Nexus 9336PQ manual upgrade file gets always deleted

[as00001111]

Hi all!

I'm trying to upgrade a Nexus 9336PQ manually.

I copied the new aci image to bootflash but after 3 minutes it always get deleted.

Can you tell me why?

Furthermore, the image owner is admin:

-rwxrwxrwx 1 admin admin 1946977004 Apr 7 11:40 aci-n9000-dk9.14.2.3q.bin

When I want to change it, it says:

(none)# chown root:root /bootflash/aci-n9000-dk9.14.2.3q.bin
chown: changing ownership of `/bootflash/aci-n9000-dk9.14.2.3q.bin': Operation not permitted

Is there a way to do a sudo command to get sudo rights?

Can you tell me how to proceed with the upgrade?

I already changed the boot variables to the new image because the new image stays for 3 minutes in bootflash directory after it gets deleted.

I'm afraid I'm rebooting the switch and the new image is not available.

Thank you!

If this is part of ACI, i would expect APIC to upgrade ? or am i reading wrong here ?

Hey!

my apic is on version 14.2.3q and nexus 9336pq is on version 13.1.1i.

What do you suggest to do?

[as00001111]

is anyone able to help out here?

I copy the image into /bootflash/

immediately after I do a ls-l and the image disappears.

Why does the image not stay in /bootlfash/ ?

help is really appreciated.

1. Format USB as EXT4 o fat32.  USB needs to be lower than 64GB
2. Download ACI image file from cisco
3. Copy ACI image to USB
4. Connect to switch via console
5. Plug USB into the switch
6. Check USB file

Switch# dir usbslot1

Switch# dir usb1

Switch# dir usb

7. Check disk space

Switch# df -h /bootflash

Delete all NX-OS and ACI images if disk usage exceeds 50%

8. Copy new ACI image to switch

Switch# rsync --progress usbslot1/aci-n9000-xxxx.bin bootflash

9. Check that image was copied OK

I ran into something similar. In my case, I downloaded the 64-bit version of the ACI OS code and it mysteriously disappeared. After the 3rd time, I figured it was because the 64-bit version was not supported. So, I downloaded the 32-bit version (with no "64" in the name) and it stopped being deleted. I was able to upgrade to that version with no issues.
