Perform a type-D IPL in manual mode to DST. Look for other SRCs
and use them to resolve the problem. If there are no SRCs, or if the SRCs
do not resolve the problem, perform the actions for the 2847 3100 SRC. This
ends the procedure.
Is the device in a valid location (see Locating FRUs)?
Yes: Continue with the next step.
No: Correct the device location problem and retry the IPL. If
the problem persists, continue with the next step.
Perform a type-D IPL in manual mode to DST. Is the type-D IPL successful?
No: Continue with the next step.
Yes: Look for other SRCs and use them to resolve the problem. If
there are no SRCs, or the SRCs do not resolve the problem, replace the following
items, one at a time, until the problem is resolved (see Physical Locations):
Load source disk drive
Cables (if present)
Disk drive backplane
I/O adapter controlling the load source device
Note:
The I/O adapter may
be embedded on the system unit backplane
Backplane that the I/O adapter is plugged into
If the problem persists after replacing each of these parts, contact your
next level of support. This ends the procedure.
The type-D IPL in manual mode to DST was not
successful. Is the I/O adapter embedded on the system unit backplane?
No: Continue with the next step.
Yes: Replace the system unit backplane and retry the IPL. If the
IPL still fails, contact your next level of support. This ends the procedure.
Are the load source and alternate load source controlled by the
same I/O adapter?
Replace the I/O adapter and perform a type-A or type-B IPL. Does
the IPL complete successfully?
Yes:This ends the procedure.
No: Continue with the next step.
Perform a type-D IPL in manual mode to DST. Is the type-D IPL successful?
No: Continue with the next step.
Yes: Look for other SRCs and use them to resolve the problem. If

Cables (if present)
Disk drive backplane
I/O adapter controlling the load source device
Note:
The I/O adapter may

Backplane that the I/O adapter and I/O processor are plugged into
If the problem persists after replacing each of these parts, contact your
next level of support. This ends the procedure.
Replace the backplane that the I/O adapter
is plugged into and retry the IPL. If the IPL still fails, contact your next
level of support. This ends the procedure.
