Connection problems between DataDomain applicance and Netbackup Media server
I have a problem with one of the DataDomain appliances.
From the media server I can navigate to it no problem:
DD560DR1:/backup 16599559680 10510207488 6089352192 64% /dd/DD560DR1/backup
DD560DR1:/ddvar 82569920 6606656 71768960 9% /dd/DD560DR1/ddvar
[root@eslin201 /]# cd /dd/DD560DR1/backup
[root@eslin201 backup]# ls
ddms exchangeHQ mercury mercuryHQ netbackupHQ test unix565hq2 windows windows565hq2
dev legacy_dev mercury2 netbackup sapHQ unix565hq1 vmware windows565hq1
[root@eslin201 backup]# pwd
/dd/DD560DR1/backup
But when I try and run a backup in Netbackup to this device I am getting this error in Netbackup:
27-Jul-2010 10:08:40 - Error nbjm (pid=4522) NBU status: 2074, EMM status: Disk volume is down
Disk volume is down (2074)
All other backups across this media server to normal disk pools and tape are working fine.
Netbackup v6.5.6 on Redhat v2.6

Well it is working again now.
I downed the media server, with the media server down rebooted the Data Domain, restarted back the media server, checked all of Netbackup processes running, mounted the Data Domain using normal Linux mount command and now my Data Domain Storeage units work OK.
When I do the 'nbdevquery -listdp' command the 'basic disk' Data Domain is not showed and I can only see my advance disk.
No real idea what was wrong which is frustrating, will speak to the engineer who implemented the Data Domain into Netbackup and ask him. Will feed it back to the forum if he gives me a decent explanation.
Many thanks for the replys
