The
Copy
option on the
Array
menu is used to create a new array that contains an exact copy of the data on
a source array. The new array does not have to be the same RAID level as the source array. The copy is linked
to the source array upon completion, and as long as the two arrays remain linked, changes to the source are
also made on the copy. The two arrays can be automatically or “manually” unlinked. The copy command is useful
for creating a “snapshot” of a source array at a particular moment in time.
Note:
If your computer screen is not wide enough, only the
Destination View
is displayed.
Notes:
•
You can transform to an equal sized or larger array. You cannot transform to a smaller array size.
•
If a transform is not possible, the
Commit
option is not enabled. A common reason for preventing
a transform is insufficient available space.
Notes:
•
If you select a transformation for which you are not licensed, the
License Issue
message
displays.
•
Unless the transform is instantaneous, the
Array Status
window updates to show the source and
destination arrays along with the progress of the transformation.
Notes:
•
You cannot copy to a smaller-sized array. New arrays must be either the same capacity or larger.
•
The destination array is hidden at the start of the copy. After the arrays are unlinked, the
RAIDConsole
Un-Hide
command can be used to unhide it.
•
If the system reboots during a copy, the copy continues where it left off.
•
If a drive fails while the copy of a redundant array is in progress, no data is lost.
•
If there are multiple arrays on the controller, it may not be possible to copy some of the arrays to
a larger size. If you think that in the future, you will need to expand the size of an array, it is best
to configure the available space as a single array.
•
The array size of the copied array is limited to 2.199 TB on some versions of Windows and Linux.
Please refer to your OS documentation for details on maximum array sizes.
