Logical Volume Manager and MirrorDisk/UX Release Notes About this document This document provides information about the Logical Volume Manager (LVM) and MirrorDisk/UX products in the March 2012 release of HP-UX 11i v3. LVM and MirrorDisk/UX overview Logical Volume Manager (bundle BaseLVM) is the HP-UX default Volume Manager. It provides 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.
Fixed issues in this version The following table lists the known LVM and MirrorDisk/UX defects fixed in the March 2012 release of HP-UX 11i v3.

Table 1 LVM Fixes in HP-UX 11i v3 March 2012 Release (continued) Defect ID Description Resolution details: vgversion has been enhanced so that the cluster lock can be removed by running vgchgid first and then subsequently running vgversion to upgrade the volume group. QXCR1001145030 In a 3 node cluster, the deactivation of a shared volume group in the server fails if any server crash occurred earlier followed by a deactivation of a volume group on the other client.

http://www2.itrc.hp.com/service/patch/mainPage.do Mass Storage Critical Resource Analysis The Mass Storage Critical Resource Analysis (MS CRA) tool checks for a maximum of two mirror copies of a logical volume. However, Version 2.0 and higher volume groups allow up to five mirror copies. To enable MS CRA to check for a maximum of five mirror copies of a volume, you must install the following patch, or a superseding patch: • PHCO_37562 MS CRA checks for a maximum of 511 physical volumes in a volume group.
HP Insight Remote Support Software HP strongly recommends that you install HP Insight Remote Support software to complete the installation or upgrade of your product and to enable enhanced delivery of your HP Warranty, HP Care Pack Service or HP contractual support agreement.
When using LVM configuration commands on legacy device special files, LVM does not select an alternate path if the path corresponding to the specified device special file is unavailable, unless the unavailable path and the alternate path are configured as part of an active volume group. When using LVM configuration commands on persistent device special files, LVM succeeds if at least one of the paths to the device is available.
As of this writing, larger logical volumes and striped mirrors are only available on HP-UX 11i v3 and HP-UX 11i v2 (with patches). For up-to-the-moment information, contact your Hewlett-Packard support representative or consult the Hewlett-Packard IT Resource Center site: http://itrc.hp.com (Americas and Asia Pacific) or http://europe.itrc.hp.com (Europe) for LVM patches.
