Step 3
Try to boot and run standalone diagnostics against the system, particularly against the intended boot
device.
If diagnostics do not boot successfully, and a SCSI boot failure (cannot boot from a SCSI-attached device)
is also occurring, go to "MAP 1548: Processor Subsystem Problem Isolation" on page 113.
If diagnostics do not boot successfully, and a SCSI boot failure (cannot boot from a SCSI-attached device)
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, go to "Step 4" on page 157.
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 output of the "Display Configuration and Resource List", which is run from
the Task Selelction Menu:
1. If you booted standalone diagnostics from IDE CD-ROM, follow these steps. After each action, do the
following:
Restart the system. Stop at the SMS menus and select Select Boot Options. If the device is present
in the boot list, and it was not showing up previously, go to MAP 0410: Repair Checkout in the
RS/6000 Eserver pSeries Diagnostic Information for Multiple Bus Systems.
If the device still does not show up, continue with the actions shown in the list.
a. Check the SCSI cables
b. Remove all hot-swap disk drives except the intended boot device if its a hot-swap drive. If the boot
device is present in the boot list when the system is booted to the SMS menus, add the hot-swap
disk drives back in, one at a time, until the failing device is isolated.
c. Disconnect all other internal SCSI devices. If the boot device is present in the boot list when the
system is booted to the SMS menus, reconnect the internal SCSI devices, one at a time, until the
failing device or cable is isolated.
d. Replace the SCSI cables
e. Replace the SCSI (DASD / Media) backplane
f. Replace the intended boot device.
g. Replace the CEC backplane.
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. Choose one of the following, then go to step 5.
v 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.
v If the diagnostics are successful, and devices have been removed, reinstall them one at a time.
After each device is reinstalled, reboot the system. Continue this procedure until the failing device is
isolated. Replace the failing device.
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 1548: Processor Subsystem Problem Isolation" on page
113.
