Synology iSCSI Disconnect Issues

[ukjamesh]

Hi all,

I'm in need of some help

Over the last few days I've been trying to get iPXE connect to my Synology iSCSI target with little success. I want to do this so I can boot from SAN ESX in my lab.

So far I've configured the following...

Added DHCP options for undionly.kpxe to boot from tftp.
Embedded a script in undionly.pkxe to load a script from http.
The script contains the following

#!ipxe
sanboot -k iscsi:172.16.10.229::::iqn.test.com || chain http://172.16.10.230/pxelinux.0

Created pxelinux.cfg/default to point at a menu for the ESXi installation via http if sanboot fails.


When I attempt to boot a diskless host(VM in workstation at the moment) I see iPXE load and then the ESX installation starts. Which is all good but I dont get presented with an iSCSI lun to install into...
I've looked at the iSCSI logs on the target I see Login, which is then followed by Close about 15 seconds later...

So at this point I'm not sure if the issue is with iPXE or the target. So I built a freenas iscsi target and I was seeing the same issue.

I've tried to make it was simple as possible by booting onto the ipxe.iso and running the following

dhcp
sanhook iscsi:172.16.10.230::::iqn.test.com

which responds with

Registered SAN device 0x80

but I still see the disconnect on the iSCSI Synology server about 5 - 15 seconds after.

I even tried a Freenas iscsi target and in the logs it gives me this
freenas WARNING: 172.16.10.127 (iqn.initiator.com): no ping reply (NOP-Out) after 5 seconds; dropping connection

Anyone got any ideas? Should what I'm trying to do work?

Thanks

James
