10.2 System Configuration
The system must be manually configured to automatically load the device
drivers for the controllers to which the multipath IO devices are connected
within the INITRD. Therefore add the needed driver module
to the variable INITRD_MODULES in the file
/etc/sysconfig/kernel.
If your system, for example, contains a RAID controller accessed by the
cciss driver and multipath IO devices connected to a Qlogic controller
accessed by the driver qla2xxx, this entry would look
like:
INITRD_MODULES="cciss"
Because the Qlogic driver is not automatically loaded on start-up, add it
here:
INITRD_MODULES="cciss qla2xxx"
After having changed /etc/sysconfig/kernel,
recreate the INITRD on your system with the
command mkinitrd.
When you are using LILO as a boot manager,
reinstall it with the command /sbin/lilo. No further
action is required if you are using GRUB.
