Data Backup and Recovery
When I click the button "Expand Disk..." to expand the lun with SnapDrive GUI, I got following error:
Unable to reseize disk. Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
SnapDrive Version: 7.1.4
OS: Windows Server 2016
Volume for the LUN is 250GB large.

Rebooting the Windows-Server solved the problem.
From SnapDrive created LUN's should be never changed with other tools like OnCommand System Manager or windows disk management.
These LUN's have have a special disk geometry from SnapDrive.
Example: Resizing a Snapdrive-LUN with OnCommand System Manager create huge "busy" snapshots in a Snapmirror-Relationship, that cannot be deleted!

Which type of LUN is that one?
Is this a dynamic disk?
Looks like a kind of comunication issue between the windows machine and the virtual environemtn (i guess this is an RDM lun). Did you already try to restart the SD service?
Have you try to resize the lun direct on storage controller and than use windows disk management und expand the drive after refresh ?
Thanks for the hin but i've never heard of one special disk geometry from SnapDrive.
But my lun initial not created with snapdrive, that could be the rasion i have not seen any issues.
