[Openstack] iSCSI multipath


Hi everyone,

I'm using delliscsi driver as cinder backend in a new queens cluster.

Checking all nodes connections to storage layer, I figured out that 
after discovering and logging in (successfully) on every path, all nodes 
set up only 4 paths on 8 totals.

Multipath on these 4 paths is working well and Im not experiencing any 
issue, I just wonder why only 4 paths are used... am I ignoring some 
configuration or default behaviour?

Thanks in advance

Ramon
