HP Virtual Connect Manager Command Line Interface for c-Class BladeSystem Version 3.70/3.75 User Guide

Configuring the Virtual Connect domain using the CLI 148
• For FCoE connections, VC provides the ability to assign VC-assigned WWN and MAC addresses and
configure Fibre Channel boot settings and bandwidth. This protocol is only available on FlexFabric
server connections.
• For FC connections, VC provides the ability to assign VC-assigned WWN addresses and configure
Fibre Channel boot settings.
IMPORTANT: The term server blade also applies to HP Integrity multi-blade servers. For more
information on multi-blade servers, see the HP Virtual Connect Manager for c-Class BladeSystem
User Guide.
When a server profile is assigned to a server blade, VCM configures the connections with the appropriate
MAC/WWN addresses and boot settings. USE BIOS is an option for all connection boot settings that
preserves the options set in the RBSU or through other configuration utilities. Virtual Connect Manager
automatically connects the server blade Ethernet, iSCSI, FCoE, and Fibre Channel ports to the specified
networks and SAN fabrics. This server profile can then be re-assigned to another server blade as needed,
while maintaining the server's network and SAN identity and connectivity.
VCM can be configured so that server blades use server factory default MACs/WWNs or Virtual
Connect-administered MACs/WWNs. These administered values override the default MAC addresses and
WWNs when a server profile is assigned to a server, and appear to pre-boot environments and the host
operating system software as the hardware addresses. To use administered MAC/WWN addresses, select
a range of HP pre-defined or user-specified MAC addresses.
Review the following list of guidelines before creating and deploying server profiles:
IMPORTANT: Before assigning a profile, unassigning a profile, or modifying a profile, be sure to
review the "Server blade power on and power off guidelines (on page 153)."
• The server blade firmware and option card firmware must be at a revision that supports Virtual Connect
profile assignment. See the HP website (http://www.hp.com/go/bladesystemupdates).
• Before creating the first server profile:
o Select whether to use assigned serial numbers or factory default serial numbers.
o Select whether to use movable, administered MAC addresses and WWNs, or the local server blade
factory default MAC addresses and WWNs.
• After an enclosure is imported into a Virtual Connect domain, server blades are isolated from the
networks and SAN fabrics until a server profile is created and assigned.
• Server blades must be powered off to receive or relinquish a server profile assignment when using
Virtual Connect-administered MAC addresses or WWNs, or when changing Fibre Channel boot
parameters. When using Flex-10 or FlexFabric modules, there are special considerations for server
power.
• When assigning a VC-assigned serial number, the server must be powered off.
• FC SAN connections appear in server profile screens only when an HP Virtual Connect Fibre Channel
module is in the enclosure managed by Virtual Connect. FC SAN connections are added in pairs and
cannot be deleted. If an HP Virtual Connect Fibre Channel module is added to a Virtual Connect
domain with existing profiles, an option to add FC connections appears when editing existing profiles.
• FCoE connections appear in server profile screens only when an HP VC Flex Fabric 10Gb/24-port
Module is in the enclosure managed by Virtual Connect. FCoE SAN connections are added in pairs. If
an HP VC Flex Fabric 10Gb/24-port Module is added to a Virtual Connect domain with existing
profiles, you can add FCoE connections.
