Symmetrix Fibre Channel with Qlogic HBAs on Linux Hosts

Arbitrated Loop Configurations

5. Compile the kernel:

make dep

make clean

make install

make modules

make modules_install

cd /boot

6. Build a ramdisk image:

mkinitrd /boot/initrd-$1.img $1

(where $1 is the kernel version)

For example:

mkinitrd /boot/initrd-2.2.17.img 2.2.17

The mkinitrd command is used to create a new ramdisk image and is

dependent upon the loopback device being available. If the loopback

driver is selected in the kernel as a module, ensure that it is loaded with

#lsmod. If the loopback driver was not loaded, insert it with #insmod

loop.

7. Run lilo to update the loading map and reboot:

lilo -v

reboot

Kernel Upgrade For a kernel upgrade, install Linux from the Red Hat v6.2 CD,

following the procedure in the installation guide. Partition the boot

drive and select the packages and services necessary for the host. The

host can be upgraded from Red Hat v6.2 or Red Hat v7.0 to up to

v2.2.17 of the Linux kernel.

To upgrade the host to a newer version of the kernel, the kernel must

be downloaded, from: http://www.kernel.org/mirrors/.

1. Prepare the host for the new version of the kernel:

cd /usr/src

rm -f linux

2. Untar the kernel and create a directory for it:

tar zxvf linux-$1.tar.gz

mv linux linux-$1

ln -s linux-$1 linux

cd linux

(where $1 is the kernel version)
