HP Serviceguard Quorum Server for Linux Version A.12.00.00 Release Notes, March 2014

4. Start the Quorum Server as follows:
• Edit the /etc/inittab file to add the Quorum Server entries, as shown in “Installing
the Quorum Server” (page 7).
• Use the init q command to run the Quorum Server.
Refer to the qs(1) man page for more details.
5. All nodes in all clusters that were using the old Quorum Server will connect to the new Quorum
Server. Use the cmviewcl -v command from any cluster that is using the Quorum Server to
verify that the nodes in that cluster have connected to the Quorum Server.
6. The Quorum Server log file on the new Quorum Server will show a log message such as the
following for each cluster that uses the Quorum Server:
Request for lock /sg/<ClusterName> succeeded. New lock owners: N1, N2
7. To check that the Quorum Server has been correctly configured and to verify the connectivity
of a node to the Quorum Server, you can execute the following command from your cluster
nodes as follows:
cmquerycl -q <QS_Host> -n <Node1> -n <Node2> ...
or (if you are using more than one subnet; see “Using alternate subnets” (page 10)):
cmquerycl -q <QS_Host> <QS_Addr> -n <Node1> -n <Node2> ...
The command will output an error message if the specified nodes cannot communicate with
the Quorum Server.
While the old Quorum Server is down and the new one is being set up, these things may happen:
• Commands: cmquerycl -q, cmapplyconf -C,and cmcheckconf -C not working.
• If there is a node or network failure that creates a 50-50 membership split, the Quorum Server
will not be available as a tie-breaker, and the cluster will fail.
CAUTION: Make sure that the old system does not re-join the network with its old IP address(es).
Uninstalling the Quorum Server
To uninstall the Quorum server on Linux, use the rpm command:
rpm -e serviceguard-qs-A.12.00.00-0
