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 1540: Minimum Configuration” on
page 101.
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 152.
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 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 PCI riser card
f. Replace the SCSI backplane
g. Replace the intended boot device.
h. 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
