VSI error: "Expected at least 1 port when creating datastore PS01-TestVSI"

I have a PowerStore 500T direct-attached to a couple of R750 using NVMe-TCP. The PowerStore has been configured by the ProDeploy Team and looks working great.

Powerstore is updated to latest OS version (3.2.0.1) and our vCenter is a 7.0 U3g (20150588). I've deployed a VSI 10.1 virtual appliance, all looks fine from its dashboard, but when I attempt to create a new datastore:

1. The new datastore is created on the PowerStore.

2. The new datastore is mapped correctly to the vSphere cluster.

3. The ESXi can see the new volume.

4. The task fails with error: "Expected at least 1 port when creating datastore PS01-TestVSI" and doesn't create the vmfs datastore.

Have you any idea about this error?

Thank you and have a great day,
