Hi bhdrkzltn and davidmoline ! Thank you so much for your contribution.
It really seems that the Virtual Netbackup Appliance has to be marked as Master Server (role).
However, after setting network properties there is not possible to set the Hostname.
The command "Network> Hostname Set nb-appliance" ends with error output
nb-appliance.Network> Hostname Set nb-appliance
- [Info] The host name that you specify here can be a short name or a fully qualified domain name. Note that the short name always appears in the following places:
-- NetBackup Appliance Shell Menu prompts
-- Deduplication pool catalog backup policy
-- Default storage unit and disk pool names
After you finish configuring the appliance, you cannot change the host name until you perform a factory reset on the appliance.
Do you want to continue? [yes, no](no) yes
- [Info] Setting the hostname to "nb-appliance".
- [Info] It may take several minutes to validate the hostname, apply the hostname to NetBackup and restart the NetBackup processes.
- [Info] Restarting the web service. The NetBackup Appliance Web Console is not available until the restart is completed. The restart may take a few minutes.
- [Error] V-409-930-003: Cannot set the hostname "nb-appliance". An internal error occurred in Appliance. Check the logs to see the detailed reason.
Just for checking, there is output of the Hosts Show command
nb-appliance.Network> Hosts Show
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
77.77.77.19 nb-appliance.com
77.77.77.19 nb-appliance
Finally, I am sure, that DNS name is resolvable.
Guys, do you have any idea what means the error - "[Error] V-409-930-003: Cannot set the hostname "nb-appliance". An internal error occurred in Appliance. Check the logs to see the detailed reason."
