SEFVDNotification

This event indicates to the host that it should respond in some appropriate manner to the reduced capacity condition.

This event is issued at the Virtual Device level. Due to failure of blocks, actual available capacity may fall below the allocated capacity of the attached QoS Domains. The host should take action to release super blocks back to the Virtual Device's free pool before it is entirely consumed.
