You can configure the root partition with DM-Multipath on your SUSE Linux Enterprise Server host.
Steps
- Configure DM-Multipath support.
- Install the Linux Host Utilities.
- Enable all paths to the LUN on the storage controller.
- Re-create the initrd by running the following command:
| If you are using... |
Enter the following command... |
|---|
| SUSE Linux Enterprise Server 11 |
mkinitrd -f multipath |
| SUSE Linux Enterprise Server 10 SP2 |
mkinitrd -f mpath |
Note: You must keep a backup of the initrd image.
- Reboot the host.
Note: Because all paths to the SAN boot LUN are now available on the host, you should configure all paths in the HBA boot BIOS as primary boot device, secondary boot device, and so on.
