Because duplicated GUIDs detector can aborts OpenSM when regular port is reconnected to another location during hard sweep. This issue is not related to loopback plug at all. > The issue is only if a "loop back" plug connecting a port to itself is > plugged. No, not only. Now there are two completely separate known issues with duplicated GUIDs detector: 1. Port moving 2. Loopback plug And I think that _both_ should be solved. And if just using '-y' could be suitable for (2) because it is esoteric (although perfectly legal) use, it is not acceptable solution for (1). I think we need to improve GUIDs duplication detector instead. For example we could add NodeInfo comparison there, and only in case if it is different drop GUIDs duplication error. Also I think this should not be fatal error and should not abort OpenSM, just logging (probably via syslog too) should be sufficient - non-working port is good reason to look at logs. Another ideas?
