HP Serviceguard Version A.11.19 Release Notes, March 2009

New Serviceguard Features Common to HP-UX 11i v2 and 11i v3
The following features are new for A.11.19:
• You can configure new types of dependencies between packages. See “New Kinds
of Package Dependency” (page 23).
• You can configure package weights and node capacities, allowing you to control
broadly which packages can run simultaneously on a given node. See “About
Package Weights” (page 23).
• Other minor new package features are listed under “Other Package Changes First
Introduced in Serviceguard A.11.18 Patches” (page 32).
• Serviceguard now supports the IPv6 hostname address family for all cluster
components, with some restrictions. See “New Support for IPv6” (page 24).
• Serviceguard can now monitor subnets at the IP level, as well as the link level. See
“About the IP Monitor” (page 24).
• You can now make configuration changes while the cluster is running, particularly
in regard to the cluster lock, that were not allowed online in previous releases, or
were restricted; see “New Online Cluster Configuration Capabilities” (page 25).
• In the case of modular packages, you can now make most package configuration
changes while the package is running, and you can also make more changes to
legacy packages online. See “New Online Package Configuration Capabilities”
(page 25). (For information about modular and legacy packages, see Chapter 6 of
the latest version of Managing Serviceguard.)
• You can now preview the effects both of individual commands and of large-scale
cluster changes; see “New Preview Capabilities” (page 25).
• You can now partially start a modular package so as to perform maintenance on
the modules that are not started; see “About Partial-Startup Maintenance Mode”
(page 25).
• A new utility allows you to monitor applications running inside Virtual Machine
(VM) guests. See “About cmappmgr” (page 26).
• You can now configure a maximum of 300 packages in a cluster. The previous
limit was 150.
• A quorum server can now support up to 150 clusters comprising up to 300 nodes.
The previous limits were 50 clusters and 100 nodes. The new limits are supported
in Quorum Server versions A.02.04 and later.
• There are new Serviceguard demons:
— Service Assistant Daemon: cmserviced (replaces cmsrvassistd)
— Cluster WBEM Agent Daemon: cmwbemd
— Proxy Daemon: cmproxyd
See the section “Serviceguard Daemons” in Chapter 3 of the latest edition Managing
Serviceguard for more information about these daemons.
