Completing the Linux Multipath Setup

After a valid raidtab file is created in the /etc directory, verify that the correct drivers

and modules are loaded.

To verify properly loaded files:

1. Verify that the md and multipath drivers are loaded, either statically or by a

module load. Enter:

lsmod

This command reveals which modules are running. Examining the boot-time

messages reveals the static loaded drivers.

IMPORTANT: If you have made configuration changes to the kernel (including the

multipath or /dev/md driver) and have not rebooted from the new kernel, you must reboot

before continuing. Red Hat and SuSE typically include the md driver in the kernel.
