Preparing the System for Reinstallation
To prevent the loss of data on disks not involved in the reinstallation,
involve only the 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.
Reinstalling the Operating System
Once any failed or failing disks have been replaced and disks not
involved with the reinstallation have been detached, reinstall the
operating system as described in your operating system documentation.
Install the operating system prior to installing Volume Manager.
Ensure that no disks other than the root disk are accessed in any way
while the operating system installation is in progress, If anything is
written on a disk other than the root disk, the Volume Manager
configuration on that disk can be destroyed.
NOTE During reinstallation, you can change the host ID (or name). It is
recommended that you keep the existing host ID (name), as the sections
that follow assume that you have not changed your host ID (name).
