MC Serviceguard - Replace Quorum Server

domingo, 26 de fevereiro de 2012

The first step is stop completely the cluster.. you can't do that without stop your cluster.

for each package:

# cmhaltpkg <package_name>

Stop the cluster:

# cmhaltcl

Now change the Quorun server:

# vi /etc/cmcluster/cmclconfig.ascii
...
QS_HOST quorum-server

Apply changes:

# cmapplyconf -v -C cmclconfig.ascii

Check the cluster configuration:

# cmcheckconf -v -C cmclconfig.ascii

Star the cluster again:

# cmruncl -v

Now check if the new quorum server is in use.

# cmviewcl -v
