I have multiple hosts where we setup a 3GB volume on the SAN to install ESXi 4.1, which used up about 1GB for the install and then the rest was used for a vmfs for scratch.
After the upgrade to ESXi 5 it didn't mount that scratch vmfs.When trying to reformat it, I get an error:
Either the selected disk already has a VMFS datastore or the host cannot perform a partition table conversion. Select another disk.
fdisk from the cli shows:

So p2 is the 2.12GB vmfs. Is there anyway to get it mounted again? "esxcli storage vmfs snapshot list" does not list it as a snapshot.
