Deleting A Unit Through 3Dm - 3Ware 9650SE-2LPML User Manual

Deleting a Unit through 3DM

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 into the same unit 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 the drives
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 126.
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 a 9000 series
controller, you must convert the drives first. For more information, see
"Moving a Unit from One Controller to Another" on page 126.)
In 3DM, the command for deleting a unit is on the
sure to follow steps 1 through 3 in the instructions before using the Delete
command.
To delete a unit through 3DM
1 Make sure the operating system is not accessing 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.
3 Unmount the unit.
This step is very important.
it is the equivalent of physically yanking a hard drive out from under the
operating system. You could lose data, the system could hang, or the
controller could reset.
