[j-nsp] J-Series and USB storage

[Jonathan Crawford]

Stacy,

If he is having the same issue as me, the issue is not the hardware being recognized... mine shows up in "show chassis hardware detail", as well as showing up in dmesg as being available, as well as being able to be mounted from shell, etc... however, the cli app refuses to see the device giving "error: usb media missing or invalid". I can place the same USB drive in another J series and it works fine.

It shouldn't require a reboot to recognize the USB, but assuming a
reboot makes it show up in the "show chassis hardware detail" output,
you should then be able to proceed with the "request system snapshot
partition swap-size 0 media usb" command in step 2 of those directions.

In this case, you do want to keep the "swap-size 0" argument in order
to remove the swap partition. I still think the "as-primary" keyword
is unnecessary.
