No module qla2xxx_conf found for kernel 2.6.9-42.0.10.EL.

There are at least two different versions of the qla2xxx driver: one (the basic version) is included with the RHEL 4 kernels, another (a version with built-in multipath functionality) is available separately from QLogic and HP.

Looks like you've used the separately-packaged version.

You should install the kernel*-devel package that matches your new kernel version. Then you must recompile the driver so that it matches your new kernel (basically the same thing you did when originally installing the driver package). See the installation instructions of the driver.

This does not overwrite the driver for your old kernel: each kernel version has a separate module directory under /lib/modules.

you may do a copy some thing similar

â ¢ Copy the old /lib/modules/2.4.21-47.ELsmp/kernel/drivers/scsi/lpfcdd.o to the corresponding new kernel location(/lib/modules/2.4.21-53.ELsmp/kernel/drivers/scsi/lpfcdd.o)
