Hi, I solved it using the patch for hardware handler rdac from RHEL5.1 BETA and rebuild kernel from RHEL5.0 Stable with that patch. I also had to use device-multipath-tools from RHEL5.1 Beta and it's working fine. If one path to the controller fails, it keeps on the same controller as it has one active path.
When both active paths fail, it requests through the passive path the failover of the lun and both passive paths transform in active ones.
