add new drive

this step assumes a new drive was added, whether physical for a physical sys, or virtual for a virtual sys. if adding to a system using LVM, set the partition type to 8e (LVM), see "LVM Quick Reference" for adding to the LVM Disk Group for use with LVM partitions

# fdisk /dev/sdb

Note: if the new drive was added to a 'live' system, and it's not showing under 'fdisk -l', rescan with (may need to do this with more than host0, i.e. host0, host1, etc.);

# echo "- - -" > /sys/class/scsi_host/host0/scan

drives greater than 2Tb

MBR (<=2.2Tb/32bit):
# fdisk /dev/sda
GPT (<=2.2Zb/64bit):
# gdisk /dev/sda

using kickstart on systems that have drives greater than 2.2Tb (tested on ent 6, probably not needed on ent 7)
add the following to the ks.cfg profile that was generated for the system being kicked

%pre
parted -s /dev/sda mklabel gpt
%end
