As the first thing that needs verification - are the disks visible to anything, or perhaps broken (so also using the diagnostics DVD is recommended).
If you can access the Web-based ASMI interface (either directly, or HMC as proxy) - also try a factory-reset of everything, and assuming physical access try installs without using the HMC.
At this point, a "simple" HW failure may be the cause, e.g., loose cable during transport.
