Here are a few basic steps to help trouble shoot your NetBack up setup, primarily focused on the client side conf and issue testing.
When administering NetBack Up the key directory to look for on Unix and Linux systems is /usr/openv/netbackup/
The configuration file within that directory is bp.conf
That file will contain all the hostnames required for your particular NetBack Up installation to work.
— Connectivity Issues —
You can confirm your NetBackup functionality/connectivity
Test Master Host DNS name
Test Master Host IP Address
Test Client to Master Host connectivity
These few steps will help you identify where the break in your connectivity is, should one exist between master server and node.
— Service Issues —-
Obvious first step is to check the health of the service and restart it if giving trouble. Check logs, or if running an OS like RHEL7, check status.
— Error Codes —
The NetBack Up server will provide error codes when things go wrong. This will be a crucial reference to understand what is going wrong in your system.
