The Red Hat Enterprise Linux Advanced Server 4 Update 4 (RHEL AS 4-U4) media loads and installs the incorrect driver for the Sun StorageTek 4Gb Fibre Channel Dual-Port ExpressModule. Consequently, the hardware prober kudzu never loads the correct driver for the Sun StorageTek 4Gb Fibre Channel Dual-Port ExpressModule. (CR 6463165)
During the installation of RHEL AS 4-U4 (2.6.9-42.EL kernels), kudzu probes the system for a Sun QLA2432 FC EM I/O card and loads the incorrect driver.
At the time of the Red Hat Linux installation, perform these steps:
Use a Kickstart file for installation. Add a device command to the Kickstart file "device scsi qla2400".
On the installed system, run the up2date application to get the latest updates from Red Hat.
Edit the file /etc/modprobe.conf:
Find "qla2322" in the last field on any alias scsi_hostadapter lines.
Replace "qla2322" with "qla2400".
Example:
alias scsi_hostadapter1 qla2322
becomes
alias scsi_hostadapter1 qla2400
Save the file and backup your existing initial ramdisk.
Create a new initial ramdisk that will include the qla2400 module.
Example:
mkinitrd -vf /boot/initrd-2.6.9-42.ELsmp.img 2.6.9-42.ELsmp
Reboot and verify that the new image boots and loads the qla2400 driver.
