HP Virtual Connect Enterprise Manager 6.1 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 the minimum
number of enclosures. The Ethernet uplinks define the minimum number of enclosures. The enclosure with a
defined Ethernet uplink port defines the minimum number of enclosures.
In this example, the minimum number of enclosures is two. The second enclosure is the last enclosure that
contains Ethernet uplink ports.
