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??

I have been able to telnet in to the dead NAS but i can't for the life of me figure out what is the proper command to mount the drive so I can copy the VPD file from another NAS.

dmesg | grep -i 'disk'

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.

  # 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

  Six drives ...
  
  As Sandshark's first post said, the vpd device and the usb stick is after the hard drives. One is sdg, the other is sdh.
  
  If you only have the Sandisk Cruzer attached with USB, then it looks like you want to mount sdh1

    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
