Using the Brocade BIOS Configuration Utility
You can configure values of 1, 2, 5, and 10 minutes. This adds a delay in
discovering the boot LUN to help compensate for the time it takes storage
systems to boot up. During storage system boot, boot LUNs are not visible
to servers that are also booting up.
Set Loop if the port is connecting to storage in a Fibre Channel Arbitrated
Loop (FC-AL) and P2P if the port is connecting to storage in a
point-to-point topology.
Enable or disable LUN masking. LUN masking establishes access control
to shared storage to isolate traffic between different initiators that are zoned
in with the same storage target. For more information on LUN masking,
refer to the LUN Masking paragraph under
page 5.
