Why disk size at server end does not change when I reduce the corresponding LUN size on the storage array?

-

hello,

i have server has been allocated lun storage array through san. size of lun 1.7tb , server sees disk of size.  there single partition have created on disk , size disk space available. can access through drive letter.

now storage array has option change lun size , using reduced lun size 1.7 tb 1.5tb. however, @ server end, after rescanning the disks still see this corresponding disk of size 1.7tb primary partition. may reason behind this?

i tried see what happens if increase lun size , saw @ server end, disk size change , space available shown unpartitioned volume along primary partition. can make partition on new volume or extent volume of primary partition , hence keep single partition on disk.

but things not clear when reduce lun size.....

what think?
