Deleting a Unit
www.lsi.com/channel/products 121
Under Windows, use the disk management utility to determine whether
the disk is a basic disk or a dynamic disk.
• Go to Administrative Tools >> Computer Management, and then
select Disk Management in the list on the left.
Only dynamic disks can be expanded with Windows Disk
Management. If the unit is shown as a basic disk, right-click on the
disk icon and change it to a dynamic disk.
Older Windows systems cannot convert basic disks into dynamic
disks after the file system has been created.
• If the unit is shown as a dynamic disk, right-click on it and choose
Extend Volume to launch the Extend Volume wizard.
In other operating systems, 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 system documentation and the LSI
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.
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 9750 controller, you
must convert the drives first. For more information, see “Moving a Unit from
One Controller to Another” on page 127.)
Deleting a Unit through 3DM2
In 3DM2, 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.
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 3DM2 instead of the
Delete Unit button. Or, you can shut
down the computer and physically move the drives (or the enclosure containing the
drives) to another 3ware 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 127.
