• Do not perform a downgrade if servers are powered on or if a server profile migration operation has
been performed since the upgrade. Performing a downgrade under these conditions can result in
duplicate MACs/WWNs in the domain.
• If the VC domain is managed by VCEM, be sure that the domain configuration has not changed,
including the profile configuration, since the upgrade. Changes to the domain might require that you
resynchronize VCEM to the domain or remove the domain from the VCDG. Changes to the profile
configuration can result in duplicate MAC/WWN identifiers.
Stacking Links screen
To access this screen, click the Stacking Links link in the left navigation tree.
Be sure to connect any Ethernet module stacking cables before running the network setup wizard.
IMPORTANT: For a Virtual Connect environment to operate properly, all VC-Enet modules within
the Virtual Connect domain must be interconnected with stacking links. HP strongly recommends
that redundancy be maintained in stacking links to ensure continued connectivity of servers to the
external networks.
This screen enables you to determine whether all stacking cables are properly installed so that all VC-Enet
modules within the domain are interconnected:
• Connection Status indicates whether all of the VC-Enet modules within the domain are interconnected
with stacking cables and accessible. Lack of connection status to all VC-Enet modules results in a critical
alert.
o OK indicates that all modules are connected.
o Failed indicates that one or more modules are not connected properly. Check the cable
connections.
