ESXi - Cannot use all available space on a LUN.

Hopefully i'm missing something, but here goes:

I have a brand new install of ESXi. There are 2 RAID Arrays, one 74Gb array with the OS installed and one 3.4Tb array which i want to convert into a datastore to house VM's. My problem is, when i go to add the 3.4Tb datastore it will only "see" 1.4Tb of space (if i look at the storage adapter, it sees the LUN as a 3.4Tb blank drive).

How do I make the whole 3.4Tb usable?

TIA...

Thanks, that makes sense. however, the fact that it will not allow me to create anything at all larger than 1.4Tb and the fact that once i do create a 1.4Tb drive and then it reports no more free space on the LUN still confuses me....

Probably need to delete the lun then recreate via the array controller with lun sizing set to <2 TB for each lun created.

Not to beat a dead horse, but, does anyone have any insight as to why it would not let me create a 2Tb disk on the LUN as it currently stands? (i'm somewhat hesitant to blow away the 3.4Tb array and create two smaller ones in case i end up getting the same issue again)..
