Environment

VMware vCenter Server 7.x

 

Cause

This issue occurs when applying the host profile to a host with FCoE adapters. The host executes the command esxcli network nic list to confirm the NICs are present. If this fails to report the NICs present, the host profile fails to apply.

As the FCoE adapters do not appear in the output of esxcli network nic list, applying the host profile fails.

Resolution

Currently, there is no resolution.

To work around this issue, disable the Software FCoE Configuration within the host profile, this allows the host profile to apply correctly.
