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.
Assigned WWNs
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 do 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.
