3.5.1 Matrix Server Upgrade Guide

Appendix A: Install the RHEL4 Operating System 48

To avoid this problem, you will need to modify the mount command

specified in the script to enable the root filesystem to be remounted

via its device path. Locate the following line in the /etc/init.d/halt script:

mount | awk '{ print $3 }' | while read line; do

On this line, change $3 to $1.

mount | awk '{ print $1 }' | while read line; do

• /etc/modprobe.conf file. Depending on your configuration, you may

need to modify this file:

– If you will be using a third-party MPIO solution or booting from

the SAN and want the HBA driver to be loaded during the initial

booting of the kernel, consult your vendor documentation for any

changes needed to this file.

– If you want Matrix Server to load the HBA driver, you may need to

modify the /etc/modprobe.conf file. In the file, look for entries such as

the following for scsi_hostadapter.

alias scsi_hostadapter qla2x00

alias scsi_hostadapter1 aic7xxx

alias scsi_hostadapter2 ...

NOTE:

Skip this step if the file has the following entry:

alias scsi_hostadapter off

Remove the scsi_hostadapter entry for QLogic or Emulex drivers,

or comment them out with a “#” symbol. Then, if there are

additional entries for the scsi_hostadapter, renumber the entries.

(The first scsi_hostadapter entry is not numbered, the second entry

is scsi_hostadapter1, the third entry is scsi_hostadapter2, and so

on.) In this example, the edited file will look like this:

alias scsi_hostadapter aic7xxx

alias scsi_hostadapter1 ...

Matrix Server appends the removed modules to the /etc/hotplug/

blacklist file, which specifies modules that should not be automatically

loaded by the kernel. This creates a controlled environment for Matrix

Server at boot time, allowing it to load its own modules. If this
