36 Recovering from boot disk failure
Recovering a system by booting from recovery media
2 Boot the system from a mirror of the root disk, and use the vxrootmir
command to initialize and mirror the volumes on the new root disk:
# /etc/vx/bin/vxrootmir -v -b new_root_disk_access_name
The -b option sets the newly mirrored disk as the alternate boot disk in the
NVRAM. The -v option gives progress indications as each volume is being
mirrored.
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 3, 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 3 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.
See “Recovery by reinstallation” on page 39.
