9.4.1 Before You Begin...
Creation of arrays, even redundant arrays, allows users immediate access to the arrays. If the
system reboots, the creation process continues where it left off.
CAUTION: In some circumstances, more than eight arrays are possible. They might appear to
function properly, but are not supported.
Note: The array size of the new array is limited to 2.199 TB with some operating systems. Refer to
the operating system documentation for details on maximum array sizes.
Note: The ability to create RAID10 or RAIDABLE arrays may not be available on your system.
9.4.2 Example
To create a 1 GB RAID5 array using disk members 1, 2, and 3, type: rcadm -C -r5 -d 1 2
3 -s 1000
To see more examples, type: rcadm -C -?
9.5 Delete Arrays: rcadm --delete
The rcadm --delete or rcadm -D command allows the user to delete one or more arrays.
CAUTION: Deleting an array permanently destroys all data that is on the array. This action
cannot be undone and it is very unlikely the data can be recovered.
9.5.1 Before You Begin...
 If the operating system is using an array it cannot be deleted.
 If an array is accidentally deleted, and the user wants to try and recover the data, create an
array using the same disks, same size, and same cache, and use the --leave-existing-data
option. This option writes new configuration information to the array while trying to use the
exact same disk space as before.
9.5.2 Example
To delete array 1, type: rcadm -D -a 1
To see more examples, type rcadm -D -?
