Updating System Firmware from a NIM Server
Refer to “Running Standalone Diagnostics from a Network Installation Management (NIM) Server” on
page 360.
Recovery Mode
If the service processor detects that its programming has been corrupted when it is powering on to
standby mode, it will enter recovery mode. In recovery mode, it prompts for the firmware update diskettes
by putting eight-digit codes on the operator panel display, as shown in the following table. After the update
process is complete, the service processor resets itself and performs a complete reboot.
Code Action
A1FD 0000 System firmware has been corrupted and must be reflashed.
A1FD 0001 Insert update diskette 1.
A1FD 0002 Insert update diskette 2.
A1FD 0003 Insert update diskette 3.
A1FD 000n Insert update diskette n.
Notes:
1. If the wrong diskette is inserted at any time, or if the diskette is left in the drive after it has been read,
B1FD 001F is displayed, indicating that the wrong diskette is in the drive.
2. If
B1FD 001A
is displayed at any time during the process, the service processor must be reset by
activating the pinhole reset switch on the primary drawer operator panel.
Updating System Firmware from the AIX Command Line
For information about updating system firmware, refer to the Web site for detailed instructions on the latest
image provided.
Note: The update process can take up to 60 minutes, and the system reboots itself during the update
process.
Configuring and Deconfiguring Processors or Memory
All failures that crash the system with a machine check or check stop, even if intermittent, are reported as
a diagnostic callout for service repair. To prevent the recurrence of intermittent problems and improve the
availability of the system until a scheduled maintenance window, processors and memory DIMMs with a
failure history are marked
″
bad
″
to prevent their being configured on subsequent boots. This function is
called repeat gard .
A processor or memory DIMM is marked
″
bad
″
under the following circumstances:
v
A processor or memory DIMM fails built-in self-test (BIST) or power-on self-test (POST) testing during
boot (as determined by the service processor).
v A processor or memory DIMM causes a machine check or check stop during runtime, and the failure
can be isolated specifically to that processor or memory DIMM (as determined by the processor runtime
diagnostics in the service processor).
v
A processor or memory DIMM reaches a threshold of recovered failures that results in a predictive
callout (as determined by the processor run-time diagnostics in the service processor).
During boot time, the service processor does not configure processors or memory DIMMs that are marked
“bad.”
