Verify the storage system is not running a manager
Verify that the storage system that needs the disk replacement is not running a manager.
1. Log in to the management group.
2. Select the storage system in the navigation window, and review the Details tab information.
If the Storage System Status shows Manager Normal, and the Management Group Manager
shows Normal, then a manager is running and needs to be stopped.
To stop a manager:
1. Right-click the storage system in the navigation window and select Stop Manager.
When the process completes successfully, the manager is removed from the Status line in the
Storage System box, and Manager changes to No in the Management Group box.
2. If you stop a manager, the cluster will be left with an even number of managers. To ensure
that the cluster has an odd number of managers, do one of these tasks:
• Start a manager on another storage system.
• Add a virtual manager to the management group by right-clicking on the management
group name in the navigation window and selecting Add Virtual Manager.
Repair the storage system
Use the Repair Storage System function to replace a disk and trigger only one resynchronization
of the data.
