Unit Information Page

The Unit Information page appears when you choose Information > Unit Information from the menu bar, or when you click an ID number on the Controller Summary page.

The Unit Information page shows a list of the units on the controller specified in the drop-down list on the menu bar and provides summary information about each unit.

To see details about a particular unit, click the link in the Unit # column.

Unit #. The unit number assigned to the unit by the firmware. For 9000-series controllers, unit numbers are in sequential order.

Name. For 9000series controllers, if a name has been given to this unit, it shows here. If it is empty, no name has been assigned. You can name your unit in the Unit Names section of the Management > Controller Settings page.

Type. The type of unit, specified during configuration: RAID 0, RAID 1, RAID 5, RAID 10, RAID 50, Single Disk, JBOD, or Spare. For details about each of the RAID levels, see 3ware Serial ATA RAID Controller User Guide.

Capacity. The logical capacity (size) of the unit.

Note: 3DM 2 displays the capacity (in MBytes or GBytes) the same way that Microsoft Windows and Linux operating systems do: as 1KB = 1024 bytes. Previous versions of 3DM 1.x used the 1KB = 1000 bytes definition. Consequently capacities of units listed under 3DM v 1.x may appear to be larger than they do under 3DM 2.

Status. The operational status of the unit: OK, Rebuilding, Initializing, Migrating, Verifying, Degraded, or Inoperable (missing drives). When a unit is Rebuilding, Initializing, Migrating, or Verifying, the percentage (%) complete is also shown.

Note: If an asterisk (*) appears next to the status of a unit, there is an error on one of the drives in the unit. This feature provides a diagnostic capability for potential problem drives. The error may not be a repeated error, and may be caused by an ECC error, SMART failure, or a device error. Rescanning the controller will clear the drive error status if the condition no longer exists.
