How to Failover Management Module on Your MX7000 Chassis
Publication le Aug 26, 2024
Here's how to failover a Management Module (MM) in OpenManage Enterprise Modular (OME-M).
Hello, everyone.
My name is Cynthia, and I am a global support engineer specializing in modular systems and the MX7000 chassis.
Today, we are going to cover how to failover management modules. This requires logging into an account with chassis administrator privileges.
A failover is the process of transferring the active role to the standby management module. A reboot of the active management module will take place and the standby management module will assume the active role.
So, let's go ahead and access the chassis that we're wanting to failover management modules on. From here, we will select "More Actions" and "Failover".
This failover operation can take up to 10 minutes for completion. During part of the process, OpenManage Enterprise Modular will be unavailable.
You can perform continuous pings until it comes back up. For the sake of this video, the process has been sped up. After logging back in, you can go and monitor the job from "Monitor Jobs", and see the "Job Completion" status.
We'll go ahead and go back to the chassis that we performed the failover operation on. From "Hardware", "Management Module", you can see which management module is "Active" and which is "Standby".
On the right, you will see a management module redundancy error, and you'll see that the chassis is performing reinventory jobs. Over time, the "Recent Alerts" will change.
If your chassis is in a group, you may also see a redundancy error in regard to the chassis group. Since it's completed, we will see a message that the "Management Module is redundant" again.
And then we will see a message that the "Device health has improved". Eventually, the chassis "Health" status will also transition from a "Critical" state back to an "Ok" state.
If your chassis is in a group, you will see that the "Redundancy feature" of the chassis group is restored. The message on the right side regarding the redundancy of the management module will also disappear over time.
And now, our chassis is in a perfectly healthy state. And the failover process is complete. And that is all for this video.
