What error do you get? Provide error messages or relevant log errors.
What versions of ESXi, vCenter, GuestOS, GuestOS version, VM hardware version. We can't even guess based on the lack of details. Are you sure you have 2TB free on the datastore? Make sure you don’t have snapshots, you can’t extend a vmdk with a snap.
For example, if you're running ESXi 5.0 the vmdk size limit is 2TB minus 512k. Older versions have a 62TB limit. So details matter.

Hi Team,
Unable to extend VM D drive which is showing 1.53 TB, want to extend with some more space could not able to do so.
Enter disk capacity which is larger than its original capacity - tried with 2 TB also no luck.
