Hi Luke, We've been using MPXIO (STMS) with ZFS quite solidly for the past few months. Failover is instantaneous when a write operations occurs after a path is pulled. Our environment is similar to yours, dual-FC ports on the host, and 4 FC ports on the storage (2 per controller). Depending on your gear using MPXIO is ridiculously simple. For us it was as simple as enabling it on our T2000, the Opteron boxes just came up.

Hi, I am running Solaris 10 ZFS and I do not have STMS multipathing enables. I have dual FC connections to storage using two ports on an Emulex HBA. In the Solaris ZFS admin guide. It says that a ZFS file system monitors disks by their path and their device ID. If a disk is switched between controllers, ZFS will be able to pick up the disk on a secondary controller. I tested this theory by creating a zpool on the first controller and then I pulled the cable on the back of the server. the server took about 3-5 minutes to failover. But it did fail over!! My question is, can ZFS be configured to detect path changes quicker? I would like to configure ZFS to failover within a reasonable amount of time, like 1-2 seconds vs. 1-5 minutes.
