NetWorker start problem after upgrade from 8.2 to 9.2

Hello folks,

I just updated a NetWorker Server on a Windows 2008 Server from 8.2 to 9.2 which went through without any failure message.

Then I started the NetWorker processes. All processes came up and I could connect with the NMC. But I realized that I could not start any backups. The workflow will start but than hangs forever and does nothing. The daemon.log states a few messages:

14:21:09  2 12 13 3392 7164 0 <nw-server> nsrexecd GSS warning Group membership for "SYSTEM@NT-AUTHORITY“ cannot be verified and will not be included in the user's authentication credential. Remote hosts may not see the user as belonging to any operating system group.

Especially the ones I highlighted got my attention.

The NetWorker Server is now doing the index checks of all my clients but always comes back with "Program not registered".

When I try to start a backup from PowerShell or start a mminfo, I always get "Program nor registered".

I checked the DNS which is alright, I checked the local host-file which is also good.

Has anyone an idea what could bring NetWorker all the way up?

Thanks in advance,

beacon.

Re: NetWorker start problem after upgrade from 8.2 to 9.2

Which processes are running?

It might be that nsrmmdbd is missing. It might have been started but it might also have died already.

If so, all the ones which are supposed to start later will be missing as well due to these dependencies.

Run

  tasklist | findstr nsr

to verify that

I personally would proceed as follows:

  - stop all NW daemons

  - delete/rename the client related GSS database (..\nsr\res\nsrladb)

  - start NW again

Then test the connection with the good old method before you run any backup

  nsradmin -p nsrexec -s <nw_client>

I hope that you have not changed the hostname as well. If so, most likely the

  -  ..\nsr\res\servers file needs to be edited              AND

  -  the NW client daemon needs to be restarted

Then, before running any workflow, I would start a manual backup at the client:

  save -s <nw_server> -b <poo>l <whatever_path_you_want_to_backup>

Re: NetWorker start problem after upgrade from 8.2 to 9.2

I was able to witness this error once when NetWorker services were bounced, Try to run nsradmin -p nsrexecd -C -y "nsr peer information" and let it finish.

Hit a Backup with debug and share results.

Re: NetWorker start problem after upgrade from 8.2 to 9.2

Thanks everyone,

I involved EMC tech support and they were not able to resolve the issue.

The problem was that all NetWorker services started, except the nsrsnmd. No way to bring it up.

So I did a disaster recovery on the machine and installed NetWorker v9 on a new system with the same name.

But thanks anyway for the help!
