Deleting a Unitwww.3ware.com 133• Go to Administrative Tools > Computer Management, and then selectDisk Management in the list on the left.Only dynamic disks can be expanded with Windows DiskManagement. If the unit is shown as a basic disk, right-click on thedisk icon and change it to a dynamic disk.Older Windows systems cannot convert basic disks into dynamicdisks after the file system has been created.• If the unit is shown as a dynamic disk, right-click on it and chooseExtend Volume to launch the Extend Volume wizard.In Linux and FreeBSD, the tools to expand the partition and file systemcan vary, depending on the kernel version and file system that you areusing. Please consult your Linux/FreeBSD documentation and the 3wareKnowledgebase for more information.Deleting a UnitYou delete a unit—either an array of disks, or a Single Disk—when you wantto reconfigure the unit or use the drives for other purposes.After you delete a unit, the drives appear in the list of Available Drives.If you have incomplete drives, or drives that appear with a message such as“Unsupported DCB,” indicating that they were previously part of a unit on a3ware 7000/8000 series controller, they must be deleted before you use them.(If you want to move a unit from a 7/8000 controller to a 9000 seriescontroller, you must convert the drives first. For more information, see“Moving a Unit from One Controller to Another” on page 138.)Warning: When a unit is deleted, all of the data on that unit will be lost. The drivescannot be reassembled into the same unit because the data on it is erased. If youwant to reassemble the drives into the same unit on another controller, use theRemove Unit button in 3DM instead of the Delete Unit button. Or, if you’re at theBIOS level already, you can shut down the computer and physically move the drivesto another 3ware 9000 series RAID controller. When you restart your system, thecontroller will recognize the unit. For more information see “Moving a Unit from OneController to Another” on page 138.
