Recovering a system by booting from recovery media

If there is a failure to boot from the VxVM boot disk on HP-UX 11i version 2, and no bootable root mirror is available, it may be necessary to boot from an alternate boot source, or from recovery media such as the following:

• HP-UX 11i version 2 installation disc.
• Bootable recovery tape.
• Secondary boot disk in the configuration.
• HP-UX Ignite-UX server that is accessible over a LAN.

The following problems that can only be repaired if the system is booted from recovery media:

• A corrupt or non-bootable HP-UX kernel.
• Missing files that are required for booting, such as:
  • /stand/ioconfig file.
  • Device files in /dev/vx.
• Corrupted LIF area on the boot disk.

Detailed information on how to recover from these and many other failures is documented in the Ignite-UX Administration Guide, which is available on the HP documentation web site.

If these methods fail, use the recovery by reinstallation procedure.
