Recover VMFS datastore to ESXi 5.1 host

I have a single ESXi host connected to a Nexsan 18 SAN via ISCSI and recently had to reboot the ESXi host.  Upon the reboot, one of my volumes will not show up as a datastore.  The LUN is still showing up as a device, but when I go to add it, it does not give me a resignature option (as noted in some posts/kbs) and I only have the option to format.  These were created fresh as vmfs-5 volumes

I've looked and it may be that the partition table has been lost and that I should be using the partedUtil command to create a new one?  If I understand correctly, this will not format the volume?

I ran this:

partedUtil get /vmfs/devices/disks/naa.6000402002d84a6b7b8fe6a100000000

and got:

I also ran 'fdisk -l' for this info:

Disk /dev/disks/naa.6000402002d84a6b7bd658df00000000: 1953126400 sectors, 1862M
