3. Select a WWN address range. The exclusion range must be contained within the address range to
which the exclusion range belongs. Valid WWN ranges cannot contain all 0s or all Fs and cannot have
an F within either of the first two octets.
4. Click the Exclusion ranges tab.
5. To create the exclusion range, click New.
Reclaiming external WWN addresses
External WWN addresses are generated when a VC Domain containing server profiles is removed from a
VC Domain Group. Because every profile contains one or more WWN addresses associated with it, VCEM
identifies these addresses as external. 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.
To reclaim WWN addresses:
1. From the Virtual Connect Enterprise Manager home page, under the Administration heading, click the
World Wide Names
hyperlink.
2. From the Select ranges to configure link, select WWN. The WWN Ranges List page appears.
3. Select a WWN address range.
4. Click the Individual addresses tab.
5. From the Filter link, select External.
6. Select the external addresses.
7. Click Reclaim External. You are prompted to confirm your choices.
8. Click OK.
Adding custom WWN address ranges
Because the maximum range size is 131,072, a large range might take a few minutes to create. You can
create one custom range.
