Creating a Multilevel RAID
Creating a multilevel RAID (RAID 10 or 50) is similar to creating a
normal RAID 1 or RAID 5 array group. To create a RAID10 or
RAID 50 multilevel RAID, follow these steps:
1 Create and build your array groups as described in Creating an
Array on page 2-20. Do not initiate the build process on any
arrays that you intend to use in a multilevel RAID.
2 After you have created your initial array groups, select
RAID > Create again.
3 Select RAID 0 for the RAID type and click Ok.
4 Select two or more arrays of the same type from the list of
eligible devices, then click Done.
Note: You cannot combine arrays that use different RAID
levels.
5 Select File > Set System Config to begin the build process for
the multilevel RAID.
The Tree View displays the multilevel RAID LSU as
(x,x,x,x) FW RAID-0
with the array groups listed where drives would normally be
listed. Selecting an array group component branches to the hard
drives for that array group. The LSU address is the lowest address
of the array logical addresses that comprise the multilevel RAID.
Deleting an Array
To delete an array, follow these steps:
1 In the left pane, highlight the array that you want to remove.
Then, select RAID > Delete.
