Operating Systems Linux Red Hat Partitioning newly added disk to Redhat Post 302585171 by verdepollo on Tuesday 27th of December 2011 08:32:43 PM

Well, Red Hat strongly suggests not to use whole disks as PVs.

Using whole disks increases the risk of an external application overwriting the data under some rare circumstances.

Here's an example of this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=154841

Even though most of those problems have already been patched and fixed in latest RHEL releases, Red Hat still discourages that practice for production/critical systems.

Using partitions of type 8e is the preferred method.
