3.5.1 Matrix Server Upgrade Guide

Appendix B: Install the SLES9 Operating System and Kernel 58

hostnames include the hostnames of all servers in the matrix and the

hostnames of all FibreChannel switches being used with the matrix.

One easy way to ensure reliable hostname lookups is to put all critical

hostnames and their IP addresses in /etc/hosts on each of the servers

(see the hosts(5) man page.) After you have done this, ensure that the

host lookup order in /etc/nsswitch.conf specifies that the hosts file will

be examined first (see the nsswitch.conf(5) man page). Other

mechanisms, apart from /etc/hosts, can also be used, depending on

your site network configuration.

• /etc/sysconfig/kernel file. If the following modules are present in the

INITRD_MODULES directive, remove them.

Matrix Server appends these 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.

6. Run mkinitrd If Necessary

If you edited the /etc/sysconfig/kernel file in the previous step, you will

need to run mkinitrd to create a new initrd image with the appropriate

drivers.
