Unable to write to EMC DD

All of the jobs are failing with an 2074 error. All of my research points to 'Storage Pool' problems. I do not have any Storage Pools defined. Just one Storage Unit.

Here is the result of the only command that I have found that relates to a BasicDisk Storage Unit

C:\Program Files\Veritas\NetBackup\bin\admincmd>nbdevquery -liststs -U
Storage Server      : scfmfts001.ad.dcf.state.fl.us
Storage Server Type : BasicDisk
Storage Type        : Formatted Disk, Direct Attached
State               : UP
Flag                : AdminUp
Flag                : InternalUp
Flag                : SpanImages
Flag                : BasicStaging
Flag                : FragmentImages
Flag                : CatalogBackup
Flag                : Cpr
Flag                : RandomWrites
Flag                : FT-Transfer

The state is always UP, the error is always DOWN.

2/18/2015 7:43:38 AM - Error nbjm(pid=2480) NBU status: 2074, EMM status: Disk volume is down Disk volume is down(2074)

Am I missing something that is so obvious I can not see it?

HOWTO104903 directly talks about this error and causes. As the doc says, do you see any clues when running bperror -disk? 

Also this connect forum post talks about this error. In the end, the user downed the media server, with the media server down rebooted the Data Domain. Maybe a communication error?

did you check the diskpool and diskvolume status

/usr/openv/netbackup/bin/admincmd/nbdevquery -listdp -U

/usr/openv/netbackup/bin/admincmd/nbdevquery -listdv -U

are they also showing up?

if they are showing Down.. you need to make them up using nbdevconfig command

 

Command to change the state of the disk pool to "UP":

# nbdevconfig -changestate -stype PureDisk -dp Disk_Pool_name -state UP

Command to "Reset" a disk pool:

# nbdevconfig -changestate -stype PureDisk -dp Disk_Pool_name -state RESET

How is Netbackup connected to the Data Domain - via CIFS,NFS, or DD BOOST or even VTL ???

Knowing this will help us a lot.

Could it be defined as a AdvancedDisk instead of a BasicDisk ?

Alternative provide the detailed job status from the activity monitor - some of use are quite good a guessing :)

>>Disk volume is down

 

run this command to check the disk(s)

nbdevquery -listdv -stype BasicDisk -U

BasicDisk, management is too cheap for the Advanced Disk

I really do appreciate all the help, I have used Netbackup/Backup Exec since Seagate days and this is the first time I have been completly stymied

I some of these commands whilst looking for answers. I am assuming the /usr/ means you are on a *nix box. 

I do not have 'disk pools'. I have one storage unit. Historically I had tape libraries which did not beat me up near as bad.

The bperror -disk returns a 'bunch' of

1424291986 1 1536 8 scfmfts001.ad.dcf.state.fl.us 0 0 0 *NULL* nbemm Volume EMC-DD:Internal_16 monitored by scfmfts001.ad.dcf.state.fl.us is down S{cl-2060017} 

Which means absolutely nothing to me.

I really miss my spell checker, not enought time to edit, fix, copy, paste.

Do certain replies get held for moderator apporval? I have show the results of the nbdevquery command twice and neither of them have appeared.

You can try this

Media and Device Management - Device Monitor - disk pools tab at the bottom of the page - UP the disk pool by right clicking on it

from this old thread

https://www-secure.symantec.com/connect/forums/datadomain-storage-server-down-backups-failing-code-213

 

== or CLI ==

nbdevconfig -changestate -stype BasicDisk -dp EMC-DD -state UP

( pretty sure that is CASE-sensitive )

That pane is empty. There are no 'devices' like I am accusomed to. Tape Drives, Robots, Changers. All I have is a Storage Unit with the CIFS.

I have no disk pools either, just one poor, little, lonely storage unit. I can read and write to it from the OS but it is not reflected anywhere in the device manager.

I was accustomed to the 'if the system does not see it, nb can not write to it'. But that was talking about physical devices. I just have the BasicDisk.

Ah right, sorry, with BasicDisk you won't see it there in the GUI.  Try the CLI command.

Nicolai has identified the problem!
(missing the 'thumbs up' button... )

The NBU services on the media server must have write permission on the UNC path.
(See TECH58780 for details)

I had run the command line and it reported success. Then I ran the query and it still shows as down.

Therein lays the rub. The Data Domain is not in our Active Directory Domain and I do not have administrative rights to it. Not that I would know what to do with it if I did. I can read/write to the UNC with my credentials. It is my understanding that anything coming from the IP address of the server can write to the UNC.

I guess I could write a quick and dirty program that rights to the UNC and run it under the system credentails and see what happens.

Very puzzling.

Everyone, Thank you, this was a major thorn in my side that has been removed.
