drive, will include details about the unit and each subunit, as shown in
Figure 92. 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 Port #. 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” on
page 140.
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, JBOD, or Disk
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 91.
Stripe.
The stripe size of the unit, if applicable.
Subunits.
If the unit has subunits, details of the subunits are shown.
Port #.
If the Type is Disk, Single Disk, JBOD, or Spare, the port to which the
drive is connected is shown. For multiple drive units, the port numbers are
shown in the subunits section. The port 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.
