Netbackup Appliance 5240 Hostname dependency

Hi, we are having netbackup appliance 5240 which needs to be configured as master&media. 

Netbackup Appliance : Master/Media Server 

Appliance Hostname : ApplianceA  (prod lan)

Netbackup Clients    : All clients and appliance have private vlan for backups (bkp lan) 

Query: Is there any way that we can setup hostname of appliance as Appliance A(prod lan) and we can configure Netbackup master server with ApplianceABKP (bkp lan) hostname ?

Means : master server : ApplianceABKP  but appliance name is ApplianceA ?

so that master can talk to all the clients using backup vlan. Main reason for the above requirement is the backup vlan is on private vlan and we can not open firewall between master and client for communication if we setup the Master Server as ApplianceA.

    You can have two hostnames, maybe an alias but lets discuss some environmental topics first.

    This backup VLAN, do you have a separate dns zone configured for it i.e. backup.mycompany.com or mycompany.bkp insted of company.com, or have you only configured another range of IPs for each client.

    What you need to think about is how NetBackup will communicate. If you have a dns configuration as mentioned above it is easy to install the master, media, clients using that domain suffix. When any components tries to communicate, it will look for the servername.backup.mycompany.com or servername.mycompany.bkp and find the backup VLAN IP addresses and not the production ones. 

    This is a crucial point to note because if you don't then NetBackup will just ask for servername, and it might get one or the other and it might pick the production IP instead of the backup IP.

    If you don't have this in place you'll need to maintain hosts files which is just nasty.
