Step 14. Restart the server. The system begins the power-on self-test (POST). If this does not recover the
primary bank, continue with the following steps.
Step 15. Remove the cover (see “Removing the cover” on page 34).
Step 16. Reset the CMOS by removing the system battery (see “Removing the system battery” on page 269).
Step 17. Leave the system battery out of the server for approximately 5 to 15 minutes.
Step 18. Reinstall the system battery (see “Replacing the system battery” on page 271).
Step 19. Reinstall the cover (see “Replacing the cover” on page 190).
Step 20. Reconnect the power cord and any cables that you removed.
Step 21. Restart the server. The system begins the power-on self-test (POST).
Step 22. If these recovery efforts fail, contact your service representative for support.
In-band automated boot recovery method
Use this information to recover the server firmware and restore the server operation to the primary bank.
Note:
Use this method if the BOARD LED on the light path diagnostics panel is lit and there is a log entry
or
Booting Backup Image
is displayed on the firmware splash screen; otherwise, use the in-band manual
recovery method.
Step 1.
Boot the server to an operating system that is supported by the firmware update package that
you downloaded.
Step 2.
Perform the firmware update by following the instructions that are in the firmware update package
readme file.
Step 3.
Restart the server.
Step 4.
At the firmware splash screen, press F3 when prompted to restore to the primary bank. The
server boots from the primary bank.
Out-of-band method
Use this information to recover the server firmware and restore the server operation to the primary bank.
See the IMM2 documentation (
Integrated Management Module II User's Guide
) at
http://www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5086346.
Automated boot recovery (ABR)
While the server is starting, if the integrated management module II detects problems with the server
firmware in the primary bank, the server automatically switches to the backup firmware bank and gives you
the opportunity to recover the firmware in the primary bank.
For instructions for recovering the UEFI firmware, see “Recovering the server firmware (UEFI update failure)”
on page 160. After you have recovered the firmware in the primary bank, complete the following steps:
Step 1.
Restart the server.
Step 2.
When the prompt
Press F3 to restore to primary
is displayed, press F3 to start the server from
the primary bank.
Nx-boot failure
Configuration changes, such as added devices or adapter firmware updates, and firmware or application
code problems can cause the server to fail POST (the power-on self-test).
