During Red Hat Linux installation, the incorrect driver is installed for the Sun StorageTek 4Gb FC Dual-Port Express Module (EM). Consequently the hardware prober kudzu never loads the correct driver for this EM. The following problems occur:
The qla2322
driver loads instead of the qla2400
driver. The qla2322
driver prevents the use of any
Fibre drives attached to the I/O card during installation.
The following incorrect entry is entered in /etc/modprobe.conf
and is included in the kernel’s initial ramdisk.
/etc/modprobe.conf
After the installation is complete, the following lines are incorrect in /usr/share/hwdata/pcitable
and cause kudzu to assign incorrect drivers
on the installed system:
0x1077 0x2422 "qla2322" "QLogic Corp.|QLA2422 Fibre Channel Adapter" 0x1077 0x2432 "qla2322" "QLogic Corp.|QLA2432 Fibre Channel Adapter"
During the installation, the following lines are incorrect in /modules/pcitable
and cause kudzu to assign incorrect drivers on the installed
system:
0x1077 0x2422 "qla2322" "QLogic Corp.|QLA2422 Fibre Channel Adapter" 0x1077 0x2432 "qla2322" "QLogic Corp.|QLA2432 Fibre Channel Adapter"
The following output shows the incorrect driver assigned to the I/O card by kudzu:
class: SCSI bus: PCI detached: 0 driver: qla2322 desc: "QLogic Corp. QLA2432 Fibre Channel Adapter" vendorId: 1077 deviceId: 2432 subVendorId: 1077 subDeviceId: 013d pciType: 1 pcidom: 0 pcibus: 83 pcidev: 0 pcifn: 1 - class: SCSI bus: PCI detached: 0 driver: qla2322 desc: "QLogic Corp. QLA2432 Fibre Channel Adapter" vendorId: 1077 deviceId: 2432 subVendorId: 1077 subDeviceId: 013d pciType: 1 pcidom: 0 pcibus: 83 pcidev: 0 pcifn: 0
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.
