Platform-specific prerequisites
Before you upgrade, ensure that the following prerequisites are met:
All platforms
Ensure that you back up the configuration data and license files in an external storage.
If you have VLT enabled, ensure that you make note of the X.509v3 security profile name to reinstall the X.509v3 certificate
after upgrade. Use the show crypto cert command to view the security profile name.
S4100-ON platform
If you are upgrading OS10 from Release 10.5.0.x or earlier to Release 10.5.1.9 or later on an S4100-ON series platform, you
must ensure that the realpath variable in OS10-Boot is set to /dev/sda4. To check the realpath variable, enter the
system "realpath /dev/disk/by-label/OS10-BOOT" command from the OS10 CLI:
OS10# system "realpath /dev/disk/by-label/OS10-BOOT"
If the realpath variable is:
Set to /dev/sda4, proceed with OS10 upgrade.
Not set to /dev/sda4, you must uninstall the existing OS10 version and reinstall the new version of OS10. To do this:
1. Back up the current running configuration (Release 10.5.0.x or earlier) to an external storage.
OS10# copy running-configuration scp://userid:passwd@hostip/filepath/
runningconfiguration.txt
2. Reload the switch and watch for the ONIE boot menu.
3. Use the arrow keys to scroll and select ONIE: Uninstall OS option.
4. After you reload the switch again, from the ONIE boot menu, select the ONIE: Install OS option and install
Release 10.5.1.9 or later release. See Installing SmartFabric OS10 section for more information.
