HP Virtual Connect Enterprise Manager 7.0 User Guide

Tracking individual WWN addresses
Individual addresses in a WWN range (HP-predefined, VCEM-defined, or user-defined) can be
monitored by clicking on the Individual addresses secondary tab within the WWN Ranges List
page.
The following table lists and describes the WWN address status at Individual address page.
DescriptionItem
Address available to use in VCEM.Free
Address currently used by a server profile in VCEM.In use
Addresses used by server profiles in a VC Domain that has
been released back to Virtual Connect Manager and no
longer managed by VCEM.
External Address
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.
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.
Address management tasks
With VCEM 7.0 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 49 (page 106) and Figure 50 (page 106)
display MAC and WWN exclusion ranges.
