Unable to change Storage server Details

[kasvis]

A weird issue with the storage sevrer configuration

I had configured the storage servers for IP address initially using the command...

nbdevconfig -creatests -st 9 -stype DataDomain -storage_server 10.1.1.1 -media_server nbmedia

and then added the credentials using tpconfig...

However, now i want to change the to use DNS name for the storage servers instead of the IP address (10.1.1.1)..Then i deleted(both storage server entry and the credentials) and recreated using the above command, but with DNS name..Even after the recreation, the storage severs shows up with IP address in the netbackup console.Looks like it is taking something from the cache somewhere...Any ideas on what needs to be done here?.

I did delete the information from EMM database with the command.

nbemmcmd -deletehost -machinename 10.1.1.1 -machinetype ndmp

And then recreated them with DNS and it is working

PLEASE use hosts entries rather than relying on DNS.

The DataDomain Admin Guide recommends the following:

Follow these recommended practices:
• To avoid the need for frequent DNS lookups, add every media server host/IP address to the Data Domain system using the
net hosts add ipaddr {host | "alias host"}...
command.

• To avoid DNS lookup for every OST job, also add the Data Domain system IP address into the media server’s /etc/hosts file.
