r720xd
Normal PXE boot. Modify /etc/dhcp/dhcpd.conf to identify the first port. You'll need to get that
from racadm dump.
First stick is CentOS min:
dd if=CentOS-7-x86_64-Minimal-1708.iso of=/dev/sdb
sync
# remove
Next stick is a kickstarter disk:
# Create a KS disk
fdisk /dev/sdc <<'EOF'

fatlabel /dev/sdb1 OEMDRV
mkfs.vfat /dev/sdb1
mount /dev/sdb1 /mnt
grep -v url centos7-ks.cfg > /mnt/ks.cfg
umount /mnt
sync
The centos7-ks.cfg should not refer to a remote url.
Put two SSDs in the 2.5 inch slots in the back of the r720xd without any extra disks. The
ks.cfg will create a raid config.
Press <F11> to select BIOS boot. Then select C: drive which will popup a choice for the
back or front USB stick. Choose the one with CentOS.
Normally OEMDRV will get picked up automatically except for this bug so you need to follow the instructions
Once the install boot screen is up, select Install (first line) and press <tab> which will
allow you to enter at the end of the line:
quiet inst.ks=hd:LABEL=OEMDRV:/ks.cfg
em1 is shared with the idrac so we use em2 for the dhcpd net. You'll need to edit /etc/sysconfig/network-scripts/ifcfg-em2
with something like:

BOOTPROTO="dhcp"
DEFROUTE="yes"
ONBOOT="yes"In Linux, memory controller 1 (MC1) is Processor 2 (CPU_SrcID#1)
