HP Serviceguard A.11.20- Managing Serviceguard Twentieth Edition, August 2011

NOTE: Lock volume groups must also be defined in
VOLUME_GROUP parameters in the cluster configuration file.
Can be changed while the cluster is running; see “What
Happens when You Change the Quorum Configuration
Online” (page 49) for important information.
QS_HOST The fully-qualified hostname or IP address of a system outside
the current cluster that is providing quorum service to the
cluster. Can be (or resolve to) either an IPv4 or an IPv6
address if HOSTNAME_ADDRESS_FAMILY is set to ANY, but
otherwise must match the setting of
HOSTNAME_ADDRESS_FAMILY. This parameter is used
only when you employ a Quorum Server for tie-breaking
services in the cluster. You can also specify an alternate
address (QS_ADDR) by which the cluster nodes can reach
the Quorum Server.
For more information, see “Using a Quorum Server”
(page 99) and “Specifying a Quorum Server” (page 190).

Server” in the latest version HP Serviceguard Quorum Server

IMPORTANT: See also“About Hostname Address Families:
IPv4-Only, IPv6-Only, and Mixed Mode” (page 106) for
important information about requirements and restrictions
in an IPv6–only cluster.
Can be changed while the cluster is running; see “What
Happens when You Change the Quorum Configuration
Online” (page 49) for important information.
QS_ADDR An alternate fully-qualified hostname or IP address for the
Quorum Server. Can be (or resolve to) either an IPv4 or an
IPv6 address if HOSTNAME_ADDRESS_FAMILY is set to
ANY, but otherwise must match the setting of
HOSTNAME_ADDRESS_FAMILY. This parameter is used
only if you use a Quorum Server and want to specify an
address on an alternate subnet by which it can be reached.
The alternate subnet need not use the same address family
as QS_HOST if HOSTNAME_ADDRESS_FAMILY is set to
ANY. For more information, see “Using a Quorum Server”
(page 99) and “Specifying a Quorum Server” (page 190).
