Cisco Upgrade Bug

NEXUS

It is recommended to have at least one image file for an older version as a rollback incase it does not successfully take the new image.

Check space for bootflash and the supervisor module,

#dir bootflash

#dir bootflash://sup-standby/

If there is not enough space remove unnecessary files.

#delete bootflash:'filename'

or

#delete bootflash://sup-standby/nxos.9.2.1.bin

Download the chosen software package: Software Download

Copy the image file to the switch.

#copy tftp://<server_ip>/nxos.<version>.bin bootflash:
or
copy usb1:nxos.<version>.bin bootflash:

You will want to show the checksum and compare to the one provided to be sure it's not corrupt or incomplete.

#dir bootflash
#show file bootflash:nxos.##.#.#.#.bin md5sum

Make sure you copy the running config to nvram.

#copy run start

Install the epld image if needed.

#install all nxos nxos.##.#.#.bin epld n9000-epld.##.#.#.img
#install all nxos nxos.##.#.#.IJD9.0.59.bin epld n9000-epld.##.#.#.F.img

Finally install the boot image.

#install all nxos bootflash:nxos64.10.2.1.F.bin
