Reclaiming external WWN addresses
When a VC Domain containing server profiles is removed from a VC Domain Group configured
to use User-Defined WWN address ranges, VCEM reclassifies the WWN addresses in the removed
VC Domain as external. This does not change the actual addresses for server profiles in the VC
Domain. Addresses identified as external are reserved for VC Domains outside of VCEM and will
not be used by VCEM.
To change the status of an address from External to Free, use the Reclaim External button. Before
freeing an address, verify that the address is no longer used by a VC Domain outside of VCEM.

1. From the Virtual Connect Enterprise Manager home page, under the Administration heading,
click the World Wide Names hyperlink.
