Media server: Window2008 X64, NBU7.5.0.3  , 10.76.12.XX

Data domain : 10.76.12.YY

Media server can access and write to data domain cifs share \\10.76.12.YY\\mtree_blxecnbumast_exch01

now I created backup policies and start it manually but it always show me  "Disk volume is down(2074)" error.

Please show us Storage Unit config. Run this command on the Master server:

bpstulist -label <STU-name> -L

Please also check Service logon accounts on the media server for these 2 services: 
Netbackup Client Service and NetBackup Remote Manager and Monitor Service. 

Change both services from LocalSystem to a domain account with write permissions on the share.

Next, confirm comms between master and media server with these commands on the master:

nbemmcmd -listhosts -verbose

nbemmcmd -getemmserver

2) all the NBU services are running with domain account svc.exchangerepmgr instead of local system

3) I log in media server via domain account svc.exchangerepmgr and I can write to the Data domain cifs share......but it prompt for username/password at the first time

4)both the "nbemmcmd -listhosts -verbose " and  "nbemmcmd -getemmserver" completes successfully

[root@blxecnbumast ~]# nbemmcmd -getemmserver

on what user account Netbackup services are running on Media sever?

does that user account have the access to  DD CIFS share?

does the access provided in DD CIFS level?

i undestand when you try to access the share, it used the login accout that you used or it will ask for authentication..

but with netbackup try to access the Share, it used the on what account netbackup servvices are running.

so make sure that the accout that is running for the Netbackup services is having the access to the DD CIFS share and check agian..

Ah you 're right I think.

all the NBU services are running with domain account svc.exchangerepmgr...

I think I need to create the same account on datadomain.............

This means the user svc.exchangerepmgr does not have right to access DD.

I believe DD can not use Domain authentication. Create local user for CIFS access on both media server and DD with same user name and same password. Make sure this user is in local administrator group.

yes, you are right.
