Table Of Contents
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 42).
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 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 42).
Serviceguard now supports cell OL* (online addition and deletion of cells) on HP
Integrity servers that support them).
