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
