DS4500 Issues after Power cycle (link status going up/downrepeatedly)
I recently had to powercycle our DS4500 SAN unit. When it came up it
went through the normal checks and such, but the link lights on the mini-hubs never stopped blinking. What I am seeing now, both on the clients (a cluster of AIX systems) and on the storage manager is that all of the links are going up and down about once every three seconds. Believe it or not the unit is still functioning, but it is constantly changing paths (due to the ever changing link status), and this is cramming the error logs both on the AIX servers (where DAC reports an issue) and in the MEL. Storage manager shows no errors at all, and every device shows as 'optimal'. All diagnostic tests pass. I'm at a loss, and I hesitate to power cycle the unit again. I can't seem to find anyone else who has had an issue such as this. Any ideas? Much obliged, Randall Walls |
