An existing machine is configured with redundant VIO Servers with SEA failover. A number of
VLANs are already configured and used by the hosted client LPARs. Two additional VLANs are
required to be added to the deployment to support new growth.
An administrator uses a DLPAR operation to add the additional VLANs to the existing Virtual
Ethernet adapters. The attempt failed. They have updated the LPAR profile for both VIO Servers.
Next they shutdown one of the VIO Servers and attempt to reactivate the LPAR. The following
error is displayed:
“HSCL0282 The virtual Ethernet adapter in virtual I/O slot 11 can’t be defined because the
partition with ID 2 already defines a trunk adapter in its virtual I/O slot 11. Please modify the profile
accordingly and reactivate the partition.”
What is the cause of the failure?

A.
It is not possible to add new VLANs to an existing virtual adapter that is part of an SEA failover
environment.

B.
The failed DLPAR operation has not been cleared prior to reactivation of the LPAR profile.

C.
The connectivity required for DLPAR operations has not been configured.

D.
The additional VLANs have not been added to the active VIO Server.
