Chapter 2, Recovery from Boot Disk Failure

Recovery by Reinstallation

Reinstalling the System and Recovering VxVM

To reinstall the system and recover the VERITAS Volume Manager conﬁguration, use the

following procedure. These steps are described in detail in the sections that follow:

1. “Prepare the System for Reinstallation” on page 29.

Replace any failed disks or other hardware, and detach any disks not involved in the

reinstallation.

2. “Reinstall the Operating System” on page 30.

Reinstall the base system and any other unrelated Volume Manager packages.

3. “Reinstall VxVM” on page 30.

Add the Volume Manager package, but do not execute the vxinstall command.

4. “Recover the VERITAS Volume Manager Conﬁguration” on page 30.

5. “Clean up the System Conﬁguration” on page 32.

Restore any information in volumes affected by the failure or reinstallation, and

recreate system volumes (rootvol, swapvol, usr, and other system volumes).

6. “Start up Hot-Relocation” on page 36.

Prepare the System for Reinstallation

To preventthe loss ofdata on disksnot involved inthe reinstallation, involve onlythe root

disk in the reinstallation procedure.

Note Several of the automatic options for installation access disks other than the root disk

without requiring conﬁrmation from the administrator. Disconnect all other disks

containing volumes from the system prior to reinstalling the operating system.

Disconnecting the other disks ensures that they are unaffected by the reinstallation. For

example, if the operating system was originally installed with a home ﬁle system on the

second disk, it can still be recoverable. Removing the second disk ensures that the home

ﬁle system remains intact.
