ReadyNAS Pro RNDP6000 hangs on "ReadyNAS" prompt.
I have a ReadyNAS Pro RNDP6000 that was working just fine. I was having issues getting to iSCSI and so I rebooted it through the web intefrace. Since going down, it has never been able to restart....
The ability to boot with the drives removed went a long way toward saying it was not the power supply or any other hardware issue. While the NAS will say "ReadyNAS" with just 5V good from the supply, there are lots of other things that can keep it from booting. But yours seems to be a software issue. You could just try a USB recovery, or you can put a spare drive in the unit and see if it creates a useable volume. If it does, then the flash memory is also fine.
Unfortunatly, a booting OS4.2.x system shows little on the monitor and does not end with a prompt where you can log into the console. You can install the VGA cable to see if it's a BIOS problem, but I don't think it is.
If booting with a spare drive creates a useable system, you could try booting with each combination of just 5 drives in case one is pulling down everything. Unfotuntely, the Pro6 does not have a read-only boot mode, which is best to use in this situation until you find the right combination of drives that will work.

Thanks StephenB - Seatools reports all drives pass.
Good to know. If the array is still in sync, then RAID recovery ought to work with no data loss. Getting the data out of the iSCSI LUNS could be tricky though. ReclaiMe supports the BTRFS file system - which is used by the currently shipping NAS. That's why it comes up here fairly frequently. R-Studio doesn't support that file system, but is less expensive than ReclaiMe. In addition to the software, you'd also need a way to connect all 6 disks to a PC, and storage to offload the data.
Note you can do the USB recovery without disks installed, and then try to do a factory install on a spare disk to confirm that it works.
If the USB recovery doesn't bring the NAS back to life, then you could contact tech support as Marc_V suggests. You should find out if a data recovery contract would be needed for them to help though. https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
There are a couple of other options
- Purchase a used Pro-6 and then migrate your disks. Keep in mind that the Netgear stopped selling the Pro-6 in 2013, so anything you purchase will be at least 6 years old, and likely older.
- You could also purchase a new ReadyNAS system (for instance an RN526) - that can mount the data volume temporarily (read-only) so you could try to off-load the data. There is some more information on that here: https://kb.netgear.com/29957/ReadyNAS-Migrating-disks-from-RAIDiator-4-2-to-ReadyNAS-OS-6-x86. I'm not sure if that mode will let you access the iSCSI LUNs or not - hopefully Marc_V or JohnCM_S will be able to answer that for you. As noted in the article, Netgear Support can also help (for a cost) if that is needed.

I have now removed all disks and inserted a new disk and powered it up. It booted just fine and saw that I had only one disk installed. It then proceeded to do a Factory Reset and sit for 10 minutes. I think it also did a Firmware install. Anyway, after a while, it came up clean and I was able to log in. It looks happy with no errors being logged other than its concern that I have only one disk. I have rebooted it a few times, with no issues. The web interface states "Copyright © 1996-2014 NETGEAR ® | RAIDiator 4.2.31".
I assume at this point, that I can just put my original disks back in with minimal risk? Since it says 4.2.31 though, does that mean I was previously running this 4.2.31 and not the 4.2.28 that I stated above or is it possible it bumped me up to a newer revision, and if it did, does this increase the risk of just trying my original 6 disks again?
My gaming PC has 7 open SATA ports, so I can hook all the disks up if I need to. From what you said though, it sounds like there is no software available to help with a recovery. Did I interpret that correctly?

Likely you were already runing 4.2.31. Though I wouldn't be concerned if you were running 4.2.28. The changes between 4.2.28 and 4.2.31 were just a couple of security patches. The NAS boot loader would upgrade the OS partition on the disks to 4.2.31, but there's very little risk of anything going wrong.

There is software recovery software out there. R-Studio for Windows should work, and would cost about $80 US for the version you need (which supports software RAID and the ext file system). You can download the software first, and see what it finds on your disks prior to purchase. But you do need to purchase before you can offload your data. https://www.r-studio.com/Data_Recovery_Download.shtml
ReclaiMe should also work, but is quite a bit more expensive ($200 US). You can also see what it finds before purchase. ReclaiMe would be needed for a new OS-6 ReadyNAS - they use the BTRFS file system (which R-Studio doesn't support).
I put the 6 disks back in at it booted up without a problem, with everything looking as I would expect.
Thanks for your help!!!
Now for some new hardware so I can abandon this device before its too late.
I was consideing FreeNAS because it runs on standard hardware and it would be very easy to take the disks out of a broken old system and just drop them in a new piece of modern hardware. Although that is a big benefit over my current system (in an end of life state), xraid gives a far superior experience when it comes to adding disks and growing the space. It would be nice if I could stay with xraid. Would anyone happen to know if the new family of Netgear readynas products has a better migration/recovery path when disks can be "moved forward". It sounds like Netgear may even have gone in the opposite direction and made it harder to migrate/recover with the move to BTRFS which sounds even less standard.
