Update VMWS user password in NetWorker database, using nsradmin tool in offline mode.
 

1. Stop NetWorker Service 
   1. On the NetWorker server, stop NetWorker services:

                    Linux: nsr_shutdown
                    Windows: net stop nsrexecd
                                   OR
                    Start > Run > type services.msc
                    Look for NetWorker Remote Exec Service and Stop it.
                   
                                                                                                                   
                    

1. 2. Confirm that all nsr services stop:

Linux: ps -ef | grep nsr
Windows: tasklist | findstr nsr
                                            

2. Make a copy of the NetWorker Media Database (mm) and Resource (res) folders:

Location of Folders:

Windows:

<Installation_Drive:\Program Files\EMC NetWorker\nsr\mm>
<Installation_Drive:\Program Files\EMC NetWorker\nsr\res\nsrdb>
                                           
 Example: C:\Program Files\EMC NetWorker\nsr\mm and  C:\Program Files\EMC NetWorker\nsr\res\nsrdb
                         

Linux:

Example: /nsr/mm and /nsr/res/nsrdb

3. Connect to NetWorker database in offline mode

D:\Program Files\EMC NetWorker\nsr\res>nsradmin -d nsrdb
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> . type: nsr
Current query set
nsradmin>

4. Update the password for VMWS user info in the nsrdb database (offline)

nsradmin> update VMWS user password:PutNEWpasswordHere
VMWS user password: *******;
Update? y
updated resource id 2.0.76.45.0.0.0.0.40.68.39.90.10.112.115.152(1482)
nsradmin> quit

5. Start the NetWorker Service

Windows: 

From Admin Command Prompt: net start nsrd
If the server is also an NMC server: net start gstd

Or:

Start > Run > type services.msc
Start NetWorker Backup and Recover Server.
If the server is also an NMC server, start: EMC GST Service

Linux: systemctl start networker
 

6. Open the NMC and verify that the issue is no longer occurring.
