Hello experts:
I am weighing in benefits of SQL Fail-over clustering and wondering the following when it comes to SQL patching (be it security patches of service packs, etc):
The main question is whether fail-over clustering can save us from any issues that might arise due to a patch. Suppose we have a 2 node fail-over SQL cluster and we want to apply a service pack. If we patch the passive node and fail-over our instance to the patched node and notice issues, would our instance be effected by the patch once it is failed over? Can we recover by failing the instance over to the unpatched node?
Thank you!
