x306 Sata HostRaid can´t find partition

please i need your help one more time.Very fast!!

As i told, we have an x306 server with 2 Sata disk in raid 1.
All managed by intern Sata HostRaid from IBM.

So if i start the x306, ideata and aarichi will start!
So i see the Raid device, but no partitions!

Only when i start the aaichid, i see both disk, with 3 partition each.
How could it be?
What can i do, to get the partitons back for the raid device?
I ´d like to trouch the server out of window.

If you have an idee for me, please tell me.
