Deleting a Unit Only dynamic disks can be expanded with Windows Disk Management. If the unit is shown as a basic disk, you must either convert it to a dynamic disk or use a 3rd party tool to rubrication the unit. „ If the unit is shown as a dynamic disk, right-click on it and choose Extend Volume to launch the Extend Volume wizard. In Linux and FreeBSD, the tools to expand the partition and file system can vary, depending on the kernel version and file system that you are using. Please consult your Linux/FreeBSD documentation and the 3ware Knowledgebase for more information. Deleting a Unit You delete a unit--either an array of disks, or a Single Disk--when you want to reconfigure the unit, or use the drives for other purposes. After you delete a unit, the drives appear in the list of Available Drives. Warning: When a unit is deleted, all of the data on that unit will be lost. The drives cannot be reassembled into the same unit because the data on it is erased. If you want to reassemble the drives on another controller, use the Remove Unit button in 3DM instead of the Delete Unit button. Or, if you're at the BIOS level already, you can shut down the computer and physically move them to another 3ware 9000 series RAID controller. When you restart your system, the controller will recognize the unit. For more information see "Moving a Unit from One Controller to Another" on page 109. 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 a 3ware 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 the 9000 controller, you must convert the drives first. For more information, see the section "Replacing an Existing Controller with a New Controller," in the 3ware 9000 Series Serial ATA RAID Controller Installation Guide.) Deleting a Unit through 3DM 1 Make sure no I/Os are being issued to the unit you want to remove. For example, make sure you are not copying files to the unit, and make sure that there are no applications with open files on that unit. 2 Backup any data you want to keep. www.3ware.com 103
