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.

some simple command to find the location where the corrupt VPD file is would be helpful 🙂

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.
