Last week I was configuring some new vSphere 5.1 (Enterprise) hosts in a dedicated cluster and created some VMFS 5.58 datastores at the Dell Eq. PS6000 SAN with latest firmware, after configuring SIOC I received this error message:
The datastore is connected to one or more pre-4.1 hosts that do not support Storage I/O Control.
That’s weird, I’ve reinstalled all hosts (not updated) and created new datastores, there are no vSphere 4.1 hosts in this cluster (even connected to the datastore) and the PS6000 supports SIOC..
Not really a solution.. but you can only configure SIOC with the Enterprise Plus license.. crap!
