10. If there is more than one boot port available, repeat this step until all boot ports for this adapter are
added. In this example, there is one boot port for each HBA.
11. Save the changes.
12. On the Fast!UTIL main menu, select the next HBA port, repeat the above steps to add the boot ports,

Single Path temporarily until after the Windows Server OS is loaded and the MPIO feature is
installed.
15. Modify the boot order in the host server BIOS or system setup (if required).
Physical host servers with an internal RAID controller and local disks may be configured to boot

server from attempting to boot from a local disk if the SAN becomes unavailable. Some hosts will
automatically detect available boot devices and will dynamically change the boot order from SAN to
local disk if the SAN is temporarily unavailable. Manually changing the boot order in the host server
BIOS from local disk back to SAN may be required after the SAN becomes available again. The
