moving raid 10 to another identical server both on Smart Array 6i controllers

The array configuration in Smart Array RAID controllers is stored on the disks, not the controller. Are you moving to an identical HP ProLiant DL380 G4?

If so, please place the drives in the same spots as they appear on the failed server... E.g. if there's a drive in bay #0 on the old server, place it in bay #0 of the new server. If there's a drive in bay #1 of the old server, place it in bay #1 of the new server... Repeat until done.

On the new system, power on... Pay very close attention to the BIOS messages. You are looking for the 1724 POST code during the array configuration BIOS screen.

1724-Slot X Drive Array - Physical Drive Position Change(s) Detected

That's all you should need to do.
