Moving a Unit from One Controller to
Another
After you have configured a unit on a 3ware 9000 series controller, you can
move it to a different 3ware 9000 series controller, and retain the
configuration on the new controller. This is referred to as “array roaming.”
When connecting the unit to the new controller, you do not have to physically
connect the drives to the same ports to which they were connected on the
previous controller. The firmware will still recognize the unit. This feature is
referred to as “disk roaming.”
3DM includes two features that help you do this without powering down the
system, allowing you to hot-swap the unit. The Remove Unit feature lets you
prepare a unit to be disconnected from the controller, and the Rescan feature
checks the controller for drives that are now connected, and updates the 3DM
screens with current information. For details, see “Removing a Unit” on
page 106 and “Rescanning the Controller” on page 113.
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 9500-8, 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 9xxx 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. You will also need to unlock the drives, as
described under “Unlocking Drives Configured on a 9000 Series
Controller” on page 109.
Unlocking Drives Configured on a 9000 Series
Controller
When drives are configured into a unit on a 9000 series controller, they
become locked for use with 9000 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, highlight the unit you want to unlock, and press the
r
key (for
remove). Then shut down the system.
