HP Virtual Connect for c-Class BladeSystem Version 3.00 Setup and Installation Guide for HP Integrity BL8x0c i2 Series Server Blades

HP Virtual Connect Manager 92
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.
