HP Serviceguard Version A.11.20 Release Notes, April 2011

• Serviceguard supports LVM 2.x volume groups, both for data and the cluster lock. See “About
LVM 2.x” (page 30).
• Serviceguard now supports cell OL* (online addition and deletion of cells) on HP Integrity
servers that support them).
For more information about using Serviceguard with partitioned systems, see the white paper
HP Serviceguard Cluster Configuration for HP-UX 11i or Linux Partitioned Systems at http://
www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard.
• Serviceguard supports vgchange -T, which allows multi-threaded activation of volume
groups. See “About vgchange -T” (page 30).
• You can use the FSWeb utility to configure LVM volumes in a Serviceguard cluster (and SLVM
volumes if the add-on product Serviceguard Extension for Real Application Cluster (SGeRAC)
is installed).
For more information about FSWeb, see the fsweb (1m) manpage.
• Serviceguard supports the following recently added HP-UX 11i v3 capabilities:
◦ Dynamic Root Disk (DRD); see “Upgrade Using DRD” (page 44).
See also “What’s Not in this Release” (page 15).

About the New Features
The subsections that follow discuss the major new capabilities introduced in the A.11.20 release,
as well as those introduced in patches to A.11.20. Information on using these capabilities is in
the latest version of Managing Serviceguard, which you can find at the address given under
“Documents for This Version” (page 34).
Modular CFS Packages for Reducing Package Usage
With modular CFS packages, Serviceguard provides the flexibility to combine all the CVM disk
groups and CFS mount points required by an application into a single package using the modular
style of packaging. As a result, the number of packages used for configuring disk groups and
mount points in that cluster reduces significantly compared to the packages used for configuring
the same in the legacy style of packaging. This helps in easy management of the packages in that
cluster and leaves more packages for other applications. You can also merge all the checkpoints
and snapshot packages into individual modular checkpoint and snapshot packages respectively.
