Emulex OneCommand Manager Application User Manual (P006979-01A Version 5.2, August 2011)

The OneCommand Manager User Manual Page 160
The configuration regions on the adapter store the configuration data for each of these boot types.
Boot Device Parameters
The boot LUN for all three boot types is in the range of 0-255. EFIBoot and OpenBoot (FCode) also
support an 8-byte LUN, which you can use instead of the single-byte LUN. You must select which LUN
type to configure.
• For OpenBoot, you must also provide a Target ID parameter.
• The OneCommand Manager application runs on a running OS, so you must boot the host to
configure boot from SAN with the OneCommand Manager application.
• You must work from a running host that supports the OneCommand Manager application. Often,
this host has booted from a direct-attached drive. With the OneCommand Manager application,
you can configure a direct boot host to boot from a SAN. You can modify an existing boot from
SAN configuration or configure boot from SAN on an adapter for installation in another host so it
can boot from SAN.
• You must know what boot code type the adapter has; the OneCommand Manager application
cannot detect this. Without knowing this, you could configure a boot type but not be able to boot
from it since the adapter lacks the correct boot code.
• You must know what boot code type the system supports; the OneCommand Manager
application cannot detect this. You can configure any boot type, but if the system does not
support that type, it cannot boot from SAN.
• If you manage adapters on a remote host that is running a version of the OneCommand
Manager application that does not support boot from SAN, the Configure Boot button does not
appear.
• One of the following FC or FCoE adapter drivers must be installed:
• Storport Miniport or UCNA driver for Windows
• Emulex driver for Linux
• Solaris emlxs FCA Driver
• VMware ESX 4.0 or 4.1
To configure boot from SAN:
1. Select Host or Fabric view.
2. In the discovery-tree, click the FC or FCoE adapter port on which you want to enable boot from
SAN.
Note: x86 and OpenBoot share the same configuration memory space. You cannot
configure an adapter for both x86 and OpenBoot at the same time. If you try, a
message appears that the existing boot type configuration will be overwritten by the
new configuration.
Note: Boot from SAN configuration does not affect current system operation. The changes
only take effect upon reboot if you have configured it correctly.
Note: You can configure boot from SAN before boot by using the Emulex Boot BIOS setup
command line interface that runs during system startup. See the Emulex Boot BIOS
setup program documentation for details.
