Step 3
Try to boot and run standalone diagnostics against the system, particularly against the
intended boot device. If an SRN is generated, go to the
RS/6000
Eserver
pSeries
Diagnostic Information for Multiple Bus Systems manual.
If diagnostics boot successfully and
″
No Trouble Found
″
was the result when
diagnostics were run against the intended boot device, go to substep 4. If the
diagnostics boot successfully, but the intended boot device was not present in the
resource list:
1. If you booted from IDE CD-ROM Standalone Diagnostics, follow these steps:
a. Check the SCSI cables
b. Remove all hot-swap disk drives except the intended boot device if it’s a
hot-swap drive.
c. Disconnect all other internal SCSI devices.
d. Replace the SCSI cables
e. Replace the repeater card
f. Replace the SCSI backplane
g. Replace the intended boot device.
h. Replace the system board.
2. Go to the Task Selection Menu and select Task, Display Configuration and
Resource List. If the intended boot device is not listed, go to
″
MAP 0290: Missing
Resource Problem Resolution
″
in the RS/6000
Eserver
pSeries Diagnostic
Information for Multiple Bus Systems manual.
3. If an SRN, not an 8-digit error code, is reported, go to the RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems manual.
4. If the diagnostics are successful, and no other devices have been disconnected, it
may be necessary to perform an operating system-specific recovery process, or
reinstall the operating system.
5. If you replaced the indicated FRUs and the problem is not corrected, or the above
descriptions did not address your particular situation, go to “MAP 1540: Minimum
Configuration” on page 59.
If the problem has been corrected, go to
″
MAP 0410: Repair Checkout
″
in RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems.
If diagnostics do not boot successfully, and a SCSI boot failure is also occurring, go to
“MAP 1540: Minimum Configuration” on page 59.
If diagnostics do not boot successfully, and a SCSI boot failure is not occurring:
1. Check IDE cabling to boot device.
2. Check device configuration jumpers.
If no problem is found with the cabling or the jumpers, continue to “Step 4” on
page 108.
