Netbackup, /etc/hosts has old domainname in aliasname

Created: 13 May 2013 • Updated: 17 May 2013 | 8 comments
This issue has been solved. See solution.

On my NBU Master Server the hostname entry:

XXX.XXX.XX.XXX    nbu-master  nbu-master.old-companyname.com

I would like to update the domain to reflect the new company name.

I've been told that I don't need Symantec's consulting assistance since my Administrative Console only uses the short name.  I'm looking for confirmation that I can change the domain name portion in the alias seen above from the old company name to correspond to the new company name without any issues/problems.

How was NBU installed? With shortname or FQDN?

See output of:
nbemmcmd -listhosts -verbose

If shortname is listed as Master and EMM server, there is no problem with changing the alias in /etc/hosts.

Just remember to update hosts entry for master in all media server /etc/hosts files as well (if entry exists).

Marianne,

Thanks for the fast response. 

Since the output of the command (see attached text file) that you sent me has FQDN in it (master server=edmonton) I'm concerned that it seems NBU was installed with FQDN.  Please note that this is in direct conflict with the answer I received for a ticket that I opened with Enterprise Support (Case 04312297) so I am really worried.  Below is that answer quoted from the email that I recieved:

---------------------------------

Hello Roger,

If you open the admin console it shows the name of whatever was used in the top right corner of the window.
-------------------------------------------------------------------------

Please let me know if my concern is founded.

Thanks so much,

Roger

All looks fully qualified to me I am afraid!

Looks like you will need the services of a qualified Symantec partner to help you here.

Generally if you open a Windows Admin Console the name of the server is as it was installed but your output all looks Fully Qualified to me

I agree with Mark - everything shows FQDN as far as the master server name is concerned.
I guess 'nbemmcmd -getemmserver' will show us the same FQDN name.

NBU has no knowledge of the shortname. You cannot simply update /etc/hosts with new FQDN.

It would have been possible if nbemmcmd -listhosts output looked like this:

edmonton
        MachineName = "edmonton"
        FQName = "edmonton.nj.conexant.com"

Please send your Support engineer output of 'nbemmcmd -listhosts -verbose'  and 'nbemmcmd -getemmserver' and ask for confirmation of previous statement....

Marianne & Mark,

Thanks to you both.  Apparently the Symantec technician knows less than the two of you.  Now I have to go through the lengthy process of getting a quote & generating a PO to engage professional services.  Fun stuff.

Thanks again,

Roger

As expected:

bash-3.00# ./nbemmcmd -getemmserver
NBEMMCMD, Version:6.5.6

Checking with the host "edmonton.nj.conexant.com"...

Server Type    Host Version        Host Name                     EMM Server

Command completed successfully.

It shouldnt be a lengthy process if you talk to the right Partner to do the work - I am sure Marianne would agree with me there (obviously not pushing our services - LOL!)
