I will be adding a 2nd node into a Windows 2008 R2 cluster, and I need to present the shared disks from the SAN side first, then when I do validation tests, will those tests bring the shared disks offline? Our primary node is in production so that would not be good.
Node 1 is out of date in terms of "Windows Updates" never been patch.
Node 2 (not joined to cluster) has been updated recently.
I plan on updating Node 1 prior adding Node 2.
