Multiple iSCSI targets during kickstart for root multipath

[GProcunier at symcor.com]

Hello,

I was curious if you can define multiple iscsi targets / iqn's in a 
kickstart?

I have two iSCSI target portals with clustered access to a hosts root disk 
for HA and would like to have the installer see both iqn's and 
setup/install on the multipath abstraction.

                      ---- Portal A ----
                     |                  |
[bare metal client] -                    - Shard Storage (SAN)   
                     |                  |
                      ---- Portal B ----

Portal A
(10.10.10.10:3260,iqn.1970-01.com.example:netclient.rootdisk)

Portal B
(10.10.20.20:3260,iqn.1970-01.com.example:netclient.rootdisk)


Can I just go:

iscsiname iqn.1970-01.com.example.portal-a:netclient.rootdisk
iscsi --ipaddr=10.10.10.10 --port=3260
iscsiname iqn.1970-01.com.example.portal-b:netclient.rootdisk
iscsi --ipaddr=10.10.20.20 --port=3260

Then boot the machine with the mpath option to detect the multi iscsi path 
for installation ?

I did some experimentation and determined that you can pass dracut 
multiple netroot's so the disks are visible when the kernel loads up.

Eg.

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu

        kernel /vmlinuz-2.6.32-131.0.15.el6.x86_64 ro 
root=/dev/mapper/vg00-root_fs 
netroot=iscsi:neclient-root:iscsipw at 10.10.10.10::3260::iqn.1970-01.lab.example.portal-a:netclient-0.root
