HP Virtual Connect Enterprise Manager 6.2 User Guide

3. Perform the following actions for each VC Domain that uses HP-predefined or user-defined
ranges that you want to remove from the VC Domain Group. Factory-default MAC, WWN,
and serial number ranges are released back to Virtual Connect Manager as Factory-default.
If factory-default MAC or WWN addresses or Serial Numbers are not being used, address
ranges must be specified for each removed VC Domain. These address ranges must be unique
and distinct to avoid assignment of duplicate addresses. Each selected MAC and WWN
address range must also be recorded as an exclusion range to prevent assignment by VCEM.
VCEM manages a proprietary Serial Number range so you do not need to define an external
range for serial number.
The selected HP-predefined ranges are identified as user-defined ranges by Virtual Connect
Manager after the VC Domain is removed from VCEM.
a. Enter the MAC address range. To use an HP-predefined MAC range, from the MAC
Range section, select the Use HP Pre-Defined range box, and then select a range from
the list. You can also clear the Use HP Pre-Defined range box and then enter the start
and end addresses for the MAC range. Valid MAC address range is
NN-NN-NN-NN-NN-NN where N is a hexadecimal digit (0-F) and cannot exceed 12
characters. The VC Domain configuration applies this MAC address range after being
removed from VCEM control.
b. Enter the WWN address range. To use an HP-predefined WWN range, from the WWN
Range section, select the Use HP Pre-Defined range box, and then select a range from
the list. You can also unselect the Use HP Pre-Defined range box and then enter the start
and end addresses for the WWN range. Valid WWN address range is
NN:NN:NN:NN:NN:NN:NN:NN where N is a hexadecimal digit (0-F) and cannot
exceed 16 characters. The VC Domain configuration applies this WWN address range
after being removed from VCEM control.
c. Enter the Serial Number range. To use an HP-predefined Serial Number range, from the
Serial Number Range section, select the Use HP Pre-Defined range box, and then select
a range form the list. You can also unselect the User range box and then enter the start
and end values for the Serial Number Range. Valid Serial Number range is
VXC01NNNNN for User-defined or VCXNNNNNNN for HP-predefined, where N is a
hexadecimal digit (0-F) and cannot exceed 10 characters. The VC Domain configuration
applies this Serial Number address range after being removed from VCEM control.

Working with multienclosure VC Domains
VCEM supports multienclosure VC Domains. A multienclosure VC Domain is a VC Domain with
one local enclosure and up to three remote enclosures. VCEM supports VC Domains with up to
four BladeSystem c7000 enclosures.
Within each enclosure of a multienclosure domain, the Virtual Connect Ethernet Modules must
follow the same configuration rules as VC Domains with single enclosures. However, each enclosure
within the VC Domain might have a different configuration of Ethernet modules. Stacking links must
enable Ethernet packets to reach all Ethernet modules within the VC Domain. All enclosures in a
multienclosure VC Domain must have the same Virtual Connect Fibre Channel Module configuration.
The following figure illustrates a valid configuration of Ethernet and Fibre Channel Virtual Connect
modules in a VC Domain with multiple enclosures. The black lines linking the Ethernet modules
illustrate the stacking links.
VCEM supports VC Domain Groups containing VC Domains with multiple enclosures, and enables
the VC Domains to contain different numbers of enclosures, as long as each VC Domain contains
