In one of the host we see Network Adapters & Vlan options disabled in the DCUI interface.
It's HP blade G7 server and updated with firware and patches of ESXi 5.5
Anyone has the solution for it
You're using the Distributed Switch or Standard Switch ?
We are using the dVswitch
Since you're using vDS, all virtual switch tasks, including configuration of VMkernel management interfaces/VLANs must be done on vDS through vCenter and not on ESXi.
