I am running a DS4200 IBM SAN box with dual controllers connected to 2 brocade switches . One of the servers has 2 single port Qlogic HBA's connected to each switch. LUN #3 and #4 have been setup on the Storage array and connected to the server. The server picks up each LUN twice. The SAN works fine and windows only allows connection to 1 instance of each of the LUNS. Multipath is being used by the IBM storage manager. What could be the reason why 2 LUNS are shown under windows 2003 server logical disk manager

Thanks. We'll let you know when a new response is added.

The IBM multipathing software is not working correctly. Check the Application log, or any logs which the IBM multipathing software is creating to see if there are any errors.
