Reinstallation Recovery

Chapter 8338

having the root disk under Volume Manager control increases the

possibility of a reinstallation being necessary. By having the root disk

under Volume Manager control and creating mirrors of the root disk

contents, you can eliminate many of the problems that require system

reinstallation.

When reinstallation is necessary, the only volumes saved are those that

reside on, or have copies on, disks that are not directly involved with the

failure and reinstallation. Any volumes on the root disk and other disks

involved with the failure and/or reinstallation are lost during

reinstallation. If backup copies of these volumes are available, the

volumes can be restored after reinstallation. On some systems, the

exceptions are the root, stand, and usr ﬁle systems, which cannot be

restored from backup.

Reinstallation and Reconﬁguration Procedures

To reinstall the system and recover the Volume Manager conﬁguration,

use the following procedure. These steps are described in detail in the

sections that follow:

Step 1. Prepare the system for installation.

Replace any failed disks or other hardware, and detach any disks not

involved in the reinstallation.

Step 2. Install the operating system.

Reinstall the base system and any other unrelated Volume Manager

packages.

Step 3. Install Volume Manager.

Add the Volume Manager package, but

do not

execute the vxinstall

command.

Step 4. Recover the Volume Manager conﬁguration.

Step 5. Clean up the Volume Manager conﬁguration.

Restore any information in volumes affected by the failure or

reinstallation, and recreate system volumes (rootvol, swapvol, usr,

and other system volumes.).
