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.
Name. 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 6, RAID 10, RAID 50, Single Disk, or Spare. For details
about each of the RAID levels, see “Available RAID Configurations” on
page 6.
Capacity. The logical capacity (size) of the unit. (1KB defined as 1024 bytes)
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. For an explanation of the statuses, see “Unit Statuses”
on page 150.
Identify. Check this box to cause the LED for the drives associated with this
unit to blink in the enclosure. If the box is grayed, identify is not supported.
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. To see if this error condition still exists,
rescan the controller; rescanning will clear the drive error status if the condition no
longer exists.
