VMware shrink an RDM and associated windows partition

EE,

I shrunk an RDM to 2TB so I can put it in virtual mode to prepare for an RDM to VMFS migration via sMotion. The only part that worries me is that even after removing the RDM from windows, deleting from disk and reattaching, the old 5TB size still exists.

How would I make the windows NTFS format recognize the new smaller size?

Thanks for reading

You need to shrink the OS Partition first!

Unless you have Snap manager for NetApp

How would I shrink the OS partition? I think that's what I'm asking. The RDM is already resized.

We have all the snapmanager licensese but I don't see anything called snap manager for netapp

Well Snapmanager installed in the OS!

You should shrink the OS partition first, either by using DIsk Management in the OS, or using a third party utility.

some third part apps, are listed in my EE Article

HOW TO:  Resize a VMware (VMDK) Virtual Disk

and once the Partition OS is shrunk, and re-sized, then shrink the RDM!

Wow all I did was just "shrink" the volume in computer management. Once it was shunk, I simply extended the volume with a right click and windows automatically reduced the size to reflect the NetApp RDM. All the data is there. No crazy tools involved.
