c7000 virtual connect LACP with ProCurve 2910al-24G

[Pier Maria]

Hi,

this is my scenario:

    2 switch 2910al-24G

    1 c7000 with 2 virtual connect

    1 ProLiant BL420c Gen8

    some other servers (outside the enclosure) each one connected to both switch

What I want to do is have 2GB bandwidth on the blade with a LACP trunk.

I connected 2 SFP-RJ45 1GB adapters (from the same virtual connect) to one of my switch.

I created an Ethernet Network that includes the 2 adapters with Smart link enabled, connection mode auto and default LACP timer.

I created and assigned a server profile that include the Network profile just created.

Over my switch I configured the two ports with mode = auto, flow control = enabled, LACP status = passive.

On my switch i correctly see an automatic lacp trunk group created 

   PORT   LACP      TRUNK     PORT      LACP      LACP

   NUMB   ENABLED   GROUP     STATUS    PARTNER   STATUS

   ----   -------   -------   -------   -------   -------

   7      Passive   Dyn1      Up        Yes       Success

   9      Passive   Dyn1      Up        Yes       Success

On virtual connect uplink ports I correctly see the 2 ports active and with same LAG ID (reading on the official documentation it means the LACP trunk is running)

Finally I started transfering data from 2 servers (located outside the enclosure with 1 gb bandwidth each) to the blade just configured

What I expected was see 2 GB but I saw just 1GB

Monitoring the switch's ports I saw all the traffic pass throw just one port leaving the second one in the trunk basically idle

I also tried a static LACP on my switch

   PORT   LACP      TRUNK     PORT      LACP      LACP

   NUMB   ENABLED   GROUP     STATUS    PARTNER   STATUS

   ----   -------   -------   -------   -------   -------

   7      Active    Trk2      Up        Yes       Success

   9      Active    Trk2      Up        Yes       Success

but I got same result just 1 GB

Any idea?
