Automatic boot may fail for HP-UX after a restore
Sometimes after a Bare Metal Restore (BMR) restore and during the first boot of the client computer, the operating system automatic boot may fail. The HP BIOS then fails to identify the boot drive.
To resolve this issue, use the shell and select a hard drive that you can boot from (for example, fs0:) by looking at the device mapping table.
Change the directory (cd) to \EFI\HPUX\ and run to boot the operating system manually.
Note:
Refer to the HP EFI manuals for more details on how to handle the EFI shell.
Once the client computer comes up, log on to the computer as root and run the following command to enable auto-booting.
setboot -p <hardware_path_of_boot_harddrive>
