We've decreased 2 LUN's which is mapped to a Windows 2008R2 cluster (FC), from 200GB to 50GB.
What do I need to perform on the Windows level in order to get the new decreased size? Do I have to create a NEW smaller disk (50GB, the new size), map it to the server and manually copy all the data from the old decreased LUN, or is there a more elegant way?
BTW, needless to say that rescanning the disks within disk management on the server does not show the decreased size.
Thanks in advance
