Always good to provide some backgroud in addition to Job details.

Names of DAG members?
Name of Virtual (DAG)  hostname?
How is policy configured? (bppllist <policy-name> -U)
Is NBU installed on all DAG members?
Have you checked name resolution and port connectivity between media server(s) and all DAG members?

Please see this related forum post: 
https://vox.veritas.com/t5/NetBackup/39-client-name-mismatch/m-p/552217

and https://vox.veritas.com/t5/NetBackup/NBU-7-1-with-Exchange-DAG-2010-host-names/td-p/551430

In addition to the basic information requested by @Marianne...

  • What are the versions of NetBackup on servers and clients? What Exchange-related EEBs do you have installed?
  • What is the version of Exchange?
  • If Exchange is 2013 or later, is the DAG name resolvable in the DNS to an IP address? Seems to be yes, since the error came from bpcd on the DAG.
  • As always, when job details or bpbrm log reports an error from a client process, look at the client log.

The links @Marianne provided are a little old. One thing you should not have to do if you have NetBackup 7.7.3 or later, is to define your DAG and Exchange servers in any hosts files to compensate for an IP-less DAG.

By the time a backup job gets to bpbrm, the client name should not be a DAG name anymore. And it isn't:

>Info nbjm (pid=14779) starting backup job (jobid=754) for client SIMAOSVMBX01

>bpbrm (pid=72535) [PROXY] Connecting host: simaobkp01

Why two different client names, and why an apparent DAG name in the error?

>bpbrm (pid=72535) bpcd on DAG-SIMAO exited with status 39: client name mismatch.

There's a lot to be confused about here. Please provide the requested details.

yes NBU is stalled on all DAG member , all firewall are off and resolution work fine

 

I updated my post while you were posting. Your post underscores a question I forgot to ask:

Do you have custom hosts files that give IP addresses for the DAG and its mailbox servers? (Don't do that.) Some NetBackup processes use reverse lookup from IP address to host name. You can get a different name than you started with if you've defined the IP address in the hosts file.

i have add DAG and node server in host file  , only jobs that are running on  SIMAOSVMBX01 fail jobs that are running on SIMAOSVMBX01 are success

Do you think the media server simaobkp01 is the PROXY host?
(I thought the proxy host was only used during GRT list/restore.)

@brice1

You have listed SIMAOSVMBX01 twice - for successful and failed jobs?

oups!! sorry  SIMAOSVMBX01 for fail jobs and SIMAOSPMBX03 for success 

I don't know what the PROXY in the bpbrm logs means. It's not the Exchange granular proxy host. That only applies to bplist and bpduplicate, and any operations that imply bplist under the covers such as browsing in the restore GUI. The granular proxy host is resolved in bprd or bpdbm. It would not be known as a proxy in bpbrm or the processes it calls.

Clean up your hosts file. You should not use it to resolve your DAG or Exchange servers.

Example of hosts file abuse that matches your symptoms.

nnnnnnn mbx03 DAG

Forward look-up, DAG resolves to nnnnnnn. Reverse lookup nnnnnnn resolves to mbx03. Bpcd running on mbx01 compares mbx03 to the local host name and fails.

I could have the details wrong, but that's the idea.

@brice1

Have you had a look at hosts files yet and performed cleanup?

You never told us which versions you are using for :
NBU ? 
Exchange ? 
IP-less DAG or not? 

@Marianne@Lowell_Palecek I found an incorrect of client name  value in the registry, I changed with correct name and the backup and it works . thank you for your support
