Take drive offline prior to OS Updates....

Looking for a solution to break the mirror before installing OS Updates to mitigate failures and preserve baseline drive integrity.

Durning testing I can recreate a kernel failure that prevents booting the OS when the system experiences a power failured during this update. OS Update is KB954211, which is a kernel update. System failure is:
Windows could not start because the following file is missing or currupt. \system32\ntoskrnl.exe

There is no option for any manual mitigation: IE: I cannot have an on site technician remove the backup drive prior to installing the OS Updates.

I am looking for a solution that can be VB scripted to take the backup drive offline, install the updates, and bring the backup drive back online so it may mirror after successful install.
