Hi Dell Community, 

We have 2 Raid Controllers on our MD3400 Storage Array.

We have 2, 6.0 ESXi hosts connected to the Dell MD3400 Storage Array via SAS cables and cards. When checking The storage adapter( SAS cards)on the Vsphere hosts 1 host correctly shows 2 Active connections and 1 host only shows 1 Active Connection.

The cabling looks correct. On the MDSM software each host has 2 port identifiers assigned , but I do see there is a 5th identifier not assigned.

Other notes, Host interfaces shows channel 4 port 3 down.

Also on the host mappings the host that does not have both Active ports available does not have the default Access 31 group and the second host that is working correctly does, i am not sure if it was removed and has to be in mapping for that host too?

The host group that contains both hosts does have the Access 31 Group

Thank you
