Managing HP Serviceguard A.11.20.20 for Linux, March 2014

cluster configuration template file created by means of the cmquerycl command, as described
under “Configuring the Cluster” (page 153).
NOTE: See “Reconfiguring a Cluster” (page 225) for a summary of changes you can make while
the cluster is running.
The following parameters must be configured:
CLUSTER_NAME The name of the cluster as it will appear in the output of
cmviewcl and other commands, and as it appears in the
cluster configuration file.
The cluster name must not contain any of the following
characters: space, slash (/), backslash (\), and asterisk (*).
NOTE: In addition, the following characters must not be
used in the cluster name if you are using the Quorum Server:
at-sign (@), equal-sign (=), or-sign (|), semicolon (;).
These characters are deprecated, meaning that you should
not use them, even if you are not using the Quorum Server.
All other characters are legal. The cluster name can contain
up to 39 characters.
CAUTION: Make sure that the cluster name is unique
within the subnets configured on the cluster nodes; under
some circumstances Serviceguard may not be able to detect
a duplicate name and unexpected problems may result.
In particular make sure that two clusters with the same name
do not use the same quorum server; this could result in one
of the clusters failing to obtain the quorum server’s
arbitration services when it needs them, and thus failing to
re-form.
HOSTNAME_ADDRESS_FAMILY Specifies the Internet Protocol address family to which
Serviceguard will try to resolve cluster node names and
Quorum Server host names. Valid values are IPV4, IPV6,
and ANY. The default is IPV4.
• IPV4 means Serviceguard will try to resolve the names
to IPv4 addresses only.
• IPV6 means Serviceguard will try to resolve the names
to IPv6 addresses only.
• ANY means Serviceguard will try to resolve the names
to both IPv4 and IPv6 addresses.
IMPORTANT: See “About Hostname Address Families:
IPv4-Only, IPv6-Only, and Mixed Mode” (page 88) for
important information. See also the latest Serviceguard

QS_HOST The fully-qualified hostname or IP address of a host system
outside the current cluster that is providing quorum server
functionality. It must be (or resolve to) an IPv4 address on
Red Hat 5. On SLES 11, it can be (or resolve to) either an
