Chapter 6. 3ware Disk Manager (3DM 2) Warning: Physically removing drives which are not in hotswap carriers can result in a system hang or may even damage the system and the drive. Delete Unit. Deletes the selected unit and allows you to use the drives to create another unit. The drives appear in the list of Available Drives. Caution: Before you click Delete Unit, make sure the unit you are removing is unmounted and no I/Os are being issued. If a unit is not unmounted and you delete it, it is the equivalent of physically yanking a hard drive out from under the operating system. Resulting behavior depends on which operating system you are using and what kind of I/O is being done, however you will typically see really bad results, bad errors, and most likely a reset of the controller or a system hang. Devices can be unmounted through the operating system. For details, see the discussion under Remove Unit, above. Warning: When a unit is deleted, the data will be permanently deleted: the drives cannot be reassembled into the same unit. If you want to reassemble the drives on another controller and access the existing data, use Remove Unit instead of Delete Unit. After deletion, the operating system is notified that the unit was deleted. In Linux the device node associated with this unit is removed. In Windows the Device Manager will reflect the changes under the disk drives icon. Available Drives (to Create Units) This section lists the drives on the controller which are not currently configured as part of a unit. The Port number, model, capacity, and status are all displayed, as they are for drives in existing units. Remove Drive. The Remove Drive link removes a drive from the controller so that you can safely unplug it. Any drive in the Available Drives list can be removed. Warning: Physically removing drives which are not in hotswap carriers can result in a system hang or may even damage the system and the drive. Create Unit Use the Create Unit button to create a unit for use on the current controller.

Warning:

Physically removing drives which are not in hotswap

carriers can result in a system hang or may even damage the system

and the drive.

Delete Unit.

Deletes the selected unit and allows you to use the drives to

create another unit. The drives appear in the list of Available Drives.

Caution:

Before you click

Delete Unit

, make sure the unit you are

removing is unmounted and no I/Os are being issued. If a unit is

not unmounted and you delete it, it is the equivalent of physically

yanking a hard drive out from under the operating system.

Resulting behavior depends on which operating system you are

using and what kind of I/O is being done, however you will

typically see really bad results, bad errors, and most likely a reset

of the controller or a system hang.

Devices can be unmounted through the operating system. For

details, see the discussion under

Remove Unit

Warning:

When a unit is deleted, the data will be permanently

deleted: the drives cannot be reassembled into the same unit. If you

want to reassemble the drives on another controller and access the

existing data, use

Remove Unit

instead of

Delete Unit

After deletion, the operating system is notified that the unit was deleted. In

Linux the device node associated with this unit is removed. In Windows the

Device Manager will reflect the changes under the disk drives icon.

Available Drives (to Create Units)

This section lists the drives on the controller which are not currently

configured as part of a unit. The Port number, model, capacity, and status are

all displayed, as they are for drives in existing units.

Remove Drive.

The Remove Drive link removes a drive from the controller

so that you can safely unplug it. Any drive in the Available Drives list can be

removed.
