Managing HP Serviceguard for Linux, Tenth Edition, September 2012

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 100) for important information. See also the
latest Serviceguard release notes at
docs.hp.com under High Availability
—> Serviceguard for Linux.
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 10 and 11, it 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 “Cluster Lock Planning”
(page 96) and “Specifying a Quorum Server”
(page 182). See also “Configuring Serviceguard
to Use the Quorum Server” in the latest version
