Unable to connect to Admin Page on RN2120 after firmware 6.7.5 upgrade
Hello all, I have a NetGear ReadyNAS 2120 which has never missed a beat until last week when I upgraded the firmware to 6.7.5 (latest). The unit rebooted as normal however after I was unable ...
The NAS has vanished off my network.
IP no longers responding, RAIDar shows no NetGear NAS, its like the unit isn't even there.
Then powering down, removing the drives (labeling by slot) and powering up is a reasonable next step. If the chassis is working, you should get a "no disks" status from RAIDar.
You could also run a memory test from the boot menu (see page 13 here: http://www.downloads.netgear.com/files/GDC/RN2120/ReadyNAS_OS_6_Rackmount_HW_UM_10Dec2014.pdf )
While the disks are out, you could also connect them to a windows PC (usb is ok) and run the vendor diags (seatools for seagate, lifeguard for western digital).
I powered the unit off, ejected all the drives then powered the unit back on and it looks to be working.
RAIDar first showed a message of 'System starting up ..' then it changed to 'No disks detected'. The unit now has a IP from my DHCP pool .15 however I'm unable to assess the Admin Page, I suspect this is normal.
I powered the unit off again, inserted the drives then powered the unit back on and again there is no sight of the NAS on the network.

Yes. The OS is on the disks, and the boot loader has no admin page.

Ok. So you'll ruled out the NIC(s)s and most of the system board. I'm think that most likely the problem one of the disks, but there are still some chassis failure modes that could be happening. For instance, a failing PSU or a memory issue.
I'd test the disks next (in a PC as noted above) and run a memory test on the NAS chassis in parallel.
If you have a spare disk (not in the array) you could also try a factory install using just the space - that also is a way to test the chassis. Once built, you can try that disk in each slot, to test all the SATA connections. You'd do that by powering down, moving the drive, powering up, ....
