Note: Use this method if the standard I/O book board LED is lit and there is a logentry or Booting Backup Image is displayed on the firmware splash screen;otherwise, use the in-band manual recovery method.1. Boot the server to an operating system that is supported by the firmwareupdate package that you downloaded.2. Perform the firmware update by following the instructions that are in thefirmware update package readme file.3. Restart the server.4. At the firmware splash screen, press F3 when prompted to restore to theprimary bank. The server boots from the primary bank.Out-of-band method: See the IMM2 documentation (Integrated Management ModuleII User's Guide) at http://www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5086346.For more information about UEFI-compliant firmware, go to http://www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5083207.Automated boot recovery (ABR)This topic provides instructions on how to recover the server primary bankfirmware.About this taskIf the server is booting up and the IMM detects problems with the server firmwarein the primary bank, it will automatically switch to the backup firmware bank andgive you the opportunity to recover the primary bank. To recover to the serverfirmware primary bank, complete the following steps.Procedure1. Restart the server.2. When the prompt press F3 to restore to primary is displayed, press F3 torecover the primary bank. Pressing F3 will restart the server.Nx boot failureThis topic provides information about how to set the Nx boot failure feature to setthe number of attempts to automatically restart the server after a POST failure.About this taskConfiguration changes, such as added devices or adapter firmware updates, andfirmware or application code problems can cause the server to fail POST (power-onself-test). If this occurs, the server responds in either of the following ways:v The server restarts automatically and attempts POST again.v The server hangs, and you must manually restart the server for the server toattempt POST again.After a specified number of consecutive attempts (automatic or manual), the Nxboot failure feature causes the server to revert to the default UEFI configurationand start the Setup utility so that you can make the necessary corrections to theChapter 4.
