Moving Units from an 8000 Controller 

to a 9000 Controller

It is possible to move your 8000 storage units to a 9000 series 
controller. You will then have the advantages of the 9000 series 
controller.

The drive units must be in normal mode before moving the units. 
Incomplete, degraded, rebuilding, or initializing units cannot be 
converted. In addition, RAID 0, 10, and 5 units must use a standard 
64 KB stripe size. 

The procedure to move from the 8000 to the 9000 series depends on 
the type of storage unit that you have. For most units, follow the 
steps below. For units using JBOD, see “Moving Units from an 
8000 Controller to a 9000 Controller” on page 23.

In order to preserve the data that is on the units 

attached to the 8000, you will need to run a special 
utility, available from 3ware Technical Support, to 
convert the units to a format that the 9000 controller can 
use. Contact Technical Support to obtain the utility. 
(This utility is not required for legacy JBOD units.)

Do not remove the 8000 board from your system until 
you have converted the units. The units must be attached 
to the 8000 controller when you run the utility.

Drives configured on the 9000 cannot be used 

with older 3ware controllers, non-3ware controllers, or 
directly on the motherboard without first deleting the 
existing configuration to unlock the drive in read only 
mode.
