Thanks for the logs
2013-06-22T17:21:21.026Z: No vmfs datastores found for naa.600188b039df110019587854044a724c
What if you try recreating the partition table on the device and check?
Use fdisk if vmfs3
use partedutil if vmfs5
Please open a support ticket with VMware if you are unfamiliar with the commands as directly modifying the vmfs filesystem can have unrecoverable consequences if not done correctly
