Administering the Service Groups

This section explains how to administer a VCS service group for cluster Seattle from the command line. Note that you can also use the VCS Java and Web consoles to administer service groups.

1. Start the VCS engine on seattle1:
     # hastart
2. Verify that all the service groups that contain RVG resource type are brought online:
     # hagrp -display
3. Take the service group offline and verify that all resources are stopped:
     # hagrp -offline hr_grp -sys seattle1
     # hagrp -display
4. Bring the service group online again and verify that all resources are available:
     # hagrp -online hr_grp -sys seattle1
     # hagrp -display
5. Start the VCS engine on seattle2:
     # hastart
6. Switch the VVR service group to seattle2:
     # hagrp -switch hr_grp -to seattle2
7. Verify that all the service groups that contain RVG resource type are brought online on seattle2:
     # hagrp -display
8. Repeat step 1 through step 7 for the cluster London.
9. If required, check the following log files on any system for the status or any errors:

   /var/VRTSvcs/log/engine_A.log

   /var/VRTSvcs/log/RVG_A.log
