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, Single Disk, Spare, or 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” on page 92.
Subunits. If the unit has subunits, details of the subunits are shown.
VPort #. If the unit Type is Disk, Single Disk, or Spare, 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.
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.
