Some time ago i posted how to convert a ACI switch to NX-OS, now the other way around.
Copy the file to the NX-OS Mode N9k
switch# copy scp: bootflash: Enter source filename: Downloads/aci-n9000-dk22.214.171.124o.bin Enter vrf (If no input, current vrf 'default' is considered): management Enter hostname for the scp server: 192.168.0.5 Enter username: USER Password: aci-n9000-dk126.96.36.199o.bin 1% 15MB 3.8MB/s 04:34 ETA
Change the boot mode to aci
switch(config)# boot aci bootflash:///aci-n9000-dk188.8.131.52o.bin Warning: Please check list of all ACI supported hardware before doing this operation, not all hardware are supported. Warning: Booting to an ACI image will remove all nxos configuration and format bootflash. Do you want to continue (y/n)?[n] y Performing image verification and compatibility check, please wait.... Image verification successful.
That’s it, just boot the switch and you can join the fabric 🙂
Be aware that the first reload can take quite some time! (15minutes+)
switch# reload !!!WARNING! there is unsaved configuration!!! This command will reboot the system. (y/n)? [n] y
