Backup and restore of VPD file for legacy ReadyNAS running oS6
We have recently seen a rash of errors reported here on legacy machines upgraded to OS6 that are associated with a corrupt VPD (Vendor Product Data) file. This doesn't usually occur when the NAS is c...

While i have not been to a linux command prompt in years none of these articles tell me how to mount the firmware mount location on the dead NAS??some simple command to find the location where the corrupt VPD file is would be helpful 🙂
How many hard drives are installed?
Normally the hard drives start with sda, and you'd try the ones after them. For instance, if you have 4 disks installed, you'd start with sde1, and see if that is the correct one.
Six drives as it states in the info above. It was in a XRAID Raid 5 array. All my devices are the same configurations. Some a few different model numbers but overall the same architecture.
Thanks
# is the standard Linux command prompt.
It clearly states you use a command in the form mount /dev/sdc1 mnt . You only have to figure out which drive it is. Usually, on a 6-drive unit, it will be sdg (the 7th drive), so you mount the first partition on it, sdg1. You can use ls/dev/sd* to see the drives and partitions. It will be one of the drives with only one partition (the USB drive is the other) There aren't a lot of tools installed in the tech support mode to find it any easier.
I do not give "blow by blow" instructions for a reason. Telnetting (or SSHing in normal boot mode) into a NAS allows you to do many things you should not and can cause big issues with it. Frankly, if you cannot follow the instructions, maybe with a little help from Google, you probably shouldn't doing it.
Given the fact that the unit is currently bricked I think that we are past the point of me messing something up 🙂
FYI it was not 7th as that was the USB drive i was told to put in to copy the VPD file from. It was the 8th drive and yes the VPD file is there - have no idea whether it is corrupt but assume so.
I have the following 4 ReadyNAS units:
1) RNDP6350-100NAS - ReadyNAS Pro - RNDP6350
- this is the bricked unit
2) RNDP6350-100NAS - ReadyNAS Pro - RNDP6000
3) RNDP6000 - RND-6B - RNDP6000
4) RNDP6000 - RND-6B - RNDP6000
These all appear to be similar models and units which were purchased at different times.
My question is will any of these allow me to properly copy their VPD file across over the broken one to try and get back to a running state?
The other 3 are running and healthy.
Thanks
Yes figured that out but the key thing is can i copy an VPD file from another NAS.
I just had another one fail after upgrading to 6.10.9 with the same problem in Raidar 😞
So now i have two bricked ones.
Can anyone help me rebuild the VPD file for these?
Or is this a lost cause and I just need to give up and toss these units?
I will note that the 1st one that failed maybe due to a power supply issue as one of the fans on the power supply no longer works 😞
The second one was find but seems like it might be similar?
I ordered a power supply off of ebay to see if swapping that out might resolve something.
However, without a good VPD file I can't do much 🙂
Thanks in advance
Yes, you can copy the VPD from either of the un-bricked units. In the model number RNDP6xxx, the xxx just indicates how many drives the unit shipped with. The ones with the copied VPD will report the same serial number as the one it was copied from, but that would only have been a problem getting Negear support or with ReadyCloud, neither of which is now available.
I agree that your NAS can't be messed up much more, but you are not the only one that will read this email chain. So I stand by my policy of requiring users to do a little work and understand my instructions, not just type them in verbatim, especially when they can change some from NAS to NAS. As for the order of the flash and the USB drive, I guess it matters which model NAS you have. I ran my experiments on a "sandbox" Pro2 and the USB drive was first after the hard drives.
Your experience is another attestment that installing/updating to OS6.10.x can corrupt the VPD and that that all legacy ReadyNAS users. especially those running OS6, should back up their VPD. It's especially important now that there seems to be nobody at Netgear who can/will provide a repaired one. It's good that you have units to copy from -- most don't.
