1.Is it a VMFS3 or VMFS5 datastore?
2. Do you have an option which says "Expandable" as YES when you try to resize the LUN?

if you click the properties of the datastore, do you get an Increase option?

otherwise

two options

1. backup vms, delete datastore, recreate datastore, restore vms
2. manually extend datastore at command line
