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. Volume group availability
was improved: resizing a LUN and modifying volume group characteristics
no longer required the volume group to be recreated, and replacing
a disk could be done online.
The September 2008 release of LVM and MirrorDisk/UX
continues to extend the limits of mass storage, supporting a larger
number of volume groups, logical volumes, and physical volumes. This
release also allows a volume group to take advantage of LUN expansion online, detects and corrects problems with
the boot disk's hardware path, and displays additional information.
