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 120
• You must be running a version of Serviceguard, and of Quorum
Server, that support this capability. See “Compatibility with
Serviceguard Versions” on page 12, and “System Requirements and
Recommendations” on page 10.
• All of the cluster nodes must be able to communicate with both of the
Quorum Server subnets when you configure or reconfigure the
cluster.
If this is not true when you run cmquerycl, cmcheckconf, or
cmapplyconf, the command will fail.
• Both of the IP addresses specified for the Quorum Server must map
to the same Quorum Server.
• The authorization file must specify all the addresses from which the
cluster nodes will communicate with the Quorum Server. See
“Creating and Updating the Authorization File” on page 26.
• You must halt the cluster in order to add a second Quorum Server
subnet to a cluster that is currently using only one.
Setting Quorum Server Parameters in the Cluster
Configuration File
You need to set values for Quorum Server parameters in the cluster
configuration file. Use a command such as the following (all on one line)
to obtain a cluster configuration file that includes Quorum Server
parameters:
cmquerycl -q <QS_Host> -n <Node1> -n <Node2> -C
<ClusterName>.config
NOTE If you are using a version of Serviceguard that supports alternate
subnets (see “Compatibility with Serviceguard Versions” on page 12), you
can specify a second hostname or IP address in the -q option (all one
line):
cmquerycl -q <QS_Host> <QS_Addr> -n <Node1> -n <Node2> -C
<ClusterName>.config
QS_Host and QS_Addr can each be either a fully qualified hostname or an
IP address.
