The maintenance policy is a very important policy that controls the server's response to any changes in the service profile. Many service profile changes need a reboot of the server to take effect. It is therefore recommended to configure this policy with user acknowledgment settings for production environments so that servers can be rebooted in a controlled change management window.
Following are the steps to create a maintenance policy.
- Log in to UCS Manager.
- Click to expand the Servers tab in the navigation pane.
- Click on the Policies tab and expand root.
- Right-click on the Maintenance Policies tab and on the pop-up screen that appears, click on Create Maintenance Policy:
- Assign a Name and a short Description to the maintenance policy.
- Setting a value for Reboot Policy is critical. Immediate means the server will be instantaneously rebooted for changes that require a reboot, which is not a recommended setting for production servers. User Ack means that any change that requires a server reboot will be held until the user's acknowledgement. This setting allows scheduling a maintenance window and rebooting the server following proper procedures. Timer Automatic allows you to schedule a maintenance window and automatically reboot the server at a specific time without an administrator's intervention:
