Pre-installation configuration for Red Hat Enterprise Linux
2.1
Before installing Smart Array Multipath software on a server with a Linux Red Hat operating system:
Create a new Linux kernel that recognizes the multipath hardware configuration.
Modify the raidtab configuration file to be sure it contains the appropriate information.

Editing the active kernel

To configure the system for multipath operations, HP recommends the following steps:
Modify the makefile.
1.
Overwrite the active config file.
2.
Edit the .config and make the kernel.
3.
Insert the new kernel into the GRUB or LILO boot-loader.
4.
The procedures in this section provide examples for all these basic steps.
Alternatively, you can install the modules without rebuilding the kernel.
IMPORTANT: Modules not installed in a kernel are not loaded at boot time, requiring you to remake
modules after every power cycle or reboot. HP recommends that you install the modules into the kernel using
the steps in this section.
Modifying the Makefile
IMPORTANT: The following procedure is for Linux Red Hat only.
To modify the Makefile:
Identify the name of the active kernel:
1.
At the root level of the kernel source tree (usually /usr/src/linux-xxx), enter:
a.
uname -a
Remember this name for use in later procedures.
b.
Use an editor to modify the Makefile. For example, enter:
2.
vi Makefile
