Upgrade and Expand vSphere5 VMFS partition > 2TB

Quick steps to expand a 2TB VMFS3 datastore to >2TB with vSphere5

VMFS3 datastore, ~2TB on a 3.6TB LUN

Click “Upgrade to VMFS5”

Note that the next window will look much different if <5.x hosts are connected.

Note the completed task.

To expand the datastore, right-click and select properties.

Click Increase to launch a wizard, which I’ll skip for today – it’s the same as earlier versions.
After the GUI you’ll see the new size listed.

Ta Da!!
