The possible causes for the CVM group being offline after adding a node to the cluster are as follows:
The cssd resource is configured as a critical resource in the cvm group.
Other resources configured in the cvm group as critical resources are not online.
To resolve the issue if other resources in the group are not online
# hares -online resource_name -sys system_name
# hastatus -resource resource_name
# haconf -makerw # hares -modify resource_name Critical 0 # haconf -dump -makero
