    Hi rookie11 

    Are the Netbackup services running on apdp01 ?

    Looks like network connectivity is missing.

    What about ping to apdp01 ?

    apdp01:/usr/openv/netbackup/bin/admincmd # ./nbemmcmd -getemmserver
    NBEMMCMD, Version: 8.2
    Failed to initialize EMM connection

    i ran nbemmcmd -getemmserver on master server.  
    [root@master admincmd]# ./nbemmcmd -getemmserver
    NBEMMCMD, Version: 8.3.0.1
    These hosts were found in this domain: apdp01, apdp02, apdp03, master 
    Checking with the host "apdp01"...
    Checking with the host "apdp02"...
    Checking with the host "apdp03"...

    nthing... it is not connecting to any media server\NBU appliance


    apdp01:/usr/openv/netbackup/bin # ./nbcertcmd -checkclockskew
    The current host clock is in sync with the master server.

    I may be wrong, but I think running nbemmcmd -getemmserver on a media server it will fail, since it's not a master server.

    I still suspect communication is broken between master and media server, use tcpdump or wireshark to verify.
    or
    Netbackup media processes isn't running on apdp01.

    Have you restarted the services on apdp01 ?

    Netbackup media processes isn't running on apdp01.  -- yes.

    Have you restarted the services on apdp01 ?  -- service recycle done 

    I think running nbemmcmd -getemmserver on a media server it will fail --  let me check this on different DC

      In your very first reply, you ran nbcertcmd -getcacertificate. Perhaps I missed it but did you re-issue a token as well?
