lvm on whole disk for online resizing supported ?

Hello all,

We use Redhat 6.5 VMs on Vmare Vsphere.
I put all my lvm on a whole disk ( pvcreate /dev/sdb for example)

With this kind of setup, i can resize my VMDK and the PV => VG => LV online, no need to add partition or reboot.

Is this setup supported by Redhat ? (LVM whole disk configuration)
Is a KB that prove that ?

Thank you
