Use this procedure to perform an IPL to dedicated service tool
(DST) to determine if the same reference code occurs.
If a new reference code occurs, more analysis may be possible with
the new reference code. If the same reference code occurs, you are instructed
to exchange the failing items.
- If the system has logical partitions, perform this procedure from
the logical partition that reported the problem. To determine if
the system has logical partitions, go to Determining if the system has logical partitions ,
before continuing with this procedure.
- Was the IPL performed from disk (Type A or Type B)?
- No: Continue with the next step.
- Yes: Go to step 5.
- Perform the following:
- Ensure that the IPL media is the correct version and level that
are needed for the system model.
- Ensure that the media is not physically damaged.
- Choose from the following options to clean the IPL media:
- If it is cartridge type optical media (for example, DVD), do not attempt
to clean the media.
- If it is non-cartridge type media (for example, CD-ROM), wipe the disc
in a straight line from the inner hub to the outer rim. Use a soft, lint-free
cloth or lens tissue. Always handle the disc by the edges to avoid finger
prints.
- If it is tape, clean the recording head in the tape unit. Use the correct
Cleaning Cartridge Kit provided by your service provider.
- Perform a Type D IPL in Manual mode.
Does a system reference code (SRC) appear on the control panel?
- No: Go to step 8.
- Yes: Is the SRC the same one that sent you to this
procedure?
- Yes: You cannot continue isolating the problem.
Use the original SRC and exchange the failing items, starting with the highest
probable cause of failure. Refer to the reference code list. If the failing
item list contains FI codes, see System FRU locations to help determine
part numbers and location in the system. This ends the procedure.
- No: A different SRC occurred. Use the new SRC
to correct the problem. See Start of Call . This ends
the procedure.
- Perform an IPL to DST. See Performing an
IPL to dedicated service tools .
Does
an SRC appear on the control panel?
- No: Continue with the next step.
- Yes: Go to step 10.
- Does either the Disk Configuration Error Report, the Disk Configuration
Attention Report, or the Disk Configuration Warning Report display appear
on the console?
- No: Continue with the next step.
- Yes: Select option 5, press F11,
then press Enter to display the details. Then, choose
from the following options:
- Look at the product activity log. See Using the product activity log for
details.
Is an SRC logged as a result of this IPL?
- Yes: Continue with the next step.
- No: The problem cannot be isolated any more. Use
the original SRC and exchange the failing items. Start with the highest probable
cause of failure in the failing item list for this reference code. If the
failing item list contains FI codes, see System FRU locations to help determine
part numbers and location in the system. This ends the procedure.
- Does either the Disk Configuration Error Report, the
Disk Configuration Attention Report, or the Disk Configuration Warning Report
display appear on the console?
- Yes: Continue with the next step.
- No: Look at the product activity log. See Using the product activity log for details.
Is an SRC logged as a result
of this IPL?
- Yes: Continue with the next step.
- No: The problem is corrected. This
ends the procedure.
- Select option 5, press F11,
then press Enter to display the details. Then,
choose from the following options:
- Record the SRC.
Are the SRC and unit
reference code (URC) the same ones that sent you to this procedure?
- Yes: Continue with the next step.
- No: Use the new SRC or reference code to correct
the problem. This ends the procedure.
- Perform the following steps:
- Power off the system or expansion tower. See Powering
on and powering off the system .
- Exchange the FRUs in the failing item list for the SRC you have
now. Start with the highest probable cause of failure in the failing
item column in the reference code list. Perform the remaining steps of this
procedure after you exchange each FRU until you determine the failing FRU.
Note: If
you exchange a disk unit, do not attempt to save customer data until instructed
to do so in this procedure.
- Power on the system or the expansion unit. See Powering on and
powering off the system .
Does an SRC appear on the control panel?
- No: Continue with the next step.
- Yes: Go to step 16.
- Does either the Disk Configuration Error Report, the Disk Configuration
Attention Report, or the Disk Configuration Warning Report display appear
on the console?
- Yes: Continue with the next step.
- No: Look at the product activity log. See Using the product activity log for details.
Is an SRC logged as a result
of this IPL?
- Select option 5, press F11,
then press Enter to display the details. Then,
choose from the following options:
- Record the SRC on the Problem summary form. See Using the product activity log for details.
Is the
SRC the same one that sent you to this procedure?
- Yes: The last FRU you exchanged is not the failing
FRU. Go to step 12 to continue FRU isolation.
- No: Is the SRC B100 4504 or B100 4505 and have
you exchanged disk unit 1 in the system unit, or are all the reference codes
on the console 0000?
