Does an SRC appear on the Display
Missing Disk Units display, or does the
Suspend Missing Disk Units display appear
on the console?
No Yes
~ Go to step 10 of this procedure.
9
Look at all the error logs by selecting the
Error log utility option under DST (see
"System Tools" in the Service Functions
User's Guide).
Is an SRC logged as a result of this IPL?
Yes No
The last device disconnected from
the system is failing.
Exchange the device and reconnect
the devices you disconnected from
the system.
Note: Before exchanging a disk
unit, you should attempt to save
customer data (see "Disk Service
Support" on page 5-4).
This ends the procedure.

Record the SRC on the Problem Summary
Form (see Appendix 0, "Problem Summary
Form" on page 0-1).
Is the SRC the same one that sent you to
this procedure?
No Yes
~ The last device disconnected from
the system is not failing.
a. Leave the device disconnected
and go to step 6 of this proce-
dure to continue isolation.
b. If all devices identified by FI
code FI011 06 have been dis-
connected, except disk unit 1 in
the system unit, reconnect all
devices and go to step 13 of
this procedure.

13, or are all the reference codes shown on
the console OOOO?
No Yes
~
The last device disconnected from
the system is failing.
Exchange the device and reconnect
the devices you disconnected from
the system.
Note: Before exchanging a disk
unit, you should attempt to save
customer data (see "Disk Service
Support" on page 5-4).
This ends the procedure.

Go to Chapter 2, "Unit Reference Codes"
on page 2-1. Use the new SRC to correct
the problem.
This ends the procedure.
13
Was disk unit 1 in the system unit one of
the parts identified by FI code FI011 06?
Yes No
~
The parts identified by FI code
FI01106 are not the failing parts.
Use the original SRC and exchange
the parts, starting with the highest
probable cause of failure (see the
failing item list for this reference
code). If the failing item list con-
tains FI codes, see "Failing Item
(FI) Code Table" on page 2-55. If
you need help in finding disk unit
part number locations in the
system, see "Disk Unit FRU
Locations" on page 3-7.
This ends the procedure.
14
The parts identified by FI code FI011 06,
other than disk unit 1, are not the failing
parts. Disk unit 1 in the system unit may
be failing. Use the original SRC and
exchange the parts, starting with the
highest probable cause of failure. See
"Disk Unit FRU Locations" on page 3-7 to
find the parts that need exchanging.
This ends the procedure.
