I am creating a VD in the MD300i, this presents itself in V Center, it is 1.36B,however when I try to connect an ESXI host it, it cannot use more than 256GB? I changed the block size to 8MB but it makes no difference. I have done this before and cannot seem to work out why it will not work now. I recently upgraded to ESXI 4.1 and Vspeher 4.1. I have an existing VMFS that I use for VM storage.
