Hello there,

lp-hea are the native adapters attached to the Balde itself (they are HEA, and each HEA has 4 Logical ports). We use them, say for the first installation or for servers where you don't want redundancy, they are SPOF (single point of failure) adapters.

Virtual adapters (l-lan), are created at VIOS/client level, we create them at VIO level to define the priority of VIOS and add multiple vlans to it. At client level we create those for it to communicate to outer world.

Physical cable are the actual cables from which the traffic goes in and out of the Blade, without the physical port your virtual adapter at VIO are of no use.

Now coming to SEA (shared ethernet adapter), to create a SEA you need a physical adapter, a virtual adapter (actually two, one with trunking priority, vlans (if you want) and other is called control channel adapter, ctrl chan adapter is the heart beat of SEA). Then the VIO create a new adapter called SEA, remember that SEA will not be visible from HMC, you can only see it when you are in VIO.

If you have SEA, it will be redundant and you can avoid SPOF.

NAME
scconf_transp_adap_ce - configure the ce Sun Ethernet transport adapter DESCRIPTION
Note - Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor- mation about the object-oriented command set, see the Intro(1CL) man page. You can configure ce adapters as cluster transport adapters. These adapters can be used with transport types dlpi. The ce adapter is VLAN capable. A ce adapter connects to a transport switch or to another ce adapter on a different node. In either case, the connection is made through a transport cable. When a transport switch is used and the endpoints of the transport cable are configured by using scconf, scinstall, or other tools, you are asked to specify a port name on the transport switch. You can provide any port name, or accept the default, as long as the name is unique for the switch. The default is to set the port name to the node ID hosting the adapter at the other end of the cable. There are no user configurable properties for cluster transport adapters of this type. SEE ALSO
