While adding a new disk to an ESX5.5. box it could not finish the partitioning stage and did not add to the Datastores.
Apparently ESX does succeed to clean up the Disk from the GUI.
NOTE: This procedure will destroy all data on the disk
# esxcfg-scsidevs -l
this lists the disk devices, the device file will be /dev/disks/<NAME>
output looks like:
t10.ATA_____ST3320620AS_________________________________________6QF1PZXB

# partedUtil get /dev/disks/t10.ATA_…
this shows the partitions on the device output looks like:

2 314080 325137344 453 0
this disk has 2 partitions, numbers 1 and 2
# partedUtil delete /dev/disks/t10.ATA_… 2
deletes partition 2
# partedUtil delete /dev/disks/t10.ATA_… 1
deletes partition 1
