CIMC Firmware Management

This chapter includes the following sections:

Overview of Firmware

C-Series servers use firmware obtained from and certified by Cisco to upgrade firmware on the server. After you have obtained a firmware image from Cisco, you can use it to update the firmware on your server. Cisco also provides release notes with each image, which you can obtain from the same website from which you obtained the image.


Note


When you update the firmware, you can either upgrade an older firmware version to a newer one, or downgrade a newer firmware version to an older one.


The CIMC separates the firmware update process into stages to ensure that you can install the firmware to a component while the server is running without affecting its uptime. Because you do not need to reboot the server until after you activate, you can perform that task overnight or during other maintenance periods. When you update firmware, the following stages occur:

Install

During this stage, the CIMC transfers the selected firmware version to the server. The install process always overwrites the firmware in the non-active slot on the server. You can install the firmware using either of the following methods:


  • Through a browser client—this method allows you to browse for a firmware image on your computer and install it on the server.

  • From a TFTP server—this method allows you to install a firmware image residing on a TFTP server.

Activate

During this stage, the CIMC sets the non-active firmware version as active and reboots the server. When the server reboots, the non-active slot becomes the active slot, and the active slot becomes the non-active slot. The firmware in the new active slot becomes the running version.
