Domain management
Domain overview
A Virtual Connect domain currently includes a single HP c-Class BladeSystem c7000 Enclosure for a total
of 16 servers (or up to 32 servers if the double-dense option is enabled), or a single HP c-Class
BladeSystem c3000 Enclosure for a total of 8 servers (or up to 16 servers if the double-dense option is
enabled). Within the domain, any server blade can access any LAN or SAN connected to a VC module,
and a server blade can be used as a spare for any server blade within the same enclosure.
By stacking (cabling) the Ethernet modules within the domain and connecting the FC modules to the same
set of FC SAN(s), every server blade in the domain can be configured to access any external network
connection. With this configuration, the Virtual Connect Manager can deploy and migrate a server blade
profile to any server in the Virtual Connect domain without the need to change external LAN or SAN
configurations.
Enclosure serial numbers
The enclosure serial number is used by the Virtual Connect Manager to associate a Virtual Connect
domain with a particular enclosure. The enclosure serial number can be altered for maintenance
purposes, such as when replacing the enclosure midplane. For more information, see SET ENCLOSURE
SERIAL_NUMBER in the HP BladeSystem Onboard Administrator Command Line Interface User Guide.
Enclosure serial numbers are unique as shipped from the factory, and must remain unique for proper
Virtual Connect Manager operation. Use care when altering the enclosure serial number to ensure that
serial numbers are unique within the management network.
Domain Settings (Domain Configuration) screen
Use this screen to change the domain name or delete a domain.
The Remove from Domain feature (also known as administrative removal) enables users to remove an
interconnect module from the Virtual Connect domain without having to delete the entire domain, or
having the bay permanently configured for a specific interconnect module type. After an Ethernet module
has been physically removed from the enclosure and none of its ports are part of an Ethernet network
and/or Shared Uplink Set, the module can be removed from the Virtual Connect domain. A FC module
can be administratively removed when none of its fabrics are in use by a profile.
