Additional Red Hat and SuSE Linux Preparations

IMPORTANT: For Red Hat and SuSE operating sytems, configure the system for multipath

before installing the software from the CD. For configuration instructions for UnitedLinux

operating systems, refer to Chapter 2, “Installation and Operation.”

Before installing Smart Array Multipath software on a server with a Red Hat or SuSE

Linux operating system, perform the following procedures:

• Always edit the active Linux kernel that enables the system to recognize the

multipath hardware configuration. Refer to “Editing the Active Linux Kernel” in

this chapter.

• Always modify the raidtab configuration file to be sure it contains the appropriate

information. Refer to “Modifying the RAIDTAB Configuration File” in this

chapter.

Editing the Active Linux Kernel

To configure the system for multipath operations:

1. Modify the makefile.

2. Overwrite the active config file.

3. Edit the make config and make the kernel.

4. Make and install the module.

The procedures in this section provide examples for all these basic steps.

Modifying the Makefile

IMPORTANT: The following procedure is for Red Hat Linux only.

To modify the Makefile:

1. Identify the name of the active kernel:

a. At the root level, enter:

uname –a

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 38 39
