The IBM BladeCenter H chassis has two BNT Layer 2/3 Modules. The HS22 has two gigabit network adapters (Broadcom 5709S). The way the chassis works is one adapter gets mapped to BNT module in bay 1 and the other adapter gets mapped to BNT module in bay 2. This creates a separate switch scenario, which means LACP does not work. This did not seem to be an issue in ESXi 5.0 but appears to be the break point in 5.1. Any ideas?
