Features Introduced Before A.11.20

The following subsections discuss important features that were added to Serviceguard in recent

releases and patches. All of these features have been carried forward into A.11.20.

Features First Introduced in Serviceguard A.11.19 Patches

Listed below are features originally introduced in patches to Serviceguard version A.11.19.

• Support for CFS, VxVM and CVM version 5.0.1 on HP-UX 11i v3 only.

• Improved support for IPv6, including support for IPv6–only hosts.

See the section “About Hostname Address Families: IPv4-Only, IPv6-Only, and Mixed Mode”

in chapter 4 of Managing Serviceguard, at the address given under “Documents for This

Version” (page 34).

• Improved support for online package maintenance.

See “Maintaining a Package: Maintenance Mode” in chapter 7 of Managing Serviceguard.

• Support for Dynamic Root Disk (DRD) on HP-UX 11i v3.

See “Upgrade Using DRD” (page 44).

• New Serviceguard Manager capabilities; see “Serviceguard Manager” (page 24).

• New -K option for cmgetconf.

This causes cmgetconf to skip probing of volume groups, allowing the command to complete

faster; the resulting cluster configuration file will not contain a list of cluster-aware volume

groups. See cmgetconf (1m) for more information.

• Support for Shared LVM (SLVM) in an HPVM environment only — that is, when the cluster

includes virtual machines (either as nodes or within packages) that are managed by HPVM.

For more information, see HP Integrity Virtual Machines Installation, Configuration, and

Administration at http://www.hp.com/go/hpux-hpvm-docs. For more information about using

HPVM in a Serviceguard cluster, see “Support for HP Integrity Virtual Machines (HPVM)”

(page 33).

• Improved support for nested mount points.

Serviceguard now ensures that a package will never attempt to mount a nested directory

concurrently with the parent, no matter what

concurrent_mount_and_umount_operations is set to. (In earlier releases, this could

happen if concurrent_mount_and_umount_operations was set to a value greater

than 1.)
