The SRNs
SRN FRU List Problem
10112 None Description: Format Degraded. A Format operation has been
ended before it has completed.
Action: Use the Format service aid to format the disk drive
module.
1XXXX Disk-drive module (100%)
(“Disk Drive Modules” on page 3-17). Description: Disk drive module error.
Action: Exchange the FRU for a new FRU.
Note: In this SRN, an X represents a digit 0 through F.
20PAA Disk-drive module (45%)
(“Disk Drive Modules” on page 3-17).
SSA adapter card (45%)
(using-system Inst and Service Guide).
|
External SSA cables, Fibre-Optic
|
Extenders or fiber optic cables (6%).
Backplane assembly (2%)
(“Front Backplane Assembly” on
page 3-48 or “Back Backplane Assembly”
on page 3-52).
|
Signal card or bypass card (2%)
(“Signal Cards and Bypass Cards” on
page 3-43).
Description: An open SSA loop has been detected.
Action: Run the Link Verification service aid to isolate the failure
|
(see the chapter about SSA service aids in the SSA Adapters:
|
User’s Guide and Maintenance Information manual).
If the SSA service aids are not available:
When the failing device is in a 7133, go to step 12 on
page 2-2010-5 in “MAP 2010: 7133 – START.”
When the failing device is not in a 7133, go to the service
information for that device.
21PAA
to
29PAA
Disk-drive module (45%)
(“Disk Drive Modules” on page 3-17).
SSA adapter card (45%)
(using-system Inst and Service Guide).
|
External SSA cables, Fibre-Optic
|
Extenders or fiber optic cables (6%).
Backplane assembly (2%)
(“Front Backplane Assembly” on
page 3-48 or “Back Backplane Assembly”
on page 3-52).
|
Signal card or bypass card (2%)
(“Signal Cards and Bypass Cards” on
page 3-43).
Description: An SSA ‘Threshold exceeded’ link error has been
detected.
|
Action: Go to the Intermittent Link Error MAP in the SSA
|
Adapters: User’s Guide and Maintenance Information manual.
2A002 Disk-drive module (50%)
(“Disk Drive Modules” on page 3-17).
SSA adapter card (50%)
(using-system Inst and Service Guide). Description: Async code 02 has been received. Probably, a
software error has occurred.
Action: Go to “Software and Microcode Errors” on page 2-8
before exchanging any FRUs.
2A003 Disk-drive module (50%)
(“Disk Drive Modules” on page 3-17).
SSA adapter card (50%)
(using-system Inst and Service Guide). Description: Async code 03 has been received. Probably, a
software error has occurred.
Action: Go to “Software and Microcode Errors” on page 2-8
before exchanging any FRUs.
2A004 Disk-drive module (50%)
(“Disk Drive Modules” on page 3-17).
SSA adapter card (50%)
(using-system Inst and Service Guide). Description: Async code 04 has been received. Probably, a
software error has occurred.
Action: Go to “Software and Microcode Errors” on page 2-8
before exchanging any FRUs.
2A005 None Description: Async code 05 has been received. This code
indicates that a disk drive module has detected the loss of
redundant power or cooling.
|
Action: Use the Link Verification service aid (see the chapter
|
about SSA service aids in the SSA Adapters: User’s Guide and
|
Maintenance Information manual) to determine whether any
devices are missing from the SSA loop. If a device is missing, go
to “MAP 2010: 7133 – START” on page 2-2010-1 to isolate the
problem.
If no device is missing, the problem might have been caused by a
temporary, or partial, loss of power to the 7133.
