Question on patching with clusters
Posted on 2008-10-11
I have a query about clusters that I was hoping someone could help me with.
Let's say I have an Active/ Active/ Passive cluster (Windows 2003) formation for Exchange 2003.
How does this work if I want to install patches for
a) The OS
b) The application (i.e. Exchange)
In both cases, do I need to fail over Exchange to the passive node and then patch the node without the Exchange virtual server? Or does this apply only for OS patching, i.e. for application patching you need to patch the virtual servers itself?
Hope someone can help...I'm a bit confused by servers/virtual servers (not referring to Vmware virtualisation here btw)!
Max points for a good answer.
