ReadyNAS Ultra 6 Review (RNDU6000) no network activity???

Thank you for the explanation. I asked a college whom has a lot off stuff on his attic for a extra memory bank. So, first that.

I updated the latest bios. The link is not working btw, you need the same link but with https.

Is it possible to get the vpd file of via WinSCP because now I can access via root the NAS?

The VPD is on the internal flash, which is not accessible with a normal boot, even as root.  Thus the need for the special instructions.

These special instructions are a bit tricky and I don`t want to lose my data. I made back-ups for most important things but there is to much to back-up. What I understand is that you have to be quick for to get that file on the USB stick or else you lose everything. So, if you want to OS 6 you always lose your data and start all over again? And than with the VPD file you set everything back?

When you upgrade to OS6, you lose everything, period.  OS6 uses a different drive format than OS4, as well as a larger OS partition.  You also cannot save a configuration file and restore it from OS4.2.x to OS6.  You are completely starting over and restoring your files from backup.

The VPD is just where your model number and serial number are stored, in an encrypted form.  It's not supposed to be touched by the upgrade to OS6.  But some have found that it was corrupted or deleted as a part of the upgrade or a later update of OS6 on a legacy unit.  And if it's missing or corrupt, you can't properly boot the NAS.  So backing it up is a precaution.

Okay, I understand now. From scratch! I have to find temporal back-up than first. And getting the VPD file is simple to do?

How simple backing up the VPD file is depends on your level of experience and comfort with the Linux command line.  Read the instructions in the post StephenB pointed to and make that determination for yourself.

I want to thank you all for the help. I couldn't have done it without that help. I need to think carefully about what I'm going to do next. At the moment I find it tricky to bring this NAS to OS 6. Although I find the process of doing it very interesting and fun. In the meantime I have a new disk in the NAS and it is back as it was. Maybe I'll buy a whole new NAS. One of these times with the specs of this time.

Okay, here I am again. It took some time to get the memmory banks but they are inside now. I have 2GB memmory. What should I do first?

Making sure the backup is complete is the first step.  Since the conversion process can corrupt the VPD (never has for me, and I've converted a lot of units, but there have been reports here), then backing up the VPD is the best next step.  Then, the actual conversion.  The steps that take a significant amount of time are the backup, sync of the OS6 volume, and restoration of files.

Okay, first to get that VPD file. I hope I can get it off the NAS.

Sandshark posted instructions for that here:

 I can not log in via putty?

I have trubbles to get in support tech. The manual is not correct. They say to hold the reset button in and than with the backup button too scroll but that does not work. When I release the reset button I can scroll but any other button I put in nothing happens.

Okay I am in Techsupport and get an IP but can not get in via putty?

"Can't get in" is not much of a description.  Don't connect at all, or the credentials are refused?

In Tech Support mode, you use Telnet, not SSH.  Putty can do that, but if you are used to using SSH, that will be the default.  You also have to use user name root and password infr8ntdebug.  If those don't help, then you need to be more specific in your description of the problem.

I did what is in the manual. Via putty with telnet but no connection.

I tried to boot the NAS again but it is not booting any more. So, I dont know what happend??? Only seeing READY NAS. And RAIDar can not find the NAS either. Even without disks it is not booting.

Sadly, this is sounding more and more like a hardware issue and you just got lucky when it booted a few times.  Are you back to seeing no Ethernet activity?  Try turning it off for an extended period and re-boot.

No network activity indeed. Could it be that the NAS is initializing the disks some how? Or because off the 2 new memory banks?

Did you ever get it to boot past "ReadyNAS" on the display with the new memory?  If not, it could be either the memory itself or something that came loose when you added it.  It's not the drives initializing.  Even though access can be a bit slow, your NAS is still accessible during volume initialization. 

With the new memory banks it was just working fine. Boot a several times and it was accessible. After trying to get in support tech modus it was till working fine. Just when I was to try again and check Putty is via telnet and not SSH, I pushed twice for shutting down. After that is was not booting again. I tried also with the old memory bank but still the same. Not booting, no internet led`s and not accessible. So it is not booting. With disks or without disks. With new memory or old memory.

And the display just says "ReadyNAS"?  Could be flash memory corruption, for which a USB recovery is the solution.  Did you successfully back up the VPD file?  Since USB recovery re-writes the flash where the VPD is located, corruption of it is possible (though it's supposed to be protected).

Yes, only READYNAS and fans full blowing. And green led above backp button on.

The display will show "ReadyNAS" with nothing present except 5V, so there are many possibilities.

Sounds like time to try USB recovery.  You never got to the point of installing OS6, right?  So, a standard OS4.2.31 recovery is called for.  It could be the power supply or something else (lots of re-booting can stress an old PSU and other components).  If the USB recovery doesn't work, then further investigation is best performed by first installing a VGA cable and monitor onto the VGA header located on the motherboard and seeing if it's even getting through motherboard POST.  

Never installed OS6. https://kb.netgear.com/30267/RAIDiator-4-2-USB-Recovery-Tool never worked so far. I follow the rules and create a usb but it is not comming in recovery modus or any modus.

Legacy units are very picky about the USB drive you use, so you should try a couple more if you have them.
