Planning Fault Tolerance and Avoidance for Cluster


Microsoft Windows 2000 Server, and especially Advanced Server with its clustering support, provides an excellent environment in which to build a truly fault-tolerant system. Of course, avoiding the faults in the first place is even better than handling them once they’ve happened, but the realistic system administrator knows that a problem will occur sooner or later and he or she can plan for it. Chapter 33 (from “Microsoft Windows 2000 Server Administrator’s Companion”, published by Microsoft Press) covered disaster planning in depth, so you should refer to that chapter for information on how to prepare for major problems and how to build a full disaster recovery plan to quickly resolve them.

 

A typical cluster issue includes one or more of the following symptoms:

 

1. Quorum disk is not accessible

2. Cluster service cannot start

3. Network access loss

4. Cluster setup problem

5. Cluster resource failure

6. Cannot fail over cluster resource
