(FC) Setting up a SAN boot LUN on SUSE Linux Enterprise Server

You can set up a SAN boot LUN to work in a SUSE Linux Enterprise Server environment that is using the FC protocol.

1. Create a LUN on the storage system and map it to the host. This LUN will be the SAN boot LUN.
   You should ensure the following:

   • The SAN boot LUN is mapped to the host.
     Note: If you are running a SAN boot installation using a version of SUSE Linux Enterprise Server prior to 11 SP2, then only one primary path to the LUN is available. SUSE Linux Enterprise Server 11 SP2 supports multiple paths to the LUN.
   • The LUN is visible to the host during the boot process.
2. Enable the BIOS of the HBA port to which the SAN boot LUN is mapped.

   For information about how to enable the HBA BIOS, see your HBA documentation.

3. Install the operating system on the SAN boot LUN.
4. Install the Host Utilities.
5. Configure DM-Multipath.
