How do I change the veritas cluster configuration manually?
-
You may want to change the vcs configuration manually for easy and speed of editing, rather than using the GUI
Note: The GUI allows you to change the configuration while the HAD daemon is running. Using the manual method you must first stop HAD daemon, the service will keep on running.
Stop the HAD daemon and keep the applications running
# hastop -all -force
Make a copy of the main.cf for saftey purposes
Edit the main.cf file
Verify the configuration
# hacf -verify /etc/VRTSvcs/conf/config
Run hastart on the systems where you made the changes to main.cf
# hastart
Run a status on the cluster, you should see "local build" status followed by "running". After you see running, run hastart on the other nodes.
# hastart
You'll see "remote build" status, on running hastatus
Write the configuration to disk on all systems
# haconf -dump -makero
