Server” (page 13) and “Setting Quorum Server Parameters in the Cluster Configuration
File” (page 14).
• If a subnet that connects the Quorum Server to a cluster is also used for the cluster heartbeat,
configure the heartbeat on at least one other network, so that both Quorum Server and
heartbeat communication are not likely to fail at the same time.
Compatibility with Serviceguard Versions
This version of the Quorum Server supports:
• Serviceguard clusters running Serviceguard 11.14 or later on HP-UX 11i v1, 11i v2 or 11i v3.
• Serviceguard clusters running Serviceguard 11.14 or later on supported Red Hat or SUSE
Linux distributions.
IMPORTANT:
• The alternate-subnet capability is available only for Serviceguard A.11.17 on HP-UX 11i v2
with patch PHSS_35427, and on HP-UX 11i v2, HP-UX 11i v3, and Linux for Serviceguard
A.11.18 (with October 2007 or later patch) and A.11.19. See “How the Quorum Server Works”
(page 8) for information about the difference in implementation between A.11.19 and the
earlier releases.
See the latest version of the corresponding Serviceguard A.11.18 Release Notes for required
patches for Serviceguard A.11.18.
• Quorum Server version A.04.00 is required if you are using an alternate subnet for
communication with a Serviceguard A.11.19 cluster, and must be installed before you
upgrade the cluster to A.11.19.
• If you are running Serviceguard A.11.19 and want to use an IPv6 connection, or connections,
between the cluster and the Quorum Server, you should apply the July 2009 patch to
Serviceguard. See the latest Serviceguard release notes for information about this patch.
The patch is required for IPv6-only clusters, but it is also possible to configure IPv6
connections without the patch; see “Configuring IPv6 Addresses without the July 2009 Patch”
(page 15) for instructions.
• You will need to apply Cluster Object Manger (COM) patch PHSS_35372 in order to use
the older, station-management version of Serviceguard Manager to manage a cluster that
uses more than one subnet for communication with the Quorum Server.
For complete compatibility information, see the Quorum Server Compatibility Matrix posted at
docs.hp.com -> High Availability -> Quorum Server.
Installing the Quorum Server
Read this entire document and any other Release Notes or READMEs you may have before you
begin an installation.
The Quorum Server software, which has to be running during cluster configuration, must be
installed on a system other than the nodes on which your cluster will be running. This could be
a single Linux or HP-UX system, or it could be a separate cluster.
If you are updating from an older version of Quorum Server, see the instructions below.
