if you have a SAN that supports logical volumes that have snapshot and grow and such, I'm not sure why you'd bother with LVM on top of that, it would just further obfuscate things.
Makes life easier for me when using MPIO, auto detection of the volume no matter what path it shows up with. And I can slap an easily readable "label" on the volume so I know what it is.
Sample log from one of my oracle snapshot procedures: http://portal.aphroland.org/~aphro/san/oracle-restore-prod-oracle-1a_2008031...
And it allows me to better control growth with thin provisioning, some apps are not thin provisioning friendly so I restrict them with LVM, knowing that I can easily do an online resize at any time without touching the array.
