Hi everyone,
I have two computer (A and B) directly connected by an InfiniBand wired.
I'm interested in sending a magicPacket from computer A thoughout the Infiniband wire to wakeup computer B.
My problem is that I'm struggling to enable wake-on-lan on computer B.
Here are steps that I'm following now
1. Turn both InfiniBand ports in Ethernet mode
comA > connectx_port_config (followed by the choice of option 2)
comB > connectx_port_config (followed by the choice of option 2)
2. Confirm that ports are enable
comB > ifconfig
| eth1 | Link encap:Ethernet HWaddr 00:02:c9:4d:58:ee |
| adr inet6: fe80::202:c9ff:fe4d:58ee/64 Scope:Lien | |
| UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 | |

| collisions:0 lg file transmission:1000 | |
| Octets reçus:1901314 (1.9 MB) Octets transmis:2818792 (2.8 MB) |
2. Observe characteristics of the Ethernet port on computer B,
comB > ethtool eth1
Settings for eth1:
Supported ports: [ TP ]
Supported link modes: 10000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: No
Advertised link modes: 10000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: No

MDI-X: Unknown
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000014 (20)

3. Confirm that both port are up
comB > ibstat
CA 'mlx4_0'
CA type: MT26428

Base lid: 0
LMC: 0
SM lid: 0

Link layer: Ethernet
4. Enable the wake-on-lan on computer B
comB > ethtool -s eth1 wol g
Cannot set new wake-on-lan settings: Operation not supported
not setting wol
What am I missing here ?
Any help is welcome !
I'm using Ubuntu 12.04 as operating system and here are characteristifs of both InfiniBand cards
