Recovering a system by booting from a VxVM root

disk mirror

If a failed primary boot disk is under VxVM control and is mirrored, it must be

replaced.

To recover a system by booting from a VxVM root disk mirror

Replace the failed disk. Depending on the system hardware, this may require

you to shut down and power off the system.

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 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.
