Maybe I've not well explained using my smartphone to write. I know how the connections must be made, this is not my first FMC. My question is related to this one using at the same time existing DS14MK4FC shelves and a new set of SAS ones bridged to FC switches using the Atto.
In this way on the switch some zoning must be made and at the end we will have zone for FC loops and controller initiators and zone for FC datapath coming from SAS and the same initiators. Suppose that you have an FC disk loop coming to port 7 and the 4 HBA initiators fm NetApp controllers on a side of the MC we will have:
zonecreate "STOR_1_8", "1,1; 1,2; 3,1; 3,2; 1,7" zonecreate "STOR_3_8", "1,1; 1,2; 3,1; 3,2; 3,7"
now we plug the fibers coming fm the two Atto on port 8 on each switch, so:
zonecreate "STOR_1_8", "1,1; 1,2; 3,1; 3,2; 1,8" zonecreate "STOR_3_8", "1,1; 1,2; 3,1; 3,2; 3,8"
In this way the initiator ports on ports 1 and 2 we'll receive traffic at 4 Gbps from the FC shelves and traffic at 8 Gbps from Atto...
With this configurazion our 8040 crashed after few minutes from Atto insertion with a lot of messages like this:

Hi everybody
Hi,
Can fc path coming fm atto bridges share the same iinitiators on the fas used also by the fc disk loop?
Following an head swap fm 3160 to 8040 with 8.2.1 I've zoned a store zone with the fc port used by atto and the 4 initiators on 8040. Exactly as done with port coming from fc loops
The fas starts to message a lot of timeouts and errors related to the sas disks then panic
In an FMC, all shelves are attached via an FC-switch, right? I expect the ATTO-brides are attached like a disk shelf, so connected to the switch, not to the head. We're going to do that in July / August.
