Hello Team,
Since you are using pacemaker which is an OS level cluster service the agent will need to be configured as per our cluster doc.
https://documentation.commvault.com/2023e/expert/4990_configuring_cluster_group_clients_for_non_veritas_clusters_unix.html
Ensure below:
====
Note: The host name of the cluster should not be used by any existing client in your CommCell environment.
If you want to specify the IP address of the cluster group, ensure that the IP address is static.
====
Ensure that the CS/MA can ping the Cluster VIP, the cluster VIP is used for initial communication and after that the process moves over to the active node in the cluster.
For data transfer the active physical node will communicate with the MA to run backup/restores.
Let us know if you have any further queries or concerns.
