very low. Test very low settings carefully to fine-tune all timing
parameters, and do the tests in an environment that imitates the actual
production environment as closely as possible.
Quorum Server Parameters in Cluster Configuration
You need to set values for Quorum Server parameters in the cluster
configuration file. Use a command such as the following to obtain a
cluster configuration file that includes Quorum Server parameters:
# cmquerycl -q <QS_Host> -n <Node1> -n <Node2> -C
<ClusterName>.config
The resulting file contains the QS_HOST, QS_POLLING_INTERVAL, and
QS_TIMEOUT_EXTENSION parameters. Serviceguard calculates the default
Quorum Server timeout on the basis of Serviceguard parameters,
including NODE_TIMEOUT and HEARTBEAT_INTERVAL. If you experience
Quorum Server time-outs, you can use the QS_TIMEOUT_EXTENSION
parameter to increase the Quorum Server timeout.
NOTE Increasing this value will increase the failover time accordingly; that is,
if failover time is currently 30 seconds and you set
QS_TIMEOUT_EXTENSION to one second, the failover time will increase to
31 seconds.
