Splitting a mirrored array
This task splits an array that consists of one or more RAID 1+0 logical drives into two identical new arrays
consisting of RAID 0 logical drives. This feature is useful when you want to replicate a configuration or
when you want to build a backup before performing a risky operation.
IMPORTANT:
You cannot split an array if it contains logical drives in RAID 0, RAID 5, or RAID ADG
configurations.
NOTE:
An array can be split or re-mirrored only when the server is offline and operating in the Standard
configuration mode of the ACU GUI.
1.
Take the server offline.
2.
Insert the CD that contains ACU into the CD-ROM drive.
3.
Open ACU, and stay in Standard configuration mode (the default).
4.
Select the controller that contains the array that you want to split.
5.
In the Configuration View panel, select the array.
6.
In the Select a Task panel, click
Split Mirrored Array.
7.
Click
OK.
8.
When ACU has finished splitting the array, remove the physical drives that constitute one of the new
arrays.
IMPORTANT:
If you do not remove one of the arrays, the server will be unable to distinguish between the
two new arrays after it is restarted (next step) because the arrays are identical in all respects.
9.
Restart the server.
Recombining a split, mirrored array
NOTE:
An array can be split or re-mirrored only when the server is offline and operating in the Standard
configuration mode of the ACU GUI.
1.
Take the server offline.
2.
Insert the drives that contain the other half of the split array.
