Deleting a Unit 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 163. 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 "Moving a Unit from One Controller to Another" on page 163.) Deleting a Unit through 3DM In 3DM, the command for deleting a unit is on the Maintenance page. Be sure to follow steps 1 through 3 in the instructions before using the Delete command. To delete 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 157
