“What Happens when You Change the Quorum
Configuration Online” (page 43) for important
information.
QS_TIMEOUT_EXTENSION You can use the QS_TIMEOUT_EXTENSION to
increase the time interval after which the current
connection (or attempt to connect) to the quorum
server is deemed to have failed; but do not do so
until you have read the HP Serviceguard Quorum
Server Version A.04.00 Release Notes, and in
particular the following sections in that document:
“About the QS Polling Interval and Timeout
Extension”, “Network Recommendations”, and
“Setting Quorum Server 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 43) for important
information.
NODE_NAME The hostname of each system that will be a node
in the cluster.
CAUTION: Make sure that the node 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.
Do not use the full domain name. For example,
enter ftsys9, not ftsys9.cup.hp.com. A
cluster can contain up to 16 nodes.
