[ipxe-devel] question on iSCSI boots

Hi folks

   Other question has to do with iSCSI boots.  I have a number of 
operational iSCSI servers.  Targets are alive and visible.  I can attach 
to them.

   What I can't do is seem to convince ipxe to attach to them.  sanhook 
and sanboot fail.  I get some log indications that things were starting 
to go when it bailed.

   From my logs (using scst and iscsi-scst)

***ERROR***: Connection with initiator iqn.2010-04.org.ipxe
:36168950-879f-4d56-8263-6bf5b4c63c11 unexpectedly closed!

Not sure what the error is about, other than the initiator closing.

Any hints as to how/where to debug?  I'd really like to set up the iso 
booting at some point.

Thanks!

Joe
