Implement an Action Plan and Solution Including Potential Effects
After identifying a cause, but before implementing a solution, you should develop a plan for the solution. This is particularly a concern for server systems in which taking the server offline is a difficult and undesirable prospect. After identifying the cause of a problem on the server, it is absolutely necessary to plan for the solution. The plan must include details around when the server or network should be taken offline and for how long, what support services are in place, and who will be involved in correcting the problem.
Planning is a very important part of the whole troubleshooting process and can involve formal or informal written procedures. Those who do not have experience troubleshooting servers might be wondering about all the formality, but this attention to detail ensures the least amount of network or server downtime and the maximum data availability.
With the plan in place, you should be ready to implement a solutionthat is, apply the patch, replace the hardware, plug in a cable, or implement some other solution. In an ideal world, your first solution would fix the problem, although unfortunately this is not always the case. If your first solution does not fix the problem, you will need to retrace your steps and start again.
It is important that you attempt only one solution at a time. Trying several solutions at once can make it very unclear which one actually corrected the problem.
