Creating MAC 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
MAC 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 MAC addresses
hyperlink.
2. From the Select ranges to configure list, select MAC.
3. Select a MAC address range from the MAC ranges list. You can also look at Range Usage
to determine the percentage of free exclusion ranges. 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 MAC exclusion range remain external
addresses. The status of an external address does not change if it is included in a MAC
exclusion range.
6. Manually enter the address range to exclude it.
Deleting MAC exclusion ranges
1. From the VCEM home page, under the Administration heading, click the MAC addresses
hyperlink.
2. From the Select ranges to configure list, select MAC.
3. Select a MAC address range. 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 a MAC exclusion range.
5. Click Delete. You are prompted to confirm your choice.
6. Click OK.
IMPORTANT: If the exclusion range includes external addresses, these external addresses remain
external, even if the exclusion range is removed.
Before deleting the exclusion range, ensure all addresses within this range are not being used by
any other VC Domain or VCEM instance on your network.
Reclaiming external MAC addresses
External MAC addresses are generated when a VC Domain containing server profiles is removed
from a VC Domain Group configured to use user-defined MAC address ranges. Since every server
profile contains one or more MAC 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.
