Hi,

I'm trying to connect a new oVirt Engine Version: 4.1.2.2-1.el7.centos to a Dell MD3200i SAN.
I can discover the SAN from the storage new domain window but when I login, instead of seeing the + symbol I get the "Could not retrieve LUNs, please check your storage" error message.
I tried with both a raw LUN and with a partitioned LUN but still no luck.
Any idea what could cause the problem?

Here some commands and logs
