CIMC Firmware Management
This chapter includes the following sections:
- Overview of Firmware
- Obtaining CIMC Firmware from Cisco
- Installing CIMC Firmware from the TFTP Server
- Activating Installed Firmware
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:
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.
Obtaining CIMC Firmware from Cisco
What to Do Next
Install the CIMC firmware on the server.
Installing CIMC Firmware from the TFTP Server
Note |
If you start an update while an update is already in process, both updates will fail. |
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | Server# scope cimc | Enters the CIMC command mode. |
| Step 2 | Server /cimc # scope firmware | Enters the CIMC firmware command mode. |
| Step 3 | Server /cimc/firmware # update tftp-ip-address path-and-filename | Starts the firmware update. The server will obtain the update firmware at the specified path and file name from the TFTP server at the specified IP address. |
| Step 4 | (Optional) Server /cimc/firmware # show detail | Displays the progress of the firmware update. |
This example updates the firmware:
Server# scope cimc
Server /cimc # scope firmware
Server /cimc/firmware # update 10.20.34.56 /user/updates/filename
Activate the new firmware.
Activating Installed Firmware
Install the CIMC firmware on the server.
Note |
If you start an activation while an update is in process, the activation will fail. |
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | Server# scope cimc | Enters the CIMC command mode. |
| Step 2 | Server /cimc # scope firmware | Enters the firmware command mode. |
| Step 3 | Server /cimc/firmware # show [detail] | Displays the available firmware images and status. |
| Step 4 | Server /cimc/firmware # activate [1 | 2] | Activates the selected image. If no image number is specified, the server activates the currently inactive image. |
This example activates firmware image 1:
Server# scope cimc
Server /cimc # scope firmware
Server /cimc/firmware # show detail
Firmware Image Information:
Update Stage: NONE
Update Progress: 100
Current FW Version: 1.0(0.74)
FW Image 1 Version: 1.0(0.66a)
FW Image 1 State: BACKUP INACTIVATED
FW Image 2 Version: 1.0(0.74)
FW Image 2 State: RUNNING ACTIVATED
Server /cimc/firmware # activate 1
