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

Notables:
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.

Thanks,

Ryan
