Dell MD3000i Active/Active

Hey guys,

I have a PowerVault 3000i storage array and I'm setting up iSCSI MPIO. I''m pulling my hair out why I'm seeing in VMware ESXi 6.5 that the MPIO is showing up as Active/Passive instead of Active/Active in VMware...

I must have tried setting this up in a variety of ways but I'm still getting Active /Passive. Any help would be greatly received? 

Thanks,

Martin
