IPXE :: sanhook does not work properly

[Andromeda_x]

Hello,

I observe a weird situation and looking for help in resolution of the problem.

NOTE: test computer is VM in VMware Workstation 14

* DHCP server is setup and forwards to load iPXE
* iPXE boots and picks up boot.ipxe script
* wimboot initiates
* picks up winshl.ini
* starts install.bat file
** net use \\server\share
** \\server\share\win10\setup [win7,win81,...]
** windows setup starts ok

Now, I want to make installation on san iqn disk.

* Ubuntu 16.04 installed
* iscsi configured with a target for local and remote access
* the target is mounted locally for verification
* in boot.ipxe script added
** set username some_name
** set password some_password
** sanhook iscsi:xxx.xxx.xxx.xxx::::iqn.2019-96.com.domain:storage.lun0
* virtual machine reset
* ....
* iPXE started
* sanhooks attaches iqn as 0x80
* winpe loaded and started
* it takes a while to see 'terminal window' with winpeinit
* response is slow
** net use \\server\share gives an error

Now my question: what did I do wrong?

The setup works fine util I try to attach sanhook in boot.ipxe.... and iPXE reports that sanhook attaches the network san iqn drive successfully.

Then something is not right -- system acts quite slow and it seems like winpe looses network connection (not sure how to troubleshoot this situation).

Does anybody came across this issue? How was it resolved?

Thank you,
Andromeda_x
