Comparison of LVM and VxVM tasks

This section contains a list of tasks which you can perform using LVM, and near

equivalent tasks which you can perform using Veritas Volume Manager. You can

perform the LVM tasks by using SMH or the command line interface. Similarly,

you can choose to perform VxVM tasks by using the Veritas Enterprise

Administrator (VEA) or the command line interface. This document focuses on

the command line interface.

Note: The following features in VxVM require an additional license: Mirroring,

Mirroring and Striping, Dynamic Multipathing of Active/Active Devices,

Hot-relocation, Online Migration, and RAID-5.

All the VxVM tasks listed in the task comparison chart can be performed by the

Veritas Enterprise Administrator.

See the Veritas Enterprise Administrator User’s Guide.

Additional information is available on LVM and VxVM commands.

See HP-UX Managing Systems and Workgroups.

See theLVM manual pages in HP-UX Reference Volumes 2, 3, and 5.

Note: Mirroring of a VxVM root disk is supported in this release.

Mirroring in LVM is supported only if you have MirrorDisk/UX already installed

as an add-on product. In addition, mirroring in VxVM requires an additional

license.
