HP Serviceguard Version A.11.19 Release Notes, March 2009

Serviceguard Features Available Only on HP-UX 11i v3
Serviceguard support for the following HP-UX 11i v3 capabilities was first introduced
in Serviceguard version A.11.17.01:
• 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 39).
• 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).
• There are new networking capabilities:
— The HP-UX olrad -C command now identifies network interface cards (NICs)
that are part of the Serviceguard cluster configuration.
You can remove a NIC from the cluster configuration, and then from the system,
without bringing down the cluster. See “About olrad” (page 38).
— Serviceguard now also supports the LAN Monitor mode of APA.
• Serviceguard supports Process IDs (PIDs) of any size, up to the maximum value
supported by HP-UX and the node’s underlying hardware architecture.
Previous versions of HP-UX imposed a limit of 30,000; this limit has been removed
as of HP-UX 11i v3. For more information, see the white paper Number of Processes
and Process ID Values on HP-UX on docs.hp.com.
Serviceguard support for the following HP-UX 11i v3 capabilities was first introduced
in Serviceguard A.11.18 (or a patch to that release):
• Serviceguard A.11.19 supports the increased number of LVM volume groups
supported as of the HP-UX 11i v3 0809 Fusion release; the maximum number of
volume groups you can configure in a Serviceguard cluster is the maximum
supported by HP-UX. See the HP-UX documentation for details.
• Serviceguard A.11.19 on HP-UX 11i v3 supports LVM 2.0 volume groups, both for
data and the cluster lock. See “About LVM 2.0” (page 38).
• Serviceguard now supports cell OL* (online addition and deletion of cells) on HP
Integrity servers that support them).

white paper HP Serviceguard Cluster Configuration for HP-UX 11i or Linux Partitioned
