Re: reasons to bring down cluster
1) Changes to shared storage.
2) Updates that impact Service Guard.
3) Loss of hardware risks data corruption (precautionary, SG still runs but the risk is too high to remain in operation)
Neither is mandatory but the purpose of clustering is to avoid other down time issues.

Re: reasons to bring down cluster
Generally the must be halted if you want to change:
Timing Parameters
Cluster lock configurations
Changing IP address
Changing serial device files
That's all I can think of real quick....

Moving the data center
Testing to ensure your cluster will start up everything as it should properly.
