https://community.hpe.com/t5/disk-enclosures/msa1000-showing-incorrect-function-in-disk-management/m-p/4791154#M37880 Hi, I have one MSA1000 with 2 controllers.<BR />Active standby configuration. I have connectd this MSA with Server 2008 R2 . Presented the LUN from the storage to the server. When I start initialise the disk from the windwos disk manager, I am getting the error "incorrecet function ". I am not able to do anything. I am using Microsoft MPIO. I am not able to see any HP MPIO for 2008 R2. <BR /><BR />When I disconnet the one of the controller , I can initialise and format the disk. <BR /><BR />The storage is using single port HUB for each controller and both the controller is connected to one compaq SAN switch.<BR /><BR />Any idea why I am getting this error , when I connect both the controller????
