Upgrading a Cisco MDS 9500

We recently performed some upgrade our Cisco MDS 9509 and thought we’d share the steps with you. You’re welcome to hop on Cisco.com as well and grab the user guide, but if you’re running a 9500 with redundant Sup-2’s, this should be all you need to hop between SAN-OS 3.x versions and all the way up to NX-OS 5.x…

  1. Review upgrade guide from Cisco.com
  2. Download new system and kickstart software from Cisco.com
  3. Upload new software via TFTP to MDS
    • Start SolarWinds TFTP Server on MDS-reachable system (make sure it isn’t firewalled!)
    • Configure TFTP Server to look in the local directory where you copied the software
    • Make sure the TFTP Server is started (Configure > Start)
    • Open a telnet (Putty) session to the MDS (or SSH, if you prefer/use that)
    • Upload system software: i.e. # copy tftp://192.168.1.10/m9500-sf2ek9-mz.4.2.7d.bin bootflash:
    • Upload kickstart software: i.e. # copy tftp://192.168.1.10/m9500-sf2ek9-kickstart-mz.4.2.7d.bin bootflash:
  4. Assess impact of upgrade to MDS
    • # show install all impact system bootflash:m9500-sf2ek9-mz.4.2.7d.bin kickstart bootflash:m9500-sf2ek9-kickstart-mz.4.2.7d.bin
    • If all “verifying” steps return “SUCCESS” and the modules listed show “non-disruptive”, proceed with installation
  5. Install software (example below)
    • # install all system bootflash:m9500-sf2ek9-mz.4.2.7d.bin kickstart bootflash:m9500-sf2ek9-kickstart-mz.4.2.7d.bin
  6. Software upgrade will reboot the supervisor modules which will require reconnecting via Putty to monitor the remainder of the upgrade
  7. After upgrade is complete:
    • Save the running config to startup: # copy run start
    • Backup the running config via TFTP: i.e. # copy run tftp://192.168.1.10/mds9509-config-20110127-4.2.7d.cfg
