Firmware Upgrades for Cisco UCS Domains
You can deploy infrastructure and server firmware upgrades for registered Cisco UCS domains from Cisco UCS Central.
If desired, you can upgrade the Cisco UCS domains in each domain group with different versions of firmware. Cisco UCS Central also provides you the option to acknowledge the fabric interconnect reboot globally from Cisco UCS Central or individually from each Cisco UCS domain.
Configuring an Infrastructure Firmware Upgrade for a Cisco UCS Domain
You can create only one infrastructure firmware package for one Cisco UCS Domain group in Cisco UCS Central . The member Cisco UCS domains in a domain group will run the same infrastructure firmware version.
Note | You can configure infrastructure firmware update from domain group root or at the domain group level. When you update the firmware at the domain group root level, all the domain groups under the root will get the same infrastructure firmware version. |
What to Do Next
Cisco UCS Central automatically creates two schedules for infrastructure firmware update and fabric interconnect reboot. These schedules are also updated in Cisco UCS Manager. Based on the schedule, the infrastructure firmware upgrade process begins in the registered Cisco UCS domains and generates the first acknowledge pending activities message in Cisco UCS Central. When you acknowledge the first pending activity, the components are updated with the specified infrastructure firmware package.
After the infrastructure firmware is updated, you will receive another pending activity notification. This acknowledgment prevents any accidental reboot of fabric interconnects. You have to acknowledge this pending activity to reboot the fabric interconnect and complete the infrastructure firmware upgrade.
Note | If you have multiple domains in a domain group, you will have acknowledge each pending activity for each Cisco UCS domains to complete the infrastructure firmware upgrade process. |
Acknowledging a Pending Activity
if the service profiles in Cisco UCS domains use a global maintenance policy and global host firmware package, Cisco UCS Central provides you an option to enable user acknowledgment before deploying the firmware upgrade.
If you have created a maintenance policy with User Ack reboot policy, you must acknowledge the actual firmware upgrade in Cisco UCS Manager. If you have created a maintenance policy with a global schedule and enabled User Ack, you must acknowledge the actual upgrade for all Cisco UCS domains in Cisco UCS Central.
Note | You can view and acknowledge pending activities from Infrastructure Firmware and Host Firmware sections. This procedure describes the process to acknowledge a pending activity from the host firmware section. |

Creating a Host Firmware Package
What to Do Next
The host firmware policy you create in Cisco UCS Central will be available for association to a service profile in a Cisco UCS Domain registered to a domain group.
Deploying a Host Firmware Upgrade
You can update all host firmware policies defined in Cisco UCS Central to specific B, C, and M bundles using the Install Servers.
You must have created a host firmware package.

Scheduling Firmware Upgrades
Firmware Upgrade Schedules
To upgrade firmware by domain groups in registered Cisco UCS domains, you can schedule upgrades from Cisco UCS Central in the following ways:
If you configure the schedules for user acknowledgment, the fabric interconnect will not reboot without explicit acknowledgment.
Creating a Maintenance Policy
You can create the following types of maintenance policies for host firmware update in Cisco UCS Central:
-
Immediate — The immediate option reboots the servers immediately without any user acknowledgment.
-
Timer-automatic — In timer-automatic option, the server reboot will happen based on the schedule you select for this maintenance policy.
Important: If you use the timer automatic option, you must create a schedule in Cisco UCS Central to specify in the maintenance policy. When you create a schedule in Cisco UCS Central, you can acknowledge this scheduled maintenance policy only in Cisco UCS Central.Servers using this maintenance policy will reboot only during the maintenance window defined in the schedule. If user-ack is enabled in the schedule, then you must acknowledge the server reboot.
-
User-acknowledgment — The user-ack option sends a pending activity notification in each Cisco UCS Domain before rebooting servers.
Important: The user-ack option provides Cisco UCS domains administrators the option to decide on rebooting servers in individual Cisco UCS domains at different times.
What to Do Next
Associate the maintenance policy to a service profile in Cisco UCS Manager.
