HP Virtual Connect 1.10Gb-F Ethernet Module for c-Class BladeSystem - Manual (Page 80)

Configuring the Virtual Connect domain using the CLI 80
accessing the physical FC HBA through the enclosure Onboard Administrator and the iLO interfaces on
the individual server blades.
When assigning WWNs to a FC HBA port, Virtual Connect will assign both a port WWN and a node
WWN. Because the port WWN is typically used for configuring fabric zoning, it is the WWN displayed
throughout the Virtual Connect user interface. The assigned node WWN is always the same as the port
WWN incremented by one.
Configuring Virtual Connect to assign WWNs in server blades maintains a consistent storage identity
(WWN) even when the underlying server hardware is changed. This method allows server blades to be
replaced without affecting the external Fibre Channel SAN administration.
CAUTION: To avoid storage networking issues and potential loss of data associated with
duplicate WWNs on a FC SAN fabric, plan carefully when allowing Virtual Connect to assign
server blade WWNs so that the configured range of WWNs is used only once within the
environment.
The WWN range used by the Virtual Connect domain must be unique within the environment. HP
provides a set of pre-defined ranges that are reserved for use by Virtual Connect and will not conflict with
server factory default WWNs.
When using the HP-defined WWN ranges, be sure that each range is used only once within the
environment.

Server Profile setup
A Virtual Connect server profile is a logical grouping of attributes related to server connectivity that can
be assigned to a server blade. With the Virtual Connect v1.10 and higher, the server profile can include
MAC address, PXE, and network connection settings for each server NIC port and WWN, SAN fabric
connection, and SAN boot parameter settings for each Fibre Channel HBA port. After being defined, the
server profile can be assigned to any server blade within the Virtual Connect domain. A Virtual Connect
domain can have a maximum of 64 Virtual Connect server profiles.
Virtual Connect provides the ability to configure PXE settings when using either VC Assigned or factory
default MAC addresses. In addition, Use BIOS is a new option for PXE, which maintains the current
settings as configured by RBSU.
Virtual Connect also provides the ability to override the Virtual Connect assigned MACs and/or WWNs
when creating a new profile.
When a server profile is assigned to a server blade, the Virtual Connect Manager securely connects to the
server blade, configures the NIC ports with the appropriate MAC addresses and PXE settings, and
configures the FC HBA ports with the appropriate WWNs and SAN boot settings. In addition, the Virtual
Connect Manager automatically connects the server blade Ethernet 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.
The Virtual Connect Manager 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-
