Red Hat Virtualization (RHV) VM discovery and backup and restore jobs fail if the Media server node that is selected as the discovery host, backup host, or recovery host is replaced
If the Media server is replaced with another node, secure communication between the new node and the NetBackup host is lost because the options configured for a secure connection in the bp.conf file are deleted. If secure communication is not established, RHV discovery, backup and recovery jobs start failing. (4005637)
Workaround:
Reconfigure the secure connection between the new node and the NetBackup host by configuring the security options that were set earlier in the bp.conf file.
