Device Image Management

Using maintenance mode, you can download firmware on one or more devices in the IP fabric with minimal disruption to data path traffic. Both Clos and small data center (non-Clos) fabrics are supported. The maintenance mode feature is supported only on SLX devices running SLXOS 20.1.1 and later.

EFA supports the following firmware download features.

• Firmware download with maintenance mode supporting the following:
  • Asynchronously launched operations
  • Sanity and pre-install script verification
  • Set convergence timeout, enable, and disable
  • Persisting the running configuration so that running configuration and maintenance mode configuration are preserved after reboot
  • Firmware download with the no commit option to enable restoration of firmware to a previous version
• Firmware host registration, with support for register, update, delete, and list operations
• Firmware download preparation, with support for add, remove, and list operations
• Firmware download with the show option, to display a table of devices in the fabric and their corresponding status

Limitations

• The device firmware must be SLX-OS 20.1.1 or later to support firmware download with maintenance mode for a hitless firmware upgrade.
• This feature assumes an existing host that contains SLX-OS firmware images ready to be downloaded.
• You can use this feature on a device where EFA TPVM is deployed, as long as you follow the instructions in Extreme Fabric Automation Deployment Guide, 2.7.0 .
• If you downgrade software from version 20.1.2a to 20.1.1, you must manually remove certificates.
