3.1.2 Matrix Server Upgrade Guide

Appendix A: Install the RHEL4 Operating System and Kernel 65

– 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

behavior is not desired, the blacklist file can be edited; however, doing

this is not recommended.
