Known Affected Releases

4.0(4g)A 4.1(1a)A

Description (partial)

Symptom:
UCS FC ports can stay online when upstream MDS experiences a kernel panic.

Depending on configuration, this can cause UCS FC uplinks to stay online even though MDS is inoperable, causing pinned vHBAs to stay up which leads to the OS being unaware that FC interfaces are not functioning properly.

Conditions:
6454 FIs running UCSM 4.0(4g) firmware connected to upstream MDS.
