Open storage(DataDomain)host name change

Hi All,

 

I have a backup setup with Netbackup 7.0.1 and DataDomain connected to it. It has been configured as Openstorage storage server. Backups are being taken to DD through OST  plugin. now i have a requirement to change my DataDomain's hostname as per our new standard.

 

* how do i change the new host name of DataDomain in Netbackup?

*if i change the DD hostname in netbackup, will i be able to restore my old backups?

*what are the settings to be changed to make sure my old backups are recoverable?

 

Can anyone help me?

 

Thanks,

Saravanan.
