how to configure my hp 2848 switch to work with c7000 ethernet virual connect module

[csyrmas]

Hi there,

We recently bought a c7000 blade enclosure with 2 ethernet virtual connect modules and 6 blade servers. I have use only one port per vc module (port 1) to connect c7000 case to servers farm switch( its an HP procurve 2848)and i discover that 2 of blade servers looses and restore connection with the network continously. I have configure these two ports to work in trunk group 4 and use LACP but with no luck ( i have not restart c7000 case or switch or move blade servers to another bay). Have anyone an idea what i make wrong? There is any documentation how to configure Procurve 2848 and ethernet virtual connect module?
