Thanks Jim,

Is there an advantage of having the disk partitioned instead of having a raw disk or would there be any reason partition your disk if you are using the entire disk to add to LVM?

If you get better performance with raw disk and no benefit of partitioning the disk it seems like more work for a worse solution to bother partitioning them (i know not much work but there are quite a few disks per server).

VGSCAN(8)						      System Manager's Manual							 VGSCAN(8)

NAME
vgscan - scan all disks for volume groups and rebuild caches SYNOPSIS
vgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes] [-P|--partial] [-v|--verbose] DESCRIPTION
vgscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of other disk devices in the system looking for LVM physical volumes and volume groups. Define a filter in lvm.conf(5) to restrict the scan to avoid a CD ROM, for example. In LVM2, vgscans take place automatically; but you might still need to run one explicitly after changing hardware. OPTIONS
See lvm(8) for common options. --mknodes Also checks the LVM special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused ones. --cache Scan devices for LVM physical volumes and volume groups and instruct the lvmetad daemon to update its cached state accordingly.
