Boot over SAN

Boot over SAN

Boot over SAN configuration using the Basic Port Configuration dialog box is enabled on all

platforms if the HCM version is 1.1 or higher.

The Boot over SAN feature allows you to target remote boot devices (LUNs on SAN storage arrays)

from which to boot the host system. When the host’s operating system and adapter driver are

installed on the remote device, the adapter BIOS and user-configurable boot instructions stored in

adapter flash memory allow the host to boot from the device.

NOTE

Various operating systems require you to follow specific guidelines to enable servers to boot from a

SAN. Understanding these requirements is key to a successful deployment of a boot over SAN

environment.

Boot LUNs are identified to adapter ports using the BIOS Configuration Utility and BCU commands.

These utilities also allow you to enable or disable BIOS for booting the host system over SAN, set

boot options, and set the port speed. Refer to the Brocade Adapters Installation and Reference

Manual for instructions.

BIOS boot over SAN provides the ability for x86 and x86_64 systems to perform booting of the OS

installed on the SCSI disk connected over the Fibre Channel SAN.

The maximum number of supported adapters is limited to 16 and the maximum targets and LUNs

that are displayed during discovery is limited to 256.

After you have configured boot devices using the BIOS Configuration Utility, you can enable or

disable BIOS for Boot over SAN, set boot options, and set port speed using the HCM GUI. All

configuration information is stored in flash memory.

Configuring Boot over SAN

The boot-LUN table lists the vendor information, LUN capacity, and whether the LUNs are

accessible. These fields are not editable.

You can access the Boot-over-SAN dialog box by selecting the Host, an adapter or a physical port

from the device tree.

1. Select Configure > Basic Port Configuration from the Host Connectivity Manager.

The Basic Port Configuration dialog box displays.

2. Click the Boot-over-SAN tab.

The Boot-over-SAN dialog box, shown in Figure9, displays.
