master server is through DNS or host file entry

Hi,

How to check whether master server is through DNS or /etc/host/file.

Any command

NetBackup will use whatever the OS uses.

Depending on the OS, there might be a file called /etc/nsswitch.conf

Check in this files for 'hosts' entry. An entry like:

hosts  files dns

will 1st check local /etc/hosts file, then DNS.

So, to cut a long story short - you need to verify at OS level which method is used for comms.

PS: PLEASE give feedback on your cluster question in your other post.

How we can verify that?

In general if entries exist in the hosts file the O/S will look there first but NetBackup will look in its own cache before anywhere else

The NetBackup cache gets updated every so often (1 or 2 hours I seem to remember) so if you make any changes you need to flush the NBU cache for them to take effect:

bpclntcmd -clear_host_cache

Have you seen the following in my post above?
