POAP USB N9K

[georg-seidl]

Hi everbody,

i try poap usb with a N9k 10.3.5m NXOS. With paop script from git.

nexus9000/nx-os/poap/poap.py at master · datacenter/nexus9000 (github.com)

After some troubleshooting i have changed poap sript

line 1075 copy_src=os.path.join("/usbslot%s" % (options["usb_slot"]), source)

to

line 1075 copy_src=os.path.join("/usb%s" % (options["usb_slot"]), source

and follwing lines. But i have always the same problem conf.FDO24320BVX does NOT exist.

Have anybody working example with N9K?

Thanks & best regards

I think the problem is that usbstick is in guestshell not mounted

I start default guestshell, i could find usbstick directory like as /bootflash

[t00000skea@guestshell ~]$ cd /
[t00000skea@guestshell /]$ ls
afs boot cisco cscogsart-1.0-0.x86_64.rpm etc isan lib64 lost+found mnt proc run selinux sys usr volatile
bin bootflash created.2023-12-08.11:19:14 dev home lib logflash media opt root sbin srv tmp var
[t00000skea@guestshell /]$ cd media
[t00000skea@guestshell media]$ ls
[t00000skea@guestshell media]$

Not found any docs on this, but do you use guestshell run mount /dev/sdb1 /media/usb for this? I think you can see the USB in guestshell via mount | grep usb - not tried this in ages however...

[georg-seidl]

thats the problem no good documentation is available

i have tried this

[user01@guestshell /]$ sudo fdisk -l   -> no stick to see? in nxos cd usb1: is possible

[user01@guestshell /]$ sudo mount /dev/sdb1 /media/usb1
mount: /media/usb1: permission denied.

@georg-seidl might have gotten lucky with this find https://github.com/ndelecro/nx-os-programmability/blob/master/Guest_Shell/PXE_Server/README.md

bash-4.2$ sudo su
bash-4.2# mount --make-shared /usbslot1
bash-4.2# mkdir /var/run/netns/usbslot1
bash-4.2# mount --bind /usbslot1 /var/run/netns/usbslot1

Based on this info, i have changed the poap_script.py back.

If i do this manuelly (bash mount) so i can access the usbstick my guestshell.

So i have found my failure.

"config_path": "/baseline" the slash was the problem "config_path": "baseline" works.
