3DM 2 Reference Drive Information Port. The port to which the drive is connected. Model. The model of the drive. Capacity. The capacity (size) of the drive. Status. The status of the drive: OK, Not Supported, Not Present, and so forth. If you need help regarding a status displayed here, please contact Technical Support. Remove Drive. The Remove Drive link removes a drive from the controller so that you can safely unplug it. In the Unit Maintenance section, this link is only provided for drives that can be safely removed without creating an inoperable unit. (For example, a RAID 5 missing 2 or more drives or a RAID 0 missing 1 or more drives would become inoperable.) If you remove a drive from a redundant unit, the unit will become degraded. Once a unit has become degraded, additional drives cannot be removed without making it inoperable, so no Remove Drive link will display. 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. Maintenance Task Buttons Below the list of units, a row of task buttons lets you preform maintenance and configuration tasks related to the unit. Before clicking one of these buttons, select the appropriate unit. Verify Unit. Puts the selected unit in verifying mode. If verify scheduling is enabled on the Scheduling page, the unit will not start actively verifying until the scheduled time, and the status will indicate "Verify-Paused." (The Unit Details page will indicate whether a unit is actively verifying.) If verify scheduling is not enabled, clicking Verify Unit begins the verification process. If the unit you selected to verify is a redundant unit, the redundancy of the unit will be verified. For example it will check parity for a RAID 5 or check data consistency for a RAID 1. If the unit you checked is not a redundant unit, verify will do a surface scan of the media. During verification, I/O continues normally. For RAID 0, single disks, JBODs, and spares, there is only a slight performance loss. For redundant units, you can set the background task rate on the Controller Settings page to specify whether more processing time should be given to verifying or to I/O. While a unit is verifying, the status changes to Verifying and a Stop Verify link appears in the right-most column of the Unit Maintenance table. www.3ware.com 101

Model.
The model of the drive.
Capacity.
The capacity (size) of the drive.
Status
. The status of the drive: OK, Not Supported, Not Present, and so forth.
If you need help regarding a status displayed here, please contact Technical
Support.
Remove Drive.
The
Remove Drive
link removes a drive from the controller
so that you can safely unplug it. In the Unit Maintenance section, this link is
only provided for drives that can be safely removed without creating an
inoperable unit. (For example, a RAID 5 missing 2 or more drives or a RAID
0 missing 1 or more drives would become inoperable.) If you remove a drive
from a redundant unit, the unit will become degraded. Once a unit has become
degraded, additional drives cannot be removed without making it inoperable,
so no
Remove Drive
link will display.
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.
Maintenance Task Buttons
Below the list of units, a row of task buttons lets you preform maintenance
and configuration tasks related to the unit. Before clicking one of these
buttons, select the appropriate unit.
Verify Unit.
Puts the selected unit in verifying mode. If verify scheduling is
enabled on the Scheduling page, the unit will not start actively verifying until
the scheduled time, and the status will indicate “Verify-Paused.” (The Unit
Details page will indicate whether a unit is actively verifying.) If verify
scheduling is not enabled, clicking

While a unit is verifying, the status changes to Verifying and a

link appears in the right-most column of the Unit Maintenance table.
