MPIO Driver for IBM AIX 6.1 that supports EVA8xxx

I recently ran some switch maintenance on our DCX Backbone. I had to remove each EVA switch connection, one at a time, replace the 8Gb SFP with a 4 Gb SFP, then on to the next...we had a total of 8 connections per EVA8000, 4 per fabric. This was a work-around to address a bug with the Brocade 6.2.0e Fabric OS Version and the 8Gb SFP. (Specifically, 8Gb SFP drivers can misinterpret a failed read of data from an SFP to be valid data. When this occurs, the firmware misinterprets the invalid data that is read and believes that a transmit fault condition exists. In reaction to the the SFP firmware will temporarily drop the laser light and immediately bring the port back online.)

One one of our AIX V6.1 hosts, all of it's
EVA8000 Luns presented to the IBM AIX V6.1 host disappeared. The application hung, and the system was unavailble until the SysAdmin rescanned the fabric. Oh, by the way the host is using EMULEX HBA's. It appears that the MPIO driver did not failover the EVA Paths appropriately; which HP MPIO Driver would you recommend for an AIX V6.1 host with EMULEX HBA's.? With an emphasis on FREE!
