Just a short query: I have a Dell Md3200i setup to serve LUNs to my 2 physical hosts and I'm running vSphere/ESXi v5 with a number of VM's. Is it normal behavior for ALL VM's and LUN's to run off the one controller all the time? At the moment everything is running through Controller1.
I setup 2- 6 drive RAID10 arrays and wanted 1 array running via Controller0 and the other array via Controller1 to get a bit of load balancing going. But when I set 'Ownership' like that in the MD Manager it seems to migrate itself back to the one controller.
When I check the VM's MPIO modes in ESXi they all have 4 paths back to Controller1 as Active and 4 paths back to Controller0 as Standby.
I have played around pulling one controller out and it seems to all re-route itself to the other Controller. So it seems like its all via one controller at a time but just wanting to make sure I didn't screw something up in the setup ;)
Is this expected behavior??
