CORBA communication error (195)

after i have upgraded my netbackup master from 6.0MP5 to 6.5 then to 7.5 and upgrading of the Netbackup master server completed successful .

But when i reboot the HP unix media server which is still running on 6.0MP5 media server with tape storageunit the status of the media server is showing active for disk only when i run a nbemmcmd -listhosts -verbose.

So i have tried to run a nbemmcmd -getemmserver from the affected hp unix media server and i got this output showing below. I have also checked that the port 1556 , 13724 and 13722 is open between master bi-directional using the telnet.

NBEMMCMD. Version:6.0MP5(20060530)
The function returned the following failure status:
CORBA communication error (195)
Command did not complete successfully.

Might just be quicker to upgrade the media servers than investigate this.

To be honest, I agree it should be working, but these are an old level, and any backup environment is best it everything is up-to-date.

6.x  is out-of-support soon, so I'd just upgrade them - hopefully this will resolve the issue.

I don't think a media server

I was thinking it might be compatability, but having just checked ..

 

"Backward Compatibility"
NetBackup 6.x client and media server are supported with NetBackup 7.x servers. See Article TECH70729 <http://www.symantec.com/docs/TECH70729> for
NetBackup 6.x OS Software Compatibility List.

yes i have checked this.

OS is not the issue at this point and i have also checked the netbackup can have a mixed of 6.X for media and client .

Yuu mention port  1556 ,

Yuu mention port  1556 , 13724 and 13722

I think you mean 13724, which should be bpcd, not 13722 - however, I think this is not the cause of the issue.

nbemmcmd -listhosts on the media server will connect to pbx on the EMM server, I would check this log.

Please run these two commands

Please run these two commands on the master and post output?

nbemmcmd -listhosts -verbose

nbemmcmd -getemmserver

These commands will attempt to connect to all media servers and produce output received from media servers.

But strange is that my unix_media01 and 02 are currently running as 6.0MP5 but the nbemmcmd -listhost output is showing only 6.0. can i ignore this?

Probably ok, I uspect it's just reporting the base level - that is 6.0

Does 'nbemmcmd -listhosts

Does 'nbemmcmd -listhosts -verbose' report same versions on media server?

 

i need to check it .

I do also having issue on the win_media01 upgrade to nbu 7.5.0.1 which i have posted on another link . So this stopping me for upgrading the unix media server to 7.5.0.1 . Till i have resolved the win media server which already upgrade to 7.5.0.1.

I will check on the nbemmcmd -listhost -verbose on the win and unix media server again .

Thanks for you advise .

We see this lots of times

We see this lots of times with upgrades between versions...

The only way that I have found to fix it is to troubleshoot as if new installation...

Exactly same

Hello same Issue Here?

  In Upgrade Portal

 

In Upgrade Portal sort.symantec.com, they say that mixed version of NBBU Master at 7.5 is compatible with 6.0 media servers.

But it doesnt happen in reality i found many facing the same issue after upgrades with mixed version of MAster at 7.5 and nedia at 6.0 on Windows Linux, Solaris.

I did gave a call to Symantec support. 

Their solution was to do a media server upgrade which is not possible as immediate solution.

My media servers are SAP production servers so the suggestion from Symantec not always helps.

What if my OS onthis media Server is not compatible for NBU 7.5. 

You dont get anny support only upgrade  is the solution.

 

I wish Symantec should add this to upgrade portal to avoid possible issues like this.

I have verified on my test environment .

I have verified on my test environment . this error will be resolved if upgraded to netbackup 6.5 at less.

Since you have followed

Since you have followed Martin's advice to upgrade, I have moved solution to his post.
