Make the partition with the id of 8e for LVM.
[root@SRV01 ~]# fdisk/dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won’t be recoverable.
The number of cylinders for this disk is set to 2610.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Syncing disks.
Now we do the same for the hard disks /dev/sdc – /dev/sdf
fdisk /dev/sdc
fdisk /dev/sdd
fdisk /dev/sde
fdisk /dev/sdf
Once done use the following command to see the hdd details.
[root@SRV01 ~]# fdisk –l

Let’s create PV’s for LVM.
[root@SRV01 ~]# pvcreate /dev/sdc1 /dev/sdd1 /dev/sde1
Physical volume “/dev/sdc1” successfully created
Physical volume “/dev/sdd1” successfully created
Physical volume “/dev/sde1” successfully created
Physical volume “/dev/sdf1” successfully created
Let’s remove for testing purpose.
[root@SRV01 ~]# pvremove /dev/sdc1 /dev/sdd1 /dev/sde1
Labels on physical volume “/dev/sdc1” successfully wiped
Labels on physical volume “/dev/sdd1” successfully wiped
Labels on physical volume “/dev/sde1” successfully wiped
Labels on physical volume “/dev/sdf1” successfully wiped
