QNAP - iSCSI Lun in error cannot mount to Windows

Hi all

I hope someone can help as I'm waiting on QNAP support but no reply yet.

We have a QNAP with iSCSI connection hosting some VM for hyper V. The QNAP lost power when a cleaner pulled the plug and when coming back on line the iSCSI can connect in Windows but no drive is shown. The QNAP shows the LUN in error as shown here .

I've tried to follow this article using Winscp but the LUn never comes enabled.

The iscsi_trgt.conf file output is here and as you can see below.

This is also the screenshot of .@iscsi.img file
I've tried numerous entries on the iscsi_trgt.conf file but nothing seems to work.

Can anyone help as all I need to do it get the VM's hard drives off as I can easily recreate them.
