Critical Warning on Active Controller, steps to swap controller while running
Hello,
Dell PS6610 Raid 6, am able to log into Equallogic Group Manager.
The battery in our EQL primary controller is currently under a critical warning and needs to be replaced. While we wait on that part to arrive we're seeing latency issues with data transfers due to the failing controller. How do we tell our Equallogic to swap to the controller that has no current potential hazards? Will it require the device to be powered down or can this happen without having to shut down all connected machines and then the datastore?

Hello,
If it is the Active you need to make the controller secondary before pulling.

To make the controller module secondary:

Hello,
In the GUI, select the member, then in the Maint tab there will be an option to restart the controller.
Or at the CLI you can issue a 'restart' which will also cause the primary to failover to the secondary.
While the failover process is usually very fast, if you have not set your hosts in compliance with the best practices your servers could timeout during the failover.
Regards,
Don
