Uncouple a RAID Array Copy
Select this option if you want to uncouple a copy from an array. The copy must
be in the Good state before it can be uncoupled. When the copy is uncoupled,
a new hdisk is created. This hdisk contains the copied data.
When this option is selected, a RAID array selection menu is displayed. If you
select a RAID array that has a copy status of good, the copy is uncoupled
from its parent, and a new array is created. The new array uses the next
available hdisk name.
For fast path, type
smitty copy_unarray
and press Enter.
