Have a MD3220 with two SAS controllers. Both controllers assigned static IP's (172.16.10.x). Have a PE R610 server loaded with win 2012 R2 and have MDSM loaded on there and its connected to same network as the SAN. Every few hours the software loses connection to the SAN and i cant figure out why.. I have to right click on the SAN in the software and remove it.. then do a new discovery and it adds it back in. Once i do this it shows optimal for a few hours until it loses connection and says unresponsive again.. What gives?
In your post you state that you are having an issue with your MD1220 but the Picture is showing an MD3220? I am guessing that you missed typed MD1220 & it should be MD3220? When you installed your MD3220 did u follow the Deployment Guide for setting up the management? Here is the guide if you need it. http://downloads.dell.com/manuals/common/powervault-md3200_deployment%20guide_en-us.pdf
Also when you lose connection to your MD3220 & you get it back are there any error listed in the Recovery guru?
