Howto unconfigure a cluster

[Zahid_Haseeb]

Environment

OS = Solaris10

HA = 6.0

There is a way to configure the cluster like run the ./installer from the setup and then select  option C to configure the HA like this ( " C) Configure an Installed Product " )

My Query:

Is there a way to unconfigure the cluster. I want to remove all HA configuration from a specific node and make this like , this node never had HA configured.

I don't think there is a wizard for this in UNIX (like I beleive there is for Windows), but it is fairly straightforward:

1. Remove system from main.cf and llthosts on all nodes and edit gabtab appropiately (normally "-n num_of_nodes")
2. Uninstal software on node removing
3. Remove llttab, llthosts, gabtab, etc/VRTSvcs/conf/* and /var/VRTSvcs/log/* if they exist

If you want to do this online, then you will need to use ha commands to remove system (hasys, hagrp etc) from main.cf

Please take all nessary data backup and if you are sure then run the following uninstall scripts from the location.

# cd /opt/VRTS/install
# ls
bin                  installsfcfsha       installvm            uninstallfs          uninstallsfsybasece
installdmp           installsfha          logs                 uninstallsf          uninstallvcs
installfs            installsfsybasece    showversion          uninstallsfcfsha     uninstallvm
installsf            installvcs           uninstalldmp         uninstallsfha
# ./uninstallsfha ====>>> Example

i think it may uninstall package - which is different than unconfigure.
