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_20080319_230901.log 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. nate
