Unit Details page
Show Unit Details Page
The Unit Details page appears when you click an ID number on the Unit Information page. Because it is a sub-page of Unit Information, the page title in the menu bar continues to display “Unit Information” even when you view details of a unit.
The Unit Details page shows details about a particular unit. The specific information shown depends on what type of unit it is. For example, details about a RAID 5 unit made up of three subunits, each of which contains one drive, will include details about the unit and each subunit, as shown in the figure above. However, if the unit is a Single Disk, only information about one disk will be shown.
Details on this page may include all or some of the following information described below.
To see details about a particular drive, click the VPort # (virtual port number). You’ll see a list of all drives, with the drive you selected highlighted.
Status. The operational status of the unit or subunit: OK, Rebuilding, Migrating, Initializing, Verifying, Degraded, or Inoperable (missing drives). When a unit is Rebuilding, Initializing, or Verifying, the percentage (%) complete is also shown. For status definitions, see Unit Statuses.
Name. The name assigned to the unit by an administrator.
Serial #. The serial number of the unit. This number is assigned by the firmware when the unit is created.
Capacity. The total capacity of the unit (capacities of subunits are not shown).
Type. The type of unit or subunit. RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, or Single Disk.
Stripe. The stripe size of the unit, if applicable.
Parities. The number of parity drives in the RAID unit.
Volumes. Displays the number of volumes in a unit. This is usually 1. If you created a boot volume on this unit, or if you have a unit on which you have enabled the auto-carving policy, you will see the number of volumes into which the unit has been divided. For more information, see Using Auto-Carving for Multi LUN Support.
Subunits. If the unit has subunits, details of the subunits are shown.

Note: If an asterisk (*) appears next to the status of a subunit, there is an error on one of the drives in the subunit. 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.

VPort #. If the unit Type is Disk, Single Disk, the VPort (Virtual Port) to which the drive is connected is shown. For multiple-drive units, the VPort numbers are shown in the subunits section. The VPort number is a link to the Drive Information page.
