Yeah frustrating wasting valuable man hours wrestling with this. However, i think i may have just found the issue. When i first set up the iSCSI LUN's, they were unauthenticated with CHAP. Shortly before the update, i added CHAP authentication to them all and reconnected my hosts. After the upgrade, i started having the issues where all the LUN's went 'Reconnecting' and the NAS box was hanging. I read somewhere that another user had an issue where if any unathenticated hosts tried to connect to a LUN, it would crash the iSCSI service on the NAS. I have since turned off CHAP authentication on the LUNs to test and so far, everything has stayed connected! Not ideal, but for now it is stable and controlled by firewall rules to access.
Let's hope it stays that way else i agree with you...... i'm grabbing a bat as wasted many hours.

So the problems are all resolved by disabling CHAP?
If not I can have a look at your system if you like.
If you're still having issues you could start by downloading the logs using RAIDar then sending them in (see the Sending Logs link in my sig)

No I can't sent you any logs, because I dit an Factory Reset again. I have not time and no drive to find out by my self how to disable CHAP and read hours ans hours form some maybe-sorted-Problems.
I would like to know how to disable Netgear-Firmware-Updates in the future?

It's getting in a hateful regularity to fix Problems after firmware-updates from NETGEAR. How can I diable CHAP on the ReadyNAS? How can I disable automatic-firmware-updates?
- gregwhite886Jun 07, 2017Tutor
On my NAS's, firmware updates won't automatically install and have to be started manually so can't connect on that. As for CHAP, under my individual ISCSI groups, there is an option to untick, Require authenticators to initiate using CHAP. Do that for each group and reconnect your ISCSI drives.
That worked for me.
