Veritas Volume Manager 5.0.1 Migration Guide, HP-UX 11i v3, First Edition, November 2009

■ If during a conversion only some of a set of volume groups converted

successfully, then you may want to restore the LVM configuration for the

entire set.

It is possible to restore the original LVM configuration in one of two ways, but

both have limitations and restrictions. The method you use depends on if any

changes have been made to the VxVM configuration since the conversion occurred.

Any of the following actions changes the VxVM configuration:

■ adding or removing disks

■ adding or removing volume groups

■ changing the names of VxVM objects

Restoration methods include:

■ rollback using vxvmconvert

Use rollback only if the VxVM configuration has not changed since the

conversion. This method restores the LVM configuration without the need for

user data restoration. Additional information is available on the rollback

method.

See “Rollback to LVM using vxvmconvert” on page 35.

■ restore user data using vgrestore and frecover

This method is a full LVM restoration which is used to restore your user data

from backup when the VxVM configuration has changed since the conversion

was made. First of all, this method restores the original LVM configuration

information (vgrestore), and then restores the original user data from the

backup that was made before the conversion was done (frecover). Additional

information is available on full LVM restoration.

See “Full LVM restoration” on page 36.
