Can't access ReadyNAS Pro 6
Hello friends, As the title says, I have an old RNDP6000 and I can't access it. It had been turned off for a long time. I'm using Windows 11 Pro. Its readout shows it is on and displays it...

Thanks, StephenB , I think I would like to convert to OS-6 and upgrade the memory sticks as well. I've got all the files on my other NAS, so nothing will be lost.
I was able to install the .bin file, but not sure I did it in the right sequence. (I installed it before updating RAIDiator.)
You all have been very helpful. I hope I can get this to be a healthy working NAS now, with your guidance. What should I do? I'm ready.

If https://192.168.0.2/admin works from Chrome, Edge, or Safari then the add-on is doing its job.

After the RAM upgrade:
If you have the skills, you should probably back up the VPD before conversion. The VPD is in aging flash memory, which sometimes gets corrupted. If you have a copy, you can attempt to restore it when/if that happens. fMore information on this is here:
The conversion steps are
(Optionally) make sure the latest BIOS is installed before you do the conversion. To do this you install http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin as an add-on and reboot the NAS. Do this after you backup the NAS. This isn't necessary, but if you do want to update the BIOS it is easiest to do it prior to conversion
Basic instructions for the conversion itself are
- BACKUP, BACKUP, BACKUP
- Upload PREPR4TOR6_0.1-x86.bin as an add-on using the ReadyNAS web gui, but do not reboot afterwards (avoids the need to do manual factory resets)
- Upload R4toR6_6.9.5.bin using the ReadyNAS web gui firmware update
- After you upload the addon+firmware and reboot, it will update the firmware and start a factory default.
- Go through the setup process on the converted NAS
- Update the NAS to either 6.10.9 or 6.10.10 (check for updates will NOT work, you will have to do this manually).
- Restore files from the backup.
There is a small risk that the process could fail, and if that were to happen it might not be possible to get the NAS running again.
Installing add-ons is difficult, so best avoided.
Note that if you ever need to do a USB recovery later on, you will need to use the procedure for 4.2 systems - substituting an OS-6 image for the 4.2.31 one.
