The 3590 is a dual ported device. It actually has two fiber port WWPNs. AIX actually is talking to both ports all the time but only sends out primary IO right now to whichever is the current primary. What is coming is load balancing based on what I know. This way the ES-1000s will have balanced IO if both ports are connected to 2 different pathways (ES-1000s). Finally, there is a reason 3590 is far superior.

I have (8) 3580 LTO drives FC-AL attached. I have (2) McData ES-1000 switches with 4 drives on each switch. The library control path is currently through DRIVE 1. I am actually looking for failover of the Library (/dev/smc0), in case of failure of drive 1 or the McData switch it's on. I can configure a second control path (in fact I have done this on drive 5 and it comes up on AIX as /dev/smc1, but I am not using it). As I read the readme on Atape it seemed the auto failover was what would handle this, but it says only for 3590 devices. The library has hot swap drives, but if drive1 failed or needs to be replaced I have some amount of downtime that I wouldn't have with the other drives.

Anybody know when it will be supported on 3584 library with Fibre Channel? Or is someone using it that way now?
