•
MAC or WWN addresses or serial numbers that are assigned to a profile must not be in use by VCEM
or in a VCEM exclusion list. If the MAC or WWN addresses or serial numbers are user-defined, then
you must define an address range in VCEM.
•
If the VC Domain contains server profiles, the MAC addresses, WWNs, and serial numbers allocated
must be compatible with the MAC, WWN, and serial number range types of the VC Domain Group:
•
A VC Domain containing server profiles with factory-default addresses can be added to a VC
Domain Group with VCEM-defined range types, and user-defined range types. To add a VC
Domain to a VC Domain Group with factory-default range types, all profiles of the VC Domain
must be configured with factory-default addresses.
NOTE: After upgrading from VCEM 1.20 or 1.3x to VCEM 6.0, VC Domain Groups that were
using HP-predefined ranges for MAC and WWN addresses will start using VCEM-defined ranges
for new server profiles. VCEM 6.0 and later do not use HP-predefined ranges for MAC and WWN
addresses.
•
A VC Domain containing server profiles with addresses allocated as user-defined range type can
be added to a VC Domain Group with a user-defined orVCEM-predefined range type. A
user-defined (custom) MAC and WWN range that includes all addresses allocated to server profiles
within the VC Domain must be defined in VCEM before adding the domain to the VC Domain
Group.
•
A VC Domain containing server profiles with addresses allocated as HP-predefined range type
can be added to a VC Domain Group with an VCEM-predefined or a user-defined range type.
•
An unconfigured VC Domain without server profiles has no range type restrictions when adding
in a VC Domain to a VC Domain Group.
The following table summarizes MAC address, WWN address, and serial number range type compatibility
when adding a VC Domain to a VC Domain Group.

VC Domain configuration must be identical to the VC Domain Group configuration. Verify that the following
items are identical:
•
Interconnect bays location and model
•
Enclosure model
•
Domain settings:
Configuration for double density servers (for example, BL2x220c)
•
•
Configuration for full-height and half-height single density servers (for example, BL460c, BL480c)
•
Ethernet settings:
MAC Cache Failover:
•
•
Enable Fast MAC Cache Failover
•
MAC Refresh Interval
•
IGMP Snooping:
Enable IGMP Snooping
•
•
