Transferring RAID config to One Channel to another

Hi, I am using HP ML 370 Prolaint Server with Smart array 642
Controller which has one internal SCSI Channel and one external SCSI
Channel. What I did was I configured the RAID in external SCSI channel
and I installed the Windows Server 2003. Now lots of huge applications
is running in that server.

Now I want to connect a DLT Drive. But I cannot connnect this to
external SCSI channel(Because I have configured raid on that
channel).

So I need a way to backup the raid configuration in external channel
and restore it to internal channel. so that I can connect my DLT Drive
into external channel.

Once again I memorize my hardware :

HP Proliant ML 370 G4 Server with Smart Array Controller 642.

My Array Configuration utility version 7.30.6.0

Very Big database is running.


Thanks in advance
