Managing Serviceguard A.11.20, March 2013

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 104) and “Specifying a Quorum Server” (page 194).
See also “Configuring Serviceguard to Use the Quorum
Server” in the latest version HP Serviceguard Quorum Server
Version A.04.00 Release Notes, at http://www.hp.com/
go/hpux-serviceguard-docs under HP Serviceguard
Quorum Server Software.
IMPORTANT: See also“About Hostname Address Families:
IPv4-Only, IPv6-Only, and Mixed Mode” (page 111) 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 50) 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 104) and “Specifying a Quorum Server” (page 194).
IMPORTANT: For special instructions that may apply to
your version of Serviceguard and the Quorum Server see
