Reinstallation Recovery
Reinstallation is necessary if all copies of your root (boot) disk are
damaged, or if certain critical files are lost due to file system damage. On
HP-UX 11i Version 1.5, first use the recovery methods described in
“VxVM Boot Disk Recovery”. Follow the procedures below only if those
methods fail.
If these types of failures occur, attempt to preserve as much of the
original Volume Manager configuration as possible. Any volumes not
directly involved in the failure may be saved. You do not have to
reconfigure any volumes that are preserved.
General Reinstallation Information
This section describes procedures used to reinstall Volume Manager and
preserve as much of the original configuration as possible after a failure.
NOTE System reinstallation destroys the contents of any disks that are used for
reinstallation.
All Volume Manager related information is removed during
reinstallation. Data removed includes data in private areas on removed
disks that contain the disk identifier and copies of the Volume Manager
configuration, The removal of this information makes the disk unusable
as a Volume Manager disk.
The system root disk is always involved in reinstallation. Other disks
can also be involved. If the root disk was placed under Volume Manager
control, during Volume Manager installation, that disk and any volumes
or mirrors on it are lost during reinstallation. Any other disks that are
involved in the reinstallation, or that are removed and replaced, can lose
Volume Manager configuration data (including volumes and mirrors).
If a disk, including the root disk, is not under Volume Manager control
prior to the failure, no Volume Manager configuration data is lost at
reinstallation. For information on replacing disks, see Chapter 4, Disk
Tasks,.
Although it simplifies the recovery process after reinstallation, not
