any advantage in LVM if we use a fidisk partion to pvcreate other tha using direct disk. some bosy says it is good to avoid using 1st cylender , so creating partion starting from 1st cylender and using this partion for creating a pvcreate to create VG.

Yes. Partitioning is recommended and may also soon be recommended.

Reason is an increasing number of utilities will complain or report a disk as having no partition table. A nuisance really but RH may actually have a more valid reason why.

I think Oracle and RHEL now recommends paritioning as well.

In our case, we adopted partitioning for EVERYTHING - disks used under LVM and ORACLE ASM are paritioned wholly -- meaning the p1 partition is the only partition on the disk and occupys all of capacity.

The only exception is VxVM managed disks.
