When HP SSA finishes splitting the array, two logical drives appear in the Arrays menu:

o

When a RAID 1 or RAID 1+0 array splits, two RAID 0 logical drives are created.

o

When an array that contains a RAID 1 (ADM) logical drive splits, a RAID 1 logical drive and a RAID
0 logical drive are created.

o

When an array that contains a RAID 10 (ADM) logical drive splits, a RAID 1+0 logical drive and a
RAID 0 logical drive are created.

11.

Shut down the OS.

12.

Power down the server.

13.

With power off, remove the physical drives that constitute one of the new arrays.
If you do not remove the physical drives for one of the arrays, the OS will be unable to distinguish
between the two arrays when the server is restarted because the arrays are identical.

Power up the server.

15.

Restart the OS.

Recombining a split mirrored array

Choose a device and click Configure in the quick navigation menu.

7.

Select the array to be mirrored to the source array.
This array is usually the array that was split from the original mirrored array. However, it can be any
other array of the correct size.

8.

Click OK.

9.

When HP SSA finishes re-mirroring the array, restart the OS.
The controller uses the rebuild process to synchronize the mirrored drives. The drive online LED flashes
during the rebuild process. Depending on the hard drive size and the server load, this process can take

up to 2 hours. You can boot the OS during this time, but the logical drive is not fault-tolerant until the

rebuild is complete.
