The back-end IT path was found cycling between degraded and un-degraded five times within a 40 minute period due to intermittent poor performance, and is now considered "flap degraded".	Investigate the related switch logs and array performance for the IT nexus to determine the cause for the intermittent poor performance.The I-T path will be marked "flap degraded" until the user manually restores the use of the I-T path via VPlexcli command 'back-enddegraded recover', or the default 4 hour threshold is reached, after which the IT nexus will then be marked "performance degraded" while the recovery process checks its health before un-degrading it. If the intermittent latency issue continues on the I-T path, and the user is unable to address the root cause quickly then it is advised to engage Dell EMC Customer Service to manually isolate the IT nexus path to remove it from use until the underlying issue can be resolved.
