Replacing a Failed Quorum Server System
Chapter 124
Replacing a Failed Quorum Server System
Use the following procedure to replace a defective Quorum Server system
without changing the configuration of any cluster nodes.
1. Remove the old Quorum Server system from the network.
2. Set up the new system and configure it with the old Quorum Server’s
IP address and hostname.
3. Install and configure the Quorum Server software on the new
system. Be sure to include in the new QS authorization file all of the
nodes that were configured for the old Quorum Server.
In HP-UX, the authorization file is /etc/cmcluster/qs_authfile.
In Linux Red Hat, the authorization file is
/usr/local/qs/conf/qs_authfile.
In Linux SuSE, the authorization file is
/opt/qs/conf/qs_authfile.
Refer to the qs(1) man page for details about configuring the QS
authorization file.
4. Start the Quorum Server as follows:
• Edit the /etc/inittab file to add the Quorum Server entries, as
shown in “Uninstalling the Quorum Server” on page 26 above.
•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 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
