Managing HP Serviceguard for Linux Ninth Edition, April 2009

hosts should contain the following entry:
::1 ipv6-localhost ipv6-loopback
For more information and recommendations
about hostname resolution, see “Configuring
Name Resolution” (page 150).
NOTE:
— ANY is not supported on Red Hat 5.
— ANY is not supported in a cluster that
includes Virtual Machines (VMs).
QS_HOST The fully-qualified hostname or IP address of a
host system outside the current cluster that is
providing quorum server functionality. Can be
(or resolve to) either an IPv4 or an IPv6 address
on SLES 10, but must be an IPv4 address on Red
Hat 5. 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. See also the entry
for HOSTNAME_ADDRESS_FAMILY later in
this section.
For more information, see “Cluster Lock
Planning” (page 98) and “Specifying a Quorum
Server” (page 173)
Can be changed while the cluster is running; see
“What Happens when You Change the Quorum
Configuration Online” (page 48) for important
information.
QS_ADDR An alternate fully-qualified hostname or IP
address for the quorum server. Can be (or resolve
to) either and IPv4 or an IPv6 address on SLES
10, but must be an IPv4 address on Red Hat 5.
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. For
more information, see “Cluster Lock Planning”
(page 98) and “Specifying a Quorum Server”
(page 173).
