been released back to VCM and no longer managed by
VCEM.

Addresses that reside in a VCEM Exclusion range list.
VCEM will not allocate any address that is marked as
excluded.
Excluded Addresses
Creating WWN exclusion ranges
VCEM requires that you define exclusion ranges for both MAC and WWN addresses if:
• VCEM and VC Domains outside of VCEM management are sharing the same user-defined
MAC and WWN ranges.
• VCEM is running in a federated CMS environment where multiple instances of the VCEM
application are operating on the same network.
NOTE: In the case of federated CMS environments, you can select from a pre-defined VCEM
WWN subrange during a new HP Insight Management DVD installation.
Exclusion ranges are used to set aside addresses that might be in use for other purposes within
your data center. Excluded address ranges are not assigned for use by VCEM.
1. From the VCEM home page, under the Administration heading, click the World Wide Names
hyperlink.
2. From the Select ranges to configure list, select WWN.
3. Select a WWN address range from the WWN Ranges list. The exclusion range must be
contained within the address range to which the exclusion range belongs.
4. Select the Exclusion ranges tab and choose from the list of ranges.
5. To create the exclusion range, click New.
IMPORTANT: External addresses that are included in a WWN exclusion range remain
external addresses. The status of an external address does not change if it is included in a
WWN exclusion range.
6. Manually enter the address range to exclude it.
Address management tasks
There is no longer a need to plan and create the exclusion ranges manually. The HP Insight
Management DVD installation automatically creates the necessary MAC and WWN exclusion
ranges in VCEM for subrange selection. Figure 87 (page 139) and Figure 88 (page 139) display
MAC and WWN exclusion ranges.
