Managing HP Serviceguard for Linux, Tenth Edition, September 2012

3. Install and configure the quorum server software on the new system. Be sure to

include in the new QS authorization file (for example, /usr/local/qs/conf/

qs_authfile) on all of the nodes that were configured for the old quorum server.

Refer to the qs(1) man page for details about configuring the QS authorization

file.

NOTE: The quorum server reads the authorization file at startup. Whenever you

modify the file qs_authfile, run the following command to force a re-read of the

file. For example on a Red Hat distribution:

/usr/local/qs/bin/qs -update

On a SUSE distribution:

/opt/qs/bin/qs -update

4. Start the quorum server as follows:

• Edit the /etc/inittab file to add the quorum server entries, as shown in the

latest version of the HP Serviceguard Quorum Server Version Release Notes.

• Use the init q command to run the quorum server.

• Create a package in another cluster for the Quorum Server, as described in

the Release Notes for your version of Quorum Server. They can be found at

http://docs.hp.com ->High Availability ->Quorum Server.

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 QS.

6. The quorum server log file on the new quorum server will show a log message like

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 <QSHostName> -n <Node1> -n <Node2> ...

The command will output an error message if the specified nodes cannot communicate

with the quorum server.

CAUTION: Make sure that the old system does not rejoin the network with the old IP

address.
