Introducing Veritas Volume Manager

Veritas Volume Manager is an alternative Volume Management product for HP-UX

that includes mirroring features. It offers many capabilities that are not available

with the LVM and MirrorDisk/UX products today, including the following

capabilities:

■ Veritas Volume Manager can coexist with LVM. Users can decide which volumes

they want managed by each volume manager. For users who want to migrate

LVM volume groups to VxVM disk groups, a conversion utility is included.

The vxvmconvert utility is used to convert LVM to VxVM.

See “About LVM to VxVM conversion” on page 19.

■ Veritas Volume Manager is available for installation with all HP-UX 11i Version

3 operating environments.
