Migrating 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 migrating 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 migrate 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 “Migrating Legacy JBOD
Units to a 9000 Controller” on page 24.
Note:
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.
Warning:
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.
