Stacking multiple enclosures enables the management of up to four enclosures from a single control point. VC
Manager operates in the primary enclosure, and it enables up to three additional remote enclosures of the
same type to be added as part of a single VC domain. The locally managed primary enclosure must be
imported into the domain before importing additional (remote) enclosures. If a failure occurs, the standby
module in the primary enclosure takes over.
The VC Manager in the primary enclosure accesses all remote modules and OAs over the management
network. The OAs for each enclosure to be managed as part of a VC domain must be on the same
management subnet along with all of the VC-Enet and VC-FC modules that are in each enclosure. All
enclosure OAs and VC modules within the same VC domain must be on the same lightly loaded subnet. HP
recommends that the OA IP addresses used are configured to be static. The VC-Enet modules use stacking
cables between enclosures to route network traffic from any server port to any uplink port within the VC
domain.
