# Parted HowTo (you can easily turn this in to automated script.)
# This HowTo describes how to prepare HP server with SAS drives to use LVM.
# Asume that disk 1 has Proxmox (no mirroring) and that disk 2 will hold first VM storage.
# cciss - HP Smart Array
# Compaq Command Interface for SCSI-3 Support

# Use this command to install Parted & LVM
apt-get install parted lvm2 -y

# Use these commands to list available storage devices
# lsblk
# parted -l
# pvs
# vgs
# lvs
# cat /proc/partitions
# lsscsi

# Incase you need to remove the first partition on disk2...
# parted /dev/cciss/c0d1 rm 1
parted -s /dev/cciss/c0d1 mklabel gpt
parted -s /dev/cciss/c0d1 unit mib mkpart primary 1 100%

# Incase you need to remove the first physical volume on disk2...

Wiki's is 2 general.
This is so specific that it can actually be converted to script by just changing the (RAID controller- and) drive names.
Parted is also a light year ahead of other disk managers because it can be scripted easily.
