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 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 Upgrade Device Firmware in a High Availability Deployment.
• If you downgrade software from version 20.1.2a to 20.1.1, you must manually remove certificates.
