Symptom Action
The SMS configuration list or Boot sequence
selection menu shows more SCSI devices
attached to a controller/adapter than are actually
attached. A device may be set to use the same SCSI bus
ID as the control adapter. Note the ID being
used by the controller/adapter (this can be
checked and/or changed via an SMS utility), and
verify that no device attached to the controller is
set to use that ID.
If settings do not appear to be in conflict:
1. Replace the SCSI cable.
2. Replace the device.
3. Replace the SCSI adapter (or I/O board if
connected to one of the two integrated SCSI
controllers on the I/O board). (See notes on
2-1 if the I/O board is replaced.)
Note: In a "Twin-tailed" configuration where
there is more than one initiator device
(normally another system) attached to
the SCSI bus, it may be necessary to
change the ID of the SCSI controller or
adapter with the System Management
Services.
The System Management Services menu is
displayed. The device or media you are attempting to boot
from may be faulty.
1. Check the SMS error log for any errors. To
check the error log:
a. Choose error log
b. If an error is logged, check the time
stamp.
c. If the error was logged during the
current boot attempt,record it.
d. Look up the error in “Checkpoints” on
page 3-34 and do the listed action.
e. If no recent error is logged in the error
log, continue to the next step below.
2. Try to boot from an alternate boot device
connected to the same controller as the
original boot device. If the boot succeeds,
replace the original boot device (for
removable media devices try the media first.
3. Go to “MAP 1540: Minimum Configuration”
on page 2-31.
You have a problem that does not prevent the
system from booting. Go to the Fast Path MAP in the
IBM RS/6000
Diagnostic Information for Multiple Bus Systems.
You have an SRN. Go to the Fast Path MAP in the IBM RS/6000
