There is no way to take the easy route and just use different subnets is there? I am just asking because I think using ifaces could be too much fun :) See below. > Although I have configures a custom iface using iscsiadm I cannot get > my system to use it.

Centos does not have support for this in its iscsi boot support. It does not support booting off of ifaces, so you have to hack it in. In the initramfs you would want to remove iscsistart and thrown in iscsiadm and iscsid and the iface files and node files. I think you might have to recompile iscsid and iscsiadm statically or also thrown in the libs those programs use. You also want the node and iface files that get created when you ran the iscsiadm discovery command or node binding command to get: > Iface: iface1 > Target: iqn.1992-08.com.netapp:sn.15333 > Portal: 192.168.1.12:3260,2000 So you could just throw in everything in /var/lib/iscsi. In the initramfs (is the script called init in centos 5.6) you would want to do // start network // start iscsid iscsid // run iscsiadm to login using iface iscsiadm -m node -I iface1 -T iqn.1992-08.com.netapp:sn.15333 -p 192.168.1.12:3260,2000 -l // kill iscsid because when you pivot to the real root iscsid will be restarted by the init scripts. killall iscsid -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
