Restoring firmware image from backup
Before the server adapter firmware image on the server is updated, the current image is saved in a file
called <MAC_ADDRESS>.bc<Boot Code version>.p<PXE version>.bin. The backup file is
saved in the /var/opt/hp/nicfw_backup directory of the target server.
Use the hpnicfwupg command with the –p option to restore the original firmware image after an
upgrade or after an upgrade failure. This option can only be used interactively. The firmware backup
directory is examined for saved images and a message is displayed showing the current firmware
versions and the versions from the saved image. You will be prompted before the restore is attempted. If
more than one saved image is found for a particular server adapter, you will be prompted for each
image.
The following is a sample screen shot of a typical restore.
