WWN Addresses
NOTE: In VCEM 1.40 and later, a new “VCEM-defined” range has been reserved, from which
VCEM allocates WWN addresses. VCEM no longer uses the “HP pre-defined” range for WWN
address allocation. However, server profiles created before VCEM 1.40 will continue to use the
HP pre-defined addresses already assigned to them.
The WWN range used by the VCEM domain must be unique within the environment. HP provides
a set of predefined addresses that is reserved for VC and VCEM and does not conflict with server
factory-default WWNs.
Overall, WWN range management in VCEM is very similar to MAC ranges. VCEM allocates
WWNs automatically according to VC Domain Group configuration using HP-predefined,
VCEM-defined, or user-defined WWNs. You can use the HP-predefined range only to import server
profiles or server profiles created on previous versions of VCEM.
To access WWN addresses from the VCEM home page, click the World Wide Names hyperlink.
The WWN Ranges List page appears.
