There are many commands and tools useful for detecting the problem and solve them. Also, there may be a hardware-level issue. In case of a network-related issue, we should do a ping to the server or if any automated ping-script configured, we should see it’s result.

As this is a huge topic, so I have written this in a series of articles where it’s importance, case study, DR steps, various types, DR demo, third party DR service are given. For more questions, connect with me on LinkedIn . What is disaster recovery (DR)?
