# Managing Foreign arrays and Alien arrays

## Foreign arrays

You can export RAID data and transfer the drives and RAID configuration to another enclosure. When you export an array, it is called a foreign array. The array icon is grayed out in the Logical devices view. You cannot perform any action on a foreign array, except view array components.

When you physically remove the component drives from the enclosure, the ServeRAID Manager removes the foreign array icon from the console. When you insert the drives in another enclosure, the ServeRAID Manager displays a foreign array icon in the Logical devices view. You must then import the RAID data to complete the transfer. You may then use the array to store and manage data.

## Alien arrays

If the ServeRAID Manager only partially completes the array configuration process, the resulting array is called an alien array. For example, an alien array might be created if power is interrupted during array creation. You cannot use an alien array to store or manage data. The array icon is grayed out in the Logical devices view. The only action you can perform on an alien array is to delete it.
