This could be a fully qualified domain name issue

If it does not already exist create the netbackup\logs\bpcd\ folder on the media servers and try to connect again so that we can see what is logged

You may need to add or edit the hosts files on the Master and Media Server to ensure that short or FQDN are specified

Post the bpcd logs so that we can see what is happening

I wonder if this might be causing your problem?

Host file entries are not being used after upgrading to NetBackup 7.0.1

To support IPv6 (in NetBackup 7.1), NetBackup 7.0.1+ has changed from using the gethostbyname API to using the getaddrinfo API. On some platforms (see above), the name services switch database that determines gethostbyname behavior ('hosts') is different from that of getaddrinfo ('ipnodes').

For the hostname lookup override to work correctly in NetBackup 7.0.1+, the user must configure 'files' to have highest precedence for 'ipnodes', similar to 'hosts', in the /etc/nsswitch.conf.

        hosts:          files <other name services>
        ipnodes:        files <other name services>

Supporting Storage Foundation and VCS on Unix and Windows as well as NetBackup on Unix and Windows

When EMM doesnt receives connection from media server, there are possibilities for EMM to show Media server as OFFLINE.

  1. Stop the Netbackup service
  2. Stop PBX - "/opt/VRTSpbx/bin/vxpbx_exchanged stop"
  3. Start PBX - "/opt/VRTSpbx/bin/vxpbx_exchanged start"
  4. Start the Netbackup service.

- Also check the bp.conf file.

- Try running 'vmoprcmd -activate_host -h <media server name>' on the master server.

- Kindly post o/p of below command

<install path>\verits\netbackup\bin\admincmd#nbemmcmd -getemmserver

if NBU4 shown offline in above command then check connectivity between master & NBU (put FQDN in to host file)

Thanks you all. Its is pure realted to FQDS. In netbackup 7.1 its started to read /e/hosts file instead of domain server. We have removed the master server entries from /etc/hosts and reloaded the netbackup. Its working fine. Sorry for the late reply.

 Thanks and regards,
