NOTE: Creating exclusion ranges is optional but highly recommended to avoid MAC/WWN
address conflicts in the same network.
HP recommends using exclusion ranges in the following scenarios:
• When VC Domains are not VCEM controlled and are using other user-defined MAC or
WWN addresses that overlap with VCEM user-defined MAC or WWN ranges. For
example:
VCEM exclusion ranges need to be created for MAC or WWN addresses used by other
VC Domains.
• When installing multiple instances of VCEM in the same network. For example:
Exclusion ranges need to be created for VCEM-defined MAC and WWN addresses.
7. (Optional) Use the following procedure to configure the WWN ranges to meet your
requirements.
NOTE: It is optional to set up a user-defined range in VCEM. This is only required if you are
managing VC Domains which use special user-defined WWNs.
a. Click Home from the VCEM home page. To return to the home page in a stand-alone
VCEM installation, click the Home link on the upper right-hand corner of the window.
b. Click the World Wide Names hyperlink.
c. To create a custom range, click Add custom.
The WWN range used by the VCEM Domain must be unique within the environment. HP
provides a set of predefined ranges that are reserved for use by VC and VCEM, and
does not conflict with server factory-default WWNs.
When using the HP-predefined WWN ranges, ensure that each range is used only once
within the environment.
For more information, see “Adding a custom WWN address range” (page 144).
8. (Optional) Create WWN exclusion ranges. For more information, see “Creating WWN
exclusion ranges” (page 138).

9. Click the VC Domains tab. VC Domains appear as the following:
• Unconfigured VC Domains—Appear as VCD_name, where name is the temporary name
automatically given to the VC Domain.
• Configured VC Domains—Appear with the VC Domain name.
10. Select a VC Domain, and then click License to license the domain. For more information on
licensing, see “VCEM licensing” (page 42).
