Important Pre-OS Upgrade Notes
Please consider the following items prior to upgrading the operating system:
- Upgrading modular switch systems can take up to 30 minutes during which time the system is indisposed 
- Upgrading the OS while embedded SM is enabled may cause the command “no hostname” to fail upon first execution. To resolve this, rerun the command 
- The upgrade procedure burns the software image as well as the firmware should there be a need 
- Before upgrading the software image on your system, make sure to close all CLI sessions besides the one used to run the upgrade process 
- If running a system with dual management cards, refer to “Upgrading MLNX-OS Software on Modular Switches” 
- To upgrade the MLNX-OS version on an SM cluster, please refer to “Upgrading HA Groups” 
- The End-User License Agreement (EULA) must read and accepted after image upgrade in case the EULA is modified. The EULA link is only available upon first login to CLI 
- Linux docker container names are limited to 180 characters. Upgrading to this version removes containers which do not comply with this limitation and prints the following warning to the log: “Removed configuration of container: <container name>, container name is limited to 180 characters”
