I have several Sun X4100 systems (X86_64) running RHEL 4 update 4, with kernel 2.6.9-42.0.2.ELsmp. These systems each have two QLogic QLA200-E Fibre Channel HBAs installed. I am using the driver kernel module that comes with the kernel RPM.

From everything that I've been able to read, the default behavior of the the driver is to have "failover" enabled. Further, I should be able to force this behavior by setting the option "pts=1 ql2xfailover=1".

Unfortunately, this isn't working. modinfo on the qla2xxx driver does not show the ql2xfailover as an available parameter.

This is the version of the module I have:

filename: /lib/modules/2.6.9-42.0.2.ELsmp/kernel/drivers/scsi/qla2xxx/qla2xxx.ko
version: 8.01.04-d7 1036BB22AA28C8D7180B7E1

Am I doing something wrong, or has failover support been disabled in this module for some reason?

Thanks,
