About communication with 8.0 or earlier host in multiple NetBackup domains
This section provides information on what is the impact of the option on the host communication when one of the NetBackup hosts is in multiple domains.
Consider the following scenario:
Host A is of version 8.1, which is present in multiple NetBackup domains called M1 and M2.
Host B is of version 8.0, which is present in a NetBackup domain called M3.
The option is cleared on master server M1, which means hosts that are associated with M1 cannot communicate with hosts that are 8.0 or earlier.
The option is selected on master server M2, which means hosts that are associated with M2 can communicate with hosts that are 8.0 or earlier.
The configuration file (bp.conf file on UNIX or registry keys on Windows) for Host A contains 'M2' as the first entry in the master server list.
When Host A initiates communication with Host B, the status of the option is verified for the first master server that appears in the configuration file of Host A, which is M2. As per the option set for M2, communication with 8.0 or earlier hosts is allowed. Therefore, communication between Host A and Host B is successful.
