Chapter 8. Configuring Units
164 3ware Serial ATA RAID Controller User Guide
Caution: If you have a configured RAID unit on an older
controller, such as an 8506, and you move the drives to a new
controller, such as 9500-S, you must first convert the units from
7xxx/8xxx format to 9xxx format using a 3ware utility available
from 3ware Technical Support.
You cannot move drives back from the 9500S/9550SX/9590SE
controller to an older controller and maintain the data. If you
want to swap drives back and forth between controller cards, be
sure to have a backup of your data. For 9500S controllers, you will
also need to unlock the drives, as described under “Unlocking
Drives Configured on a 9500S Controller” on page 164.
Unlocking Drives Configured on a 9500S
Controller
When drives are configured into a unit on a 9500S controller, they become
locked for use with 9500S series controllers.
If you want to use these drives on an older 3ware controller, a non-3ware
controller, or connect them directly to a motherboard ATA controller, you
must first unlock them.
You can unlock drives in the following ways:
• In 3BM (3ware BIOS Manager), highlight the unit you want to unlock,
and press the
r key (for remove). Then shut down the system.
• In either 3BM or 3DM, delete the unit, as described under “Deleting a
Unit” on page 157. All data on the drives will be permanently deleted,
and the drives will be unlocked.
• Boot to the operating system. Put a file system on the unit by formatting
and partitioning it. Shut down the operating system cleanly. The drives
will be unlocked.
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.
