Copying Arrays: bcadm --create-copy
Document
BC4000-UM100-R
--max-size, -ms
Prints the maximum possible size for an array without actually copying an array.
--name, -n
Identifies an array with a user-supplied name. The name can be up to 30 characters, but only 17 of those
characters display in the BIOS.
--priority, -p
Sets the background initialization task priority from 1 to 10, with 10 being the highest priority.
--scan-array, -sa
Enables a continuous read operation of the specified arrays in the background, accessing every block of the
array from beginning to end. The array scan takes place only when the array is idle (that is, when there is no
input to or output from the array).
--array, -a
Array is a required qualifier used to specify arrays, where <list> identifies the array number.
--disk, -d
A required qualifier used with the
--create
option to specify the disk or disks to be included in the array.

Note:
On Linux, anywhere that an asterisk (*) is used in a command as a wildcard argument, you
need to prevent shell expansion by either adding quotes around the asterisk (' or ") or preceding it
with a backslash (\).
Example 1:
Copy array 1 to a newly created RAID5 set of the same size using all
disks.
bcadm -CC --array 1 --raid5 --disk *
Example 2:
Copy array 1 to a newly created 1-TB RAID50 set using 8 disks with
4 disks in each submember.
bcadm -CC --array 1 --raid50 --sub-member 4 --disk 1 2 3 4 5 6 7 8
--size 1000000
Example 3:
Print the maximum size a copy to a newly created RAID5 array can
be if all disks and the distributed spare option are used. This does not
actually create the new array.
bcadm -CC -a 1 --raid5 --d-spare --disk * --max-size
