Why are capacity alerts important?
Capacity alerts indicate when to add drives to a pool. A pool needs sufficient free capacity to successfully perform storage array operations. You can prevent interruptions to these operations by configuring System Manager to send alerts when the free capacity of a pool reaches or exceeds a specified percentage.
You set this percentage when you create a pool using either the Pool auto-configuration option or the Create pool option. If you choose the automatic option, default settings automatically determine when you receive alert notifications. If you choose to manually create the pool, you can determine the alert notification settings; or if you prefer, you can accept the default settings. You can adjust these settings later in.
When the free capacity in the pool reaches the specified percentage, an alert notification is sent using the method you specified in the alert configuration.
