Administrator User's Guide. If you cannot update the firmware or if the updated firmware does not correct the problem, replace the controller. Dual RAID controllers require the same version of firmware on both controllers.

Troubleshooting
Device SCSI Channel Problems
Problems During Bootup
The following sections describe problems you might encounter
during Power On Self-Test (POST) or during bootup sequence of
the enclosure and explains how to resolve those problems. POST
shows problems related to the processor, logic, and memory.
Symptom
Solution
Not all disk drives connected to
the controller device channels are
displayed during boot, or the
controller hangs during display of
connected drives.
■
See
Chapter 2,
Setting Up Your
Storage Subsystem
to be sure that
the enclosure is properly
configured for use with a RAID
controller.
■
Check termination and ID
assignment. If you have enabled
Ultra/Ultra2 SCSI on any device
channels, try disabling it.
Symptom
Solution
Controller failed the onboard
memory test.
When this failure occurs, it means
the internal CPU memory failed.
Replace the controller to correct
the problem.
System hangs at Loading Bridge
during BFLU Loader Menu.
Re-flash the firmware to ensure
you are using the latest version.
Refer to the
Disk Array
Administrator User’s Guide
. If you
cannot update the firmware or if
the updated firmware does not
correct the problem, replace the
controller. Dual RAID controllers
require the same version of
firmware on both controllers.
One of the POST diagnostic tests
failed.
Contact service provider.
