AIX multipath driver

I know that this is slightly off topic, but I'm wondering if anyone knows of
any company that makes a driver similar to Veritas' DMP driver for AIX? It
could be open sourced or proprietary.
If your not familiar with DMP, it allows a system with multiple host bus
adapters talk to storage with multiple ports. It allows load balancing
across the HBAs when the HBAs are both active. Then if there is a path
failure, the driver is able to reroute I/Os through the second HBA.
I looked through the archives and saw references to "REACT" and "ATF", does
anyone know if they still exist? Are there any others? I would be
interested in drivers that use the second HBA as just a redundant path
(ie. no load balancing) as well.
Any info would be appreciated.
