Abstract
An indication of an event is received at a storage controller. The indication of the event corresponds to a first severity. It is determined that the event is associated with a first stream of commands. It is determined whether the indication of the event is the first indication of the event received by the storage controller. If the indication of the event is the first indication of the event received by the storage controller, a maximum allowed count of in-flight commands to be less than a current count of in-flight commands is set. If the indication of the event is not the first indication of the event received by the storage controller, it is determined that the first severity is greater than a second severity corresponding to a previously received indication. If the first severity is greater than the second severity, the maximum allowed count of in-flight commands is decreased.
