There are a lot of SCSI disks as far as I understand ( 68), but they are not mulitpath capable

Here are the commands I am issuing to get the installer:
wget http://cdimage.ubuntu.com/ubuntu-server/daily-live/current/groovy-live-server-ppc64el.iso
mkdir iso
mount -o loop -t iso9660 groovy-live-server-ppc64el.iso iso
kexec -l ./iso/casper/vmlinux --initrd=./iso/casper/initrd.gz --append="ip=xx::xx.xx.xxx.x:255.255.255.0:ltc-boston113:enP1p9s0f0:none:x.x.x.x rl=htt:/xx.xxx.xx.xx/ubuntu-server/daily-live/current/groovy-live-server-ppc64el.iso --- quiet "
kexec -e
The system is going down NOW!
