How to Know the role of machine in Netbackup environment

Hello All,

How do I know that certain machine is Netbackup Master, Media Manager and client on Linux Operating system. Is this information is stored somewhere (in File Or some other place)

On windows, we get this information in registry key @"HKLM\SOFTWARE\Veritas\NetBackup\CurrentVersion", "Install Type"

Is this possible on Linux?

Thanks,

Omkar
