The DNS server cannot connect to the storage device as a result of the TCP port being disabled. Let's find below the process of rectifying that.
[Diagnostic]
The DNS server cannot connect to the storage device.
[Analysis]
Collected the logs and analyzed them. It is found that:
So, the error code 28003 showed the failed open port 53 when the storage connected to the DNS server.
We need to allow port the 53 from DNS and storage. From the storage side, it can also test the ping and Telnet from the storage. To check that, log in to the minisystem as per below and then execute 'ping 10.XX.XX.XX' 'telnet 10.XX.XX.XX 53'. Upon testing, 'ping 10.XX.XX.XX' should be alive and 'telnet 10.XX.XX.XX 53' should go through.
[Solution]
The TCP port is enabled and the DNS server is connected to the storage device.
