Logical
Volume Manager (bundle BaseLVM™) is the
HP-UX default Volume Manager. It provides the user with flexibility
in configuring and managing mass storage resources. In HP-UX 11i v3,
the LVM kernel and commands are bundled with the core HP-UX product.
Overview of Changes |
|
The initial HP-UX 11i v3 release of LVM and MirrorDisk/UX
was integrated with the new mass storage stack, delivering significant
performance, scalability, availability, and usability enhancements.
LVM was enhanced to support larger logical volumes, temporary quiescing
of volume groups, and striping with mirroring. Operations that previously
required deactivation or re-creation of a volume group—such
as replacing a disk, resizing a LUN, and modifying volume group characteristics—can
now be performed online.
This September 2007 release of LVM and MirrorDisk/UX increases
performance by performing some operations in parallel, and increases
availability by proactively polling alternate paths to multi-pathed
disks.
