[RN2120v2] No web management access after channel 4 failure
My RN2120v2 is running ReadyNAS OS 6.7.4 and I have 4 Samsung 1TB SSD 850 EVOs installed. I pulled the disks after a powerdown and clear them (low level format). Now it does not matter which SSD I pl...

It turns out that I had to do the following to get this system out from Tech Support Mode and get the Web Management interface (frontview) to come back up.
1) USB Recovery Mode - boot and let the OS image reload from USB
2) Boot Menu - OS Reinstall to refresh the OS on the Disk.
3) Boot Menu to Normal mode - wait till the NAS is up and pull the ethernet cable to restart the LAN interface
4) Web Interface was finally available - all was good!
Not sre why the sequence - but this worked and I found a few others that posted similar results!
Thanks for all your help!

Actually I am good with all the disks now, turns out that channel 4 had some dust in the SATA connector so by cleaning that out, everything worked. The issue seems to be that I used Boot Menu Mode to go into Tech Support mode (Telnet) and once in there I used "reboot" to restart the NAS. I've gone back into Tech Support mode and the NAS does show up in RAIDar at that point. I've tried going to the Boot Menu again and forced Normal Boot and also OS Reinstall, neither will bring the NAS web management interface back online. The NAS is fine, just no web management. Thoughts? Oh and THANKS for getting back with me... Yes all the drives are accessable via a PC SATA connection.

The "brute force" way is to back up the data, do a factory reset, rebuild the NAS, and then restore the data. Since you are using SSDs, that might turn out to be the fastest method.
Paid support is of course always an option.

I already did a "Factory Reset", the problem is that the web management interface will not come up. I'ts not available. The NAS is not even litening on that port for web requests. I can boot into Tech Support mode and the NAS shows up in RAIDar as in "tech support" mode with a Debug Code. It seems that once you are in that mode, you need to have "tech support" do something to unlock the system again. I have support contracts so I'll just give them a call I guess. Thanks! I'll post any solution they provide.

Powering off the system (e.g. by unplugging the power) and turning it on again would return it to normal mode. Alternatively support can issue the reboot command to reboot a system.
Tech support mode is a low-level diagnostic mode used by support to troubleshoot problems that cannot be dealt with (or are best not dealt with) whilst the system is running normally. The RAID has to be started manually and the root volume and data volume(s) mounted manually.
In normal mode you may still be able to download the logs using RAIDar if the web admin interface doesn't come up.- techiesjcJun 17, 2017Aspirant
