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.

Modifying FC fabric properties

To modify the properties of an existing FC SAN fabric, use the set fabric command:

>set fabric name=MyNewName portspeed=4Gb

Each HP 4Gb VC-FC module can be connected to one external FC SAN fabric. All uplinks must be on the same fabric. Use this command to:

•Name the FC SAN fabric connected to each VC-FC module.

•Set the number of uplinks to be used (1, 2, or 4).

•Select the uplink port speed to be used on each VC-FC module.

The number of enabled uplinks and the number of servers in the enclosure determines the effective oversubscription for that FC connection. For additional information on Fibre Channel mapping, see the HP Virtual Connect for c-Class BladeSystem User Guide.

Displaying FC fabrics

To display a list of all FC SAN fabrics, use the show fabric command:

>show fabric

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.
