Explain The Steps Involved In Offline Vcs Configuration?

Answer»
  • Save and close the configuration :
    # haconf -dump -makero
  • Stop VCS on all NODES in the cluster :
    # hastop -all
  • Edit the configuration file after taking the backup and do the CHANGES :
    # cp -p /etc/VRTSvcs/conf/config/main.cf /etc/VRTSvcs/conf/config/main.cf_17march
    # vi /etc/VRTSvcs/conf/config/main.cf
  • Verify the configuration file syntax :
    # hacf -verify /etc/VRTSvcs/conf/config/
  • start the VCS on the system with modified main.cf file :
    # hastart
  •  start VCS on other nodes in the cluster.

Note : This can be DONE in another way by just stopping VCS and LEAVING services running to minimize the downtime. (hastop -all -force GAB, LLT and HAD)
