SRN FRU List Problem
2A006 Disk-drive module (90%)
(“Disk Drive Modules” on page 3-17).
Backplane assembly (10%)
(“Front Backplane Assembly” on
page 3-48 or “Back Backplane Assembly”
on page 3-52). Description: Async code 06 has been received. This code
indicates that a disk drive module has detected the loss of
redundant power or cooling.
Action: Go to “MAP 2021: 7133 – Redundant Power” on
page 2-2021-1 to further isolate the problem.
2A106 Fan-and-power-supply assembly (90%)
(“Fan-and-Power-Supply Assemblies” on
page 3-32).
Power-distribution tray assembly (6%)
(“Power-Distribution Tray Assemblies” on
page 3-38).
Back-power card (2%)
(“Back-Power Cards” on page 3-41).
Backplane assembly (2%)
(“Front Backplane Assembly” on
page 3-48 or “Back Backplane Assembly”
on page 3-52). Description: Async code 06 has been received. This code
indicates that multiple disk drive modules have detected the loss
of redundant power or cooling.
Action: Go to “MAP 2010: 7133 – START” on page 2-2010-1 to
further isolate the problem.
2A206 Disk drive module (100%)
(“Disk Drive Modules” on page 3-17). Description: A disk drive module has detected that one of its SSA
links has failed the POSTs.
|
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 where the SSA
link is broken. Run diagnostics in System Verification mode to
the two disk drive modules that are nearest to, and on each side
of, the place where the link is broken. The diagnostics show
which disk drive module detected the problem.
2FFFF None Description: An async code that is not valid has been received.
Action: Go to “Software and Microcode Errors” on page 2-8.
300C0 Disk drive module (90%)
(“Disk Drive Modules” on page 3-17).
Backplane assembly (10%)
(“Front Backplane Assy” on page 3-48 or
“Back Backplane Assy” on page 3-52). Description: A disk drive module has detected the loss of
redundant power or cooling.
Action: Go to “MAP 2021: 7133 – Redundant Power” on
page 2-2021-1 to further isolate the problem.
301C0 Fan-and-power-supply assembly (90%)
(“Fan-and-Power-Supply Assemblies” on
page 3-32).
Power-distribution tray assembly (6%)
(“Power-Distribution Tray Assemblies” on
page 3-38).
Back-power card (2%)
(“Back-Power Cards” on page 3-41).
Backplane assembly (2%)
(“Front Backplane Assy” on page 3-48 or
“Back Backplane Assy” on page 3-52). Description: Multiple disk drive modules have detected the loss of
redundant power or cooling.
Action: Go to “MAP 2010: 7133 – START” on page 2-2010-1 to
further isolate the problem.
303FF Disk drive module (100%)
(“Disk Drive Modules” on page 3-17). Description: An SCSI status that is not valid has been received.
Action: Go to “Software and Microcode Errors” on page 2-8
before exchanging any FRUs.
|
31000
|
Disk drive module (100%) (“Disk Drive
|
Modules” on page 3-17).
|
Description: The disk drive has been reset by the adapter. The
|
disk drive might be going to fail.
|
Action: If the disk drive can still be accessed, the user should
|
create a backup of all the data from this disk drive, then remove
|
the disk drive from the system configuration. Exchange the FRU
|
for a new FRU.
