Hello,
I have an MD3000 (enclosure 0) with a MD1000 expansion shelf (enclosure 1). Intermittently the fans will spin up for anywhere from 5 seconds to a couple of minutes. On the MD1000 the status lights blink orange one EMM then the other. MDSM reports "Enclosure 1 EMM failure in Unknown". It will then correct itself with no intervention. There is no loss of communication or performance impact.
I have now replaced every item (including the chassis) in the MD1000 except the drives and cables and still get this intermittent issue multiple times a day.
Any advice on how to further diagnose or what action I should take would be appreciated.
Morgan
