Using the vSphere Client, check the Storage Adaptors and Storage, you will notice that a storage device will be known to ESX as a Fibre Channel Device, and if you select the properties of the datastore, if you see the following partitions on a Fibre Channel device, with a low LUN number of 0 or 1, it's highly likely,. that ESX has been booted from SAN, rather than a RAID array.

From our environment some of them booted off from local disk and some of them from san lun, but  I'm not sure how to find it was booted from san or local disk. Is there a way we can find?

if they are SAN booted, you will have dedicated a single LUN for the installation.

the output from df and vdf will give you a clue, and also fdisk, and grub loader
