Cross Cluster Quorum Server Configurations

7 10/7/2004

On node D, apply the configuration and start cluster2:

# cmapplyconf -P /etc/cmcluster/qs-pkg-1/qs-pkg-1.config

# cmruncl

C. Reconfigure cluster1 as a two node cluster that uses the Quorum Server package on

cluster2.

[On node B]

Halt cluster1:

# cmhaltcl –f

Edit the cluster ascii file and uncomment the lines for node A to make cluster1 into a two node cluster.

Notice that the FAILOVER_OPTIMIZATION (for SGeFF) is being enabled too:

# cd /etc/cmcluster

# vi cmclconf.ascii
