CLUSTERED STORAGE SYSTEM PATH QUIESCENCE ANALYSIS

摘要

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.

1. A method comprising:
receiving, at a first node, a request that indicates a component, wherein the component can be quiesced; determining that quiescence of the component might impact an endpoint; sending, to a second node, a request for identification of at least one path between the second node and the endpoint; determining whether the endpoint will be accessible to the second node if the component is quiesced, wherein said determining is based, at least in part, on receiving, from the second node, a response to the request; in response to determining that the endpoint will be accessible to the second node if the component is quiesced, indicating a positive analysis outcome; in response to determining that the endpoint will not be accessible to the second node if the component is quiesced, indicating a negative analysis outcome.
