smart array 6404 + msa20 + DL380 G4

I'm having a NAS windows storage 2003 server with 2 MSA20 boxes connected to a 6404 controller on channel A1 and A2.
But when I open the acu I see 2 smartarray controlles (this is normal) and 2 msa20 controllers (??).
The 2 smartarray controllers say they don't have any disks attached. And on the msa20 I can create sata array's.
On 1 of the msa20 controller I have a lot more configuration options (cache settings, rebuild priority,...). On the other I can just create array's an logical volume and he gisves a warning about battery low (is this normal).
Another problem I hav is that I can't do an expand of a logical volume or array and I can't create an array over the 2 boxes.

I have put the msa20, SA 6404 into the latest FW + windows driver and acu are also into the latest version (smart start 7.30)

thanks Koen

MSA20 has own kinda raid ctrl. SA6404 is only gateway to MSAs. Not any SA6404 features to MSA20. And cannot mix 2 MSAs together, like same array or spares. Sorry. I make same mis conclusion.
Also MSA20 has interesting feature when you make raid groups and volumes. Meaning how large raid groups and volumes you can make. This is scsi protocol/code limit.
