Move Master Server to new DNS zone

Hi Guys,

 

We are looking at migrating an old legacy DNS zone to the main DNS zone. Our Master server is currently located in the legacy DNS zone.

 

Is there anything I need to look out for when migrating the Master server between DNS zones?

 

The Server name and IP will remain the same, obviously the FQDN will change but otherwise it will remain the same. Clients are configured to only use the hostname of the Master server, there might be a couple that use the FQDN but these can be changed as required.

 

Current config:

Netbackup 7.1.0.3
Solaris 10 Master/Media Server - Tape Library and Staging Disks connected. - located in the legacy DNS zone
Windows 2k8 Media/Storage server for Deduplication. - located in the Main DNS zone

 

Thanks

Dan

How is NBU configured? Shortname or FQDN?

Run nbemmcmd -listhosts -verbose

If master is showing shortname, all is well.

If FQDN, use nbemmcmd to add alias for shortname.

Thanks Marianne,

 

The MachineName and FQName are both set to use the FQDN.

Once I add an alias for the shortname, will I have to remove the old FQDN once we migrated zones?

If you don't mind - please show us output of nbemmcmd -listhosts.

Feel free to change names e.g. master.domain for FQDN or master for shortname.

Hi Marianne,

 

Here are the results, I've changed the names to MasterServer.domain and MediaServer.domain

There was no short name mentioned anywhere.

NBEMMCMD, Version:7.1
The following hosts were found:
server             MasterServer.domain
master             MasterServer.domain
ndmp               MasterServer.domain
media              MediaServer.domain
ndmp               MediaServer.domain
Command completed successfully.

I was hoping to see something like this:

MasterServer
        MachineName = "MasterServer"
        FQName = "MasterServer.domain"

 

Life is a lot easier in a situation like this...

In all honesty, I am no longer sure that this can easily be fixed with EMM aliases. It might be perceived as a hostname change.

I will ask my 'expert friends' for their thoughts and advice... Let me 'call a friend'...wink

This does look like a server name change to me so would need catalog / EMM manipulation

Having said that if you have a hosts file entry on the Master server for MasterServer.Domain against it IP address then it will tick along happily without any issues

Likewise hosts files can be used on the Media Servers for them selves and the Master - and I guess the clients may need ones for the Master and Media Server

Hope this helps

The Master server is configured with the FQN for the NBU name …

We treat this as the hostname, so as far as I know changing the domain is the 'same' as changing the hostname, and therefore unsupported.

It can possibly be done as a 'consulting' task by one of our 'Partners' ,  but not be Technical support - we are not allowed to do it, and, do not have access to the scripts used by the consultants.

Sorry for the late reply, been off work for a week. Thanks for the replies everyone.

 

If the server does get moved and we do try adding the host file entry as Mark suggested, what is the worst case senario if it doesnt work? Do we just move the server back and everything is fine or do i need to move it back and restore the catalog?
