Starting and stopping managers

After adding the storage systems to the management group, start managers on the additional storage
systems in the management group. The number of managers you start depends upon the overall design
of your storage system. See
managers to add.

Starting additional managers

1. In the navigation window select a storage system in the management group on which to start a
manager.
2. Click Storage System Tasks on the Details tab, and select Start Manager.
Repeat these steps to start managers on additional storage systems.

Stopping managers

Under normal circumstances, you stop a manager when you are removing a storage system from a
management group. You cannot stop the last manager in a management group. If you stop a manager
that compromises fault tolerance, the management group displays the icon indicating an item needs
attention.
Deleting the management group is the only way to stop the last manager.
Implications of stopping managers
• Quorum of the storage systems may be decreased.
• Fewer copies of configuration data are maintained.
• Fault tolerance of the configuration data may be lost.
• Data integrity and availability may be compromised.
