# ======================================================
# Datastore and LUN Enumerator

# Simon Strutt Nov 2010

#
# ESX v3
# Thieved and adapted from the good work by catman...

# ESX v4
# Thieved and adapted from the good work by notorious_bdg...
# http://communities.vmware.com/thread/171214
#
# Version 3 - Nov 2010
# - Enumerate for a VC (rather than just an ESX)
#
# Version 4 - Nov 2010
# - Added handling for ESX v4
#
# TO DO...
# - Get-DS-LUNs assumes all ESX's connected to a VC are same version, resolve
