The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter includes the following sections:
All endpoints in a Cisco UCS instance must be fully functional and all processes must be complete before you begin a firmware upgrade or downgrade on those endpoints. You cannot upgrade or downgrade an endpoint that is not in a functional state. For example, the firmware on a server that has not been discovered cannot be upgraded or downgraded. An incomplete process, such as an FSM that has failed after the maximum number of retries, can cause the upgrade or downgrade on an endpoint to fail. If an FSM is in progress, Cisco UCS Manager queues up the update and activation and runs them when the FSM has completed successfully.
Before you upgrade or downgrade firmware in a Cisco UCS instance, complete the following prerequisites:
This procedure assumes that you do not have an existing backup operation for an All Configuration backup file.
For more information on backing up a Cisco UCS instance, see the Cisco UCS Manager GUI Configuration Guide and the Cisco UCS Manager CLI Configuration Guide.
Obtain the backup server IP address and authentication credentials.
The high availability status is the same for both fabric interconnects in a cluster configuration.

Step 5 |
For each I/O module, verify that the following columns display the following values:
If the values are different, create and download a Tech Support file, and contact Cisco Technical Support. Do not proceed with the firmware upgrade. For more information about Tech Support files, see the Cisco UCS Manager B-Series Troubleshooting Guide. |

Step 6 | Repeat Steps 3 through 5 to verify the status of the I/O modules in each chassis. |
If a server is inoperable, you can proceed with the upgrade for other servers in the Cisco UCS instance. However, you cannot upgrade the inoperable server.
Step 1 | In the Navigation pane, click the Equipment tab. | ||||||
Step 2 | On the Equipment tab, click Equipment. | ||||||
Step 3 | In the Work pane, click the Servers tab to display a list of all servers in all chassis. | ||||||
Step 4 |
For each server, verify that the following columns display the following values:
|
||||||
Step 5 |
If you need to verify that a server has been discovered, do the following:
|
Step 1 | In the Navigation pane, click the Equipment tab. | ||||||
Step 2 | On the Equipment tab, expand . | ||||||
Step 3 | Click the server for which you want to verify the status of the adapters. | ||||||
Step 4 | In the Work pane, click the Inventory tab. | ||||||
Step 5 | In the Inventory tab, click the Adapters subtab. | ||||||
Step 6 |
For each adapter, verify that the following columns display the following values:
If the fields show a different value and the adapter is inoperable, you can proceed with the upgrade for other adapters on the servers in the Cisco UCS instance. However, you cannot upgrade the inoperable adapter. |
