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 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:
• PHCO_37562
mkfs and mkboot Commands
The mkfs and mkboot commands check whether a specified disk device is being used by LVM;
if so, they display an error message. For these commands to correctly check whether a device is
part of a Version 2.0 volume group, you must install the following patches:
• PHCO_37328
• PHCO_37340
• PHCO_37394
These patches are delivered in the FEATURE11i bundle.
Serviceguard
To support Version 2.0 volume groups, Serviceguard 11.18 requires the following patch:
• PHSS_37602
VxVM 4.1 Commands
Several VxVM 4.1 commands check whether a specified disk device is being used by LVM before
overwriting it. For these commands to correctly check whether a device is part of a Version 2.0
volume group, you must install the following patch:
• PHCO_37836
Required Disk Space
Since LVM is installed with the HP-UX 11i v3 operating environment, it consumes no additional
disk space.
MirrorDisk/UX consumes no additional disk space aside from a license key.
