Replacing a Failed Quorum Server System
Chapter 128
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(es) and hostname(s).
NOTE If you have configured the cluster to communicate with the Quorum
Server on more than one subnet, the new Quorum Server must be
able to communicate with all cluster nodes on both subnets, using
the same IP addresses as the old.
3. Install and configure the Quorum Server software on the new
system.
Be sure to include in the new Quorum Server authorization file all of
the nodes that were configured for the old Quorum Server; see
“Creating and Updating the Authorization File” on page 26.
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” on 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
