• A new utility allows you to monitor applications running inside Virtual Machine
(VM) guests. See “cmappmgr” (page 29).
• 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.
• A new cluster parameter, NETWORK_AUTO_FAILBACK, tells Serviceguard how
to handle the recovery of the primary LAN interface after it has failed over to the
standby interface because of a link level failure. See the description of this parameter
under “Cluster Configuration Parameters” in Chapter 4 of Managing Serviceguard.
• A new parameter, CONFIGURED_IO_TIMEOUT_EXTENSION, must be set for
extended-distance clusters using software mirroring across data centers over links
between iFCP switches. This parameter is supported only with iFCP switches that
allow you to get their R_A_TOV value, and must be set to the maximum R_A_TOV
value.
Serviceguard on HP-UX 11i v3
Serviceguard support for HP-UX 11i v3 was first introduced in Serviceguard version
A.11.17.01. The following is a list of the most important capabilities that are available
only on 11i v3.
• Serviceguard A.11.19 on HP-UX 11i v3 supports HP-UX agile addressing,
sometimes also called persistent LUN binding, for device special files (DSFs).
See “About Device Special Files (DSFs)” (page 43).
• Serviceguard A.11.19 on HP-UX 11i v3 supports HP-UX native multipathing and
load balancing.
See “Native Multipathing, Veritas DMP, and Related Features in HP-UX 11i v3”
(page 18).
