Media Server showing as Client
NetBackup v8.2
Issue: Virtual media server appliance showing as 'Client' under Host Properties > Media Servers, disk are seen as Offline (not Active for Disk)
4x virtual media server appliances, appliances 1 and 2 performing as expected, applianace 3 and 4 seen as 'Client', disks offline.
Troublshooting Steps Taken:
1. bpdown, bpup on both master and media servers
2. Confirm media servers are listed in Additional and Media Servers under Master server properties > Servers
3. Check registry settings, identical between all four servers
4. nbemmcmd -listhosts lists all four media servers, hosts tagged as 'media', ndmp entries also exist for all four servers
5. Run command 'nbemmcmd -updatehost -machinename <mediaserver hostname> -machinetype media -machinestateop set_disk_active -masterserver <masterserver hostname>' nothing happens
6. Advanced Disk and Pure Disk pools exist for all four servers, all same type/size
7. bpgetconfig -g <Working Media Server> reports working media server as 'Media Host'
8. bpgetconfig -g <Broken Media Server> reports broken media server as 'Client of <NetBackup Master>'
If anyone has any suggestions that would be very much appreciated!
