HP-UX 11i Version 1.5 (B.11.20) includes IPF functionality for basic Logical
Volume Manager (LVM) features including non-boot disk support and
full mirroring capability on non-boot disks in a stand-alone configuration. LVM
boot disks are not supported in this release.
If you are familiar with LVM on previous releases of HP-UX
you have access to the same features on IPF-based platforms
as you had on PA-RISC platforms on earlier releases. In many cases,
the inclusion of LVM will aid your migration from PA to IPF. Instead
of being forced to start with clean disks or to migrate all of your
data to the VERITAS Volume Manager (VxVM), before moving to an Itanium-based
platform, you will be able to use your pre-built data along with
the LVM commands that are already familiar.
Note that not all LVM functionality is provided on IPF systems
for the HP-UX 11i Version 1.5 (B.11.20) release. High availability features such as Shared
LVM (SLVM - for cluster configurations) and Business Copy/BCV/ snapshot
features for high-end arrays are not supported. Likewise, support
for LVM-formatted boot disks is not supported (including root, swap
and dump to LVM disks) in this release.
Disk striping capability is provided with this version of
LVM on Itanium-based systems and, when used appropriately, may
significantly improve disk-access times. See Managing
Systems and Workgroups for more information.
LVM Compatibility |
 |
LVM data developed on a PA-RISC system may be imported to
be used on an IPF system (and vice-versa). Both PA-RISC and IPF platforms, however,
carry the same constraint that LVM-formatted devices are not compatible
with VxVM.
