Abstract: An indication of an event occurrence is received. The indication of the event occurrence is associated with a severity. A tag associated with the indication of the event occurrence is determined. It is determined whether the tag is the same as a preceding tag. In response to a determination that the tag is not the same as the preceding tag, a component is notified of the event occurrence, the tag is stored for later use, and an indication of the severity associated with the indication of the event occurrence is stored.

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.

Abstract: A request that indicates a component that can be quiesced is received at a first node. It is determined that quiescence of the component might impact an endpoint. A request for identification of at least one path between a second node and the endpoint is sent to the second node. It is determined, based on a response received from the second node, whether the endpoint will be accessible to the second node if the component is quiesced. In response to a determination that the endpoint will be accessible to the second node if the component is quiesced, a positive analysis outcome is indicated. In response to a determination that the endpoint will not be accessible to the second node if the component is quiesced, a negative analysis outcome is indicated.
