no iSCSI target for win7 install (several examples - none work)

[dsantini]

Hello everybody, I am unable to install win7 to iscsi target, I manage to get to windows setup but
no drive is detected. I tried several approaches (on real machine and in virtualbox).

Notes:

• I am using isc-dhcp-server (ipxe config is on the bottom of this post), tftpd-hpa, apache2, ietd
• iscsi target is accessible and works fine (connected to it through normal w7 machine)
• tried all examples with both virtualbox and real machine
  

I used info found on these links to get where I am now with regards to ipxe:

http://ipxe.org/howto/winpe
FAQ on this forum
http://etherboot.org/wiki/sanboot/win2k8_iscsi_install

Any help/suggestion would be appreciated ..

Cheers,
Dorijan

1. SAN only with iscsi target attached - this would be ideal, but it doesn't work for me

Code:

#!ipxe
dhcp
set boot-url http://diskless.voyager.fast

set base-iqn iqn.2013-01.fast.voyager.kira:sedmica
set base-iscsi iscsi:192.168.200.128::::${base-iqn}

# Set initiator-iqn to either hostname or mac
isset ${hostname} && set initiator-iqn ${base-iqn}:${hostname} || set initiator-iqn ${base-iqn}:${mac}

set keep-san 1
set root-path ${base-iscsi}

sanhook --drive 0x80 ${root-path} || echo sanhook failed for ${root-path}

#Start Windows 7 installer DVD
sanboot --no-describe --drive 0x81 ${boot-url}/w7/w7.iso

Screenshot 1 - ipxe happily boots with iscsi target attached and all seems fine


Screenshot 2 - windows boot cd dies with error


2. SAN with winpe - sanhook command, I guess it should work, I manage to get to setup but no drive offered for installation

Code:

#!ipxe
dhcp

set boot-url http://diskless.voyager.fast

set base-iqn iqn.2013-01.fast.voyager.kira:sedmica
set base-iscsi iscsi:192.168.200.128::::${base-iqn}

# Set initiator-iqn to either hostname or mac
isset ${hostname} && set initiator-iqn ${base-iqn}:${hostname} || set initiator-iqn ${base-iqn}:${mac}

set keep-san 1
set root-path ${base-iscsi}

sanhook --drive 0x80 ${root-path} || echo sanhook failed for ${root-path}
cpuid --ext 29 && set arch amd64 || set arch x86
echo found ${arch}
kernel ${boot-url}/winpe/wimboot
initrd ${boot-url}/winpe/${arch}/ISO/bootmgr       bootmgr
initrd ${boot-url}/winpe/${arch}/ISO/boot/bcd      BCD
initrd ${boot-url}/winpe/${arch}/ISO/boot/boot.sdi boot.sdi
initrd ${boot-url}/winpe/${arch}/winpe.wim         boot.wim
sleep 3
boot

Screenshot 3 - ipxe happily boots winpe


Screenshot 4 - winpe boot completed and pinging server with iscsi target

screenshot 5 - starting w7 setup

Screenshot 6 - no drive offered for installation


Screenshot 7 - got to console with SHIFT-F10 in w7 setup to confirm network works


3. SAN with winpe - sanboot command, same output as in example 2. (except ipxe part)
("patched" iscsi target on server with script "#!/bin/bash printf "\xCD\x18" | dd of=$1 conv=notrunc" as suggested in FAQ)

Code:

#!ipxe
dhcp

set boot-url http://diskless.voyager.fast

set base-iqn iqn.2013-01.fast.voyager.kira:sedmica
set base-iscsi iscsi:192.168.200.128::::${base-iqn}

# Set initiator-iqn to either hostname or mac
isset ${hostname} && set initiator-iqn ${base-iqn}:${hostname} || set initiator-iqn ${base-iqn}:${mac}

set keep-san 1
set root-path ${base-iscsi}

sanboot --drive 0x80 --keep ${root-path} || echo sanboot failed for ${root-path}
cpuid --ext 29 && set arch amd64 || set arch x86
echo found ${arch}
kernel ${boot-url}/winpe/wimboot
initrd ${boot-url}/winpe/${arch}/ISO/bootmgr       bootmgr
initrd ${boot-url}/winpe/${arch}/ISO/boot/bcd      BCD
initrd ${boot-url}/winpe/${arch}/ISO/boot/boot.sdi boot.sdi
initrd ${boot-url}/winpe/${arch}/winpe.wim         boot.wim
sleep 3
boot

Screenshot 8 - ipxe happily boots winpe

After that same thing happens as in example 2.

Any ideas?
