Hi Gurus,

I've been working with a 10gb network setup with 3x VMware vsphere esxi host, both 5.5 and 6.0.  Been trying to create datastore via iscsi 10gb connections, but when going through the process to create the datastores, the hosts can see the iscsi targets just fine, vmkping is fine, but when I complete the datastore creation, it always bombs out with an error.  However, when I repeat the same process via 1gb connection on the same 10gb switch, the creation process completes without issue.

So the environment is 3x HP DL360p Gen 8 servers, with 2x 10GB SFP DAC connections and 2x cat5e 1gb connections to the same Dlink 10gb, 12x port switch.  I tested datastore creation on a 10gb connection a Thecuse N12000 NAS and a separate white box openfiler NAS, and in both situation, it's consistent, no issues with creating/accessing datastore with 1gb connection, but when using 10gb connection, everything works fine, up until completing the datastore process.  In either connections, 1 or 10gb connection, the initial connection testing is fine...Can ping via ip on the network or via the host vmkping utility.

This is the first go around with 10gb connection for me so perhaps I'm missing something?
