I'd suggest you work the request through QLogic tech-support, as the upstream qla2xxx driver has been stripped of all failover components. http://www.qlogic.com/support/report_problem.asp > We have a MSA1500 connected to two fabrics and 4 hosts connected to the > MSA1500, each with 2 Qlogic FC HBA's.
