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.
I am not sure if there is a way for me to see the firmware revision anywhere from the boot menu on my broken device. If my notes are up to date, then it is running RAIDiator 4.2.28
I think the fact that I have the same issue with both power supplies rules that out as the issue.
I'll take a look at the USB Boot Recovery tool you suggest for 4.2. Thanks for that tip! It looks promising.
I am also considering recovering the data first directly from the disks which looks like it may be possible with something like R-Studio or Reclaime. I get nervous messing with the Readynas software in case it decides to reinitialise the disks or something. I would love to hear of anyone managing to recover XRaid data which includes cifs/afs and iSCSI partitions.
I've ordered a VGA Header now as well which seems like a useful thing to have. These are sure hard to find on amazon, but I managed to get this link from the artical titles "VGA Header for my Pro 6 RNDP6000". Now just wonderind it a USB keyboard will work.
I suggest testing the disks with vendor tools in a Windows PC (Lifeguard for Western Digital, Seatools for Seagate).
Normally the system will boot from disk 1, so test that one first.
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.
