HP Serviceguard Quorum Server Version A.04.00 Release Notes, March 2009

Edit the /etc/inittab file to add the Quorum Server entries, as shown in
“Installing the Quorum Server” (page 13).
•
• 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 17)):
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
can happen:
• These three commands will not work: cmquerycl -q, cmapplyconf -C,and
cmcheckconf -C.
• 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 qs
• To uninstall the Quorum server on HP-UX, use the swremove command:
swremove B8467BA
