HP Serviceguard Quorum Server Version A.03.00 Release Notes, December 2007

HP Serviceguard Quorum Server Version A.03.00 Release Notes
Configuring Serviceguard to Use the Quorum Server
Chapter 1 21
The resulting file contains the QS_HOST, QS_POLLING_INTERVAL, and
QS_TIMEOUT_EXTENSION parameters, and the QS_ADDR parameter if your
version of Serviceguard supports it. In that case, the Quorum Server
section of the file looks like this:
# for the quorum server timeout, enter
#
# QS_HOST qs_host
# QS_ADDR qs_addr
# QS_POLLING_INTERVAL 120000000
# QS_TIMEOUT_EXTENSION 2000000
QS_HOST gf2_qs1
QS_ADDR 15.106.73.114
QS_POLLING_INTERVAL 300000000
If your version of Serviceguard supports alternate subnets, but you are
working with an existing cluster configuration file that does not contain
the QS_ADDR parameter, you can add this parameter, and its value,
yourself.
CAUTION If you are adding an alternate Quorum Sever subnet to a cluster
currently using only one, you must halt the cluster to add the alternate
subnet.
You can use the optional QS_TIMEOUT_EXTENSION to increase the time
interval (in microseconds) after which the current connection (or attempt
to connect) to the quorum server is deemed to have failed; see “Network
Recommendations” on page 11.
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.
