The HP blade switch is not a VPI switch and therefore only work with IB. In one of my previous posts I recommended on on using connectx_port_config tool to configure the card to the right mode. There are 3 modes that the VPI NIC card could have:
1) IB Only - with this mode it can only work with IBM switches
2) Eth only - with this mode is can only work with Eth switches
3) Auto sense - with this mode it can work against either (or VPI switch) and will sense the port against.
For working with Eth. you will need an Eth blade. The connectx_port_config tool should set the mode of the card persistently.
