+=== Recover lost SAN VMFS partition (ESX4) ===
+Recovering SAN LUN's that can be seen by the ESX, but for which the VMFS isn't visible can generally be resolved by re-adding the storage...
+# In the Configuration > Hardware > Storage view of an ESX, select '''Add Storage...'''
+# The ESX should find the LUN, and correctly display its VMFS name in the ''VMFS Label'' column
+# Select the LUN and click Next, then try each of the following options in order to re-add the VMFS (if neither of these options are available see further procedure below)
+## Keep the existing signature
+## Assign a new signature
+# Refresh the storage on the other ESX's that can see the LUN.
+If you're unable to re-add the VMFS without formatting the disk, but the VMFS is visible to at least one ESX, then perform the following to get the VMFS added to ESX's that don't have it
+# Get the UUID of the volume (the ''Can mount'' flag needs to be ''Yes'')
+#* <code> esxcfg-volume -l </code>
+# Force the ESX to mount the volume
+#* EG <code> esxcfg-volume -M 4d2b6ba3-123ebca8-4f9b-18a905c1234a </code>
+# Refresh the storage view in vCentre
+# If the VMFS is a scratch disk, restart the ESX
