Thanks for the reply. This is how i previously did it.
First , i made sure that the disk is written with a partition table for that did all the steps by going to fdisk /dev/sdc and then created partition and then created my primary(as 1) and then configured it to be LVM(whole additional storage disk).
second stage,pvcreate /dev/sdc1 and then vgcreate vg0 /dev/sdc1
third -lvcreate -L 4T -n lvol0 vg0.{at this stage it is not allowing me to create how much i need to do, later when checked i came to know that it's of 2TB
Like I said, we need the EXACT error msgs; saying it didn't work/not allowing doesn't help us.
In any case, seeing as you have a RHEL system there, you should search their Knowledgebase and/or phone their support.
