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 is operating on the same network. See
“Creating VCEM exclusion ranges for a
federated-CMS environment” (page 104) for more information.
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.
IMPORTANT: After upgrading to VCEM 1.4x or later, HP recommends that you delete any
exclusion ranges for HP predefined MAC and WWN addresses.
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.
Creating VCEM exclusion ranges for a federated-CMS environment
VCEM requires unique MAC and WWN address ranges for operation. In a federated-CMS
environment, VCEM needs to define as many MAC and WWN exclusion ranges as necessary to
avoid address conflicts with MAC and WWN addresses in use by other VCEM instances.
When installing VCEM in a federated-CMS environment it will be necessary to:
