Administering VCS 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.
To administer a VCS service group
- Start the VCS engine on seattle1:
# hastart
- Verify that all the service groups that contain RVG resource type are brought online:
# hagrp -display
- Take the service group offline and verify that all resources are stopped:
# hagrp -offline hr_grp -sys seattle1
# hagrp -display
- Bring the service group online again and verify that all resources are available:
# hagrp -online hr_grp -sys seattle1
# hagrp -display
- Start the VCS engine on seattle2:
# hastart
- Switch the VVR service group to seattle2:
# hagrp -switch hr_grp -to seattle2
- Verify that all the service groups that contain RVG resource type are brought online on seattle2:
# hagrp -display
- Repeat step 1 through step 7 for the cluster London.
- 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
