Re: Question about san boot - iscsi initiator

Hello again Mahboob,

You can do this fairly easily.  The way I've set the initiator IQN was
through the use of a script.  If you drop to the gPXE command line and
type "config" to enter the configuration menu, you'll see all the
variables listed there, and one of them should be "initiator-iqn."  By
default, the initiator IQN is configured to what you're seeing there,
as "iqn.2000-09.org.etherboot:UNKNOWN"

You can set it to anything you like by specifying the value for it
from the command line or through a script.  Using
"desktop.rulerof.com" as an example, you could do:

> set initiator-iqn iqn.2011-02.com.rulerof.desktop:iscsiboot


Alternatively, the doc suggests that you can also set the initiator
IQN using DHCP option 203 (defined here:
http://etherboot.org/api/dhcp_8h-source.html#l00399).  I don't know if
I've ever done this, but it should work.  Not sure off the top of my
head what you'd need to do to get it set up, though I suspect it's
easier for ISC DHCP than MS DHCP ;-)


The script-based method is more straightforward, but if you're
currently booting your client using the DHCP root-path option,
converting over to a scripted setup can be a bit of a chore.

Best regards,
Andrew Bobulsky
