Upgrading Nexus 9508 NX OS

  1. Backup the running config off of the switch
  2. Verify you have sufficient space on both Sup’s; delete older unused file images (not the current image!) if required

    dir bootflash://sup-local/

    dir bootflash://sup-standby/

  1. Copy the image to the active Sup.  I find FTP the easiest

         copy ftp://user@<ftp-IP>/nxos.7.0.3.I2.2d.bin bootflash: nxos.7.0.3.I2.2d.bin

  2. Verify checksum

    show file bootflash://sup-1/nxos.7.0.3.I2.2d.bin sha256sum

                    Result should be:

    d02606aba9f95563d1be810f4b5c0795db5c87ee50f5e552dc4de9015264d18b4ab69e3ad51558e19e04046d3c4319c8378b0ad6d493b8cdcb25a12d7c6806f4

  3. Verify install impact

    show install all impact nxos bootflash:nxos.7.0.3.I2.2d.bin

  4. Save the running config

    copy running-config startup-config

  5. Launch the install script.  For the current version it will be impactful (forced reload)

    install all nxos bootflash:nxos.7.0.3.I2.2d.bin
