Issues moving a 6 disk XRAID set from a deceased Ultra 6 to an RNDP6350
Good day to all,
First a little background...
I have a ReadyNAS Ultra 6 that has been my backup platform to my production NAS (at home) for about 2 years. Recently it crapped out and I determined that it was a hardware issue that could only be repaired by replacing a damaged hard disk back plane board. Since these are almost impossible to source out I decided to get obtain a disk-less RNDP6350 to replace it and, hopefully, recover the 20TB of data sitting on the disks. I purchased one with a bad PS on the cheap off fleabay and replaced the bad power supply with new one. That PS swap out went swimmingly, other than knocking off a small heat sink that I put back on with some silver thermal paste, so I now have a live box. <<< (Special thanks to Sandshark here for providing some really great input to make this easier). Here's where I'm having some issues...
I'm not sure what I should do next to recover the RAID set or if I even can. I put a single new disk in the box and powered it up. It posts fine but when it comes to the part where the box starts to boot I get the message below:
ERR: could no mount root RAID d
While I'm a newbie with the ReadyNAS I suspect that the box might need the original disks that were in it previously to get past this error. Of course that's not possible and I'm sure what is needed is to restore the box to factory default settings. What I'm not sure of is how I do that without risking losing the 6 disk XRAID set I'm trying to recover. Setting to factory defaults wipes out the config and results in the loss of the raid set as well as the data. Indeed, I'm not even sure this is possible and have no clue what the process should be for such a 'migration', so I'm reaching out to the wonderful people here to see if anyone can offer some guidance from their knowledge and experience.

There is nothing stored in the NAS itself regarding any configuration. All of that is on the drives, so moves with your volume.
You should boot the NAS with a scratch drive and see what OS it's running. If it's 4.2.x, I suspect it is, then you'll need to upgrade to 6.0 using that scratch drive (if I recall your PM correctly and you were running OS6 in the Ultra).

I am thinking the Ultra was converted to OS-6 - is that the case? Do you know if the Pro-6 is running OS-4? Or was it also converted to OS-6?

Thank for your response. I suspect that a factory reset will be necessary to clear the old configuration data and clear the error, and I have disks I can use for a test disk. What I'm concerned about is if I can ultimately install the 6 disk RAID set from the damaged Ultra 6 into the RNDP6350 and regain access to the data on it and, if so, how to do that successfully.

Hey SS, thanks for your help! Yup, the Ultra 6 was running 6.10.10 but its a dead unit so it appears to me that I can't recover the VPD file from it. How do I get the box to boot with a scratch drive? I'm getting the ERR message that I posted earlier when trying to do so

Great advice on the memory. You had told me this a while back so thanks for the reminder. I'll install the additional memory from the Ultra into the 6359 before I do anything else as your recommend! Also, I grabbed a Intel Core 2 Duo E7600 3.06 GHz Dual-Core CPU and remember you telling me that the box would require the latest BIOS upgrade that can be performed on 4.x but the upgrade won't work with OS6. I guess I'll need to identify the current version of OS on the 6350 before I can go forward with any CPU upgrade. The CPU hardware replacement itself looks pretty straight forward. Is there some sort of procedure document floating around that details the CPU upgrade process?
Re: Issues moving a 6 disk XRAID set from a deceased Ultra 6 to an RNDP6350
I have it all now. I just added additional memory to the 6350 and installed the scratch disk. I'll use the information to try and reset the box to factory defaults. Please stand by!
Re: Issues moving a 6 disk XRAID set from a deceased Ultra 6 to an RNDP6350
Opps, after rereading your post Sandshark I realized I should be backing up the VPD file from the target box, not the Ultra, before upgrading to OS6. I've got the machine to boot from the scratch disk by setting to factory defaults and it's available on the network but running TLS 1.0. I actually have run into this before so I had to do some work around stuff to access the RAIDar admin screen. It's alive!!!!

Memory upgrade to 3GB, update of the BIOS, backup of VPD file and upgrade to OS6 on the Pro 6 has completed successfully. Grateful shoutouts go out to Sandshark and StevenB for their great help and providing the information needed to get this upgrade and data recovery done. I've been able to recover ~24TB of backup data with the help of the great people here.

Upgraded processor arrives today. Based on my understanding this will be a simple CPU hardware swap, with no other patches or software required. Am I correct in that assumption?
