Q: undionly.kpxe and sanhook to iSCSI target

[Andromeda_x]

Hello,

I am attempting to gain access to iSCSI target and no success as of this moment and I am confused why it does not "attach" my target.

System configuration:
1. iSCSI target located on Debian 7 machine (moon.coguar.com 192.168.64) where I can access/attach/mount iSCSI locally
(what confirms that it works properly)
(iSCSI target also added in initiators.allow file for test computer)
2. test computer (192.168.0.30) boots from network (DHCP serves undionly.kext)

iSCSI configuration (Debian 7)

Code:

/etc/iet/iet.conf
....
....
Target iqn.2016-12.com.coguar.moon:storage.lun0
        IncomingUser netadmin NetSecret
        OutgoingUser netadmin NetSecret
        Lun 0 Path=/a/lun.img,Type=fileio
        Alias LUN0
        #MaxConnections 6

/etc/iet/initiators.allow
.....
.....
iqn.2016-12.com.coguar.moon:storage.lun0 192.168.0.30

I boot test computer and get into IPXE then I issue following command

Code:

iPXE> login
iPXE> sanhook iscsi:192.168.0.64::::iqn.2016-12.com.coguar.moon:storage.lun0
Could not open SAN device: No such device (http://ipxe.org/2c0d603d)
iPXE> sanhook iscsi:192.168.0.64:::0:iqn.2016-12.com.coguar.moon:storage.lun0
Could not open SAN device: No such device (http://ipxe.org/2c0d603d)

Snooping on the network traffic by tcpdump shows that computers talk to each other and I am not sure how to troubleshoot the communication

I try to configure a system to net boot diskless test computer through DHCP into iPXE and then ipxe script kicks in to "sanhook" iSCSI target as 0x80 drive and after that to proceede with Windows installation.

Currently script is disabled and I try to find out how "sanhook" works and I am puzzled why I get the message "Can not open SAN device: No such device (http://ipxe.org/2c0d603b)

Code:

#!ipxe

login
sanhook iscsi:192.168.0.64::::iqn.2016-12.com.coguar.moon:storage.lun3

cpuid --ext 29 && set arch amd64 || set arch x86
kernel wimboot
initrd ${arch}/media/Boot/BCD          BCD
initrd ${arch}/media/Boot/boot.sdi     boot.sdi
initrd ${arch}/media/sources/boot.wim  boot.wim
boot

Where is my mistake? What am I doing wrong?
