UTM 9.3 running on hyper-v 2012 R2 inaccessible after iscsi failure.

Hi,

I'm running a UTM 9.3 home edition to test some features.   I've installed the appliance in high-availability on our hyper-v 2012 r2 cluster.      The storage is on a iscsi-lun.   

Due to a backup issue, the iscsi channel timed-out causing all vm's to hang.

After resolving the issue all vm's are running fine again except the utm.    It's not responding to any ping request anymore and I couldn't login by using cli also with my username and password.

I've followed the password recovery procedure and I can get access through cli now.

When checking the ethernet interfaces, both interfaces (internal and external) have the status disabled.      When trying to change the status and saving the changes nothing happens and the intefaces stay disabled.    

I also tried to set the mac addresses as static on the hyper-v side but the problem remains.

Anyone who has a idea what's could be wrong ?     I can start over from scratch as this is just a test-environment but it would be great to know how to solve this just for learning purposes.

Thanks.
