Maintenance Task Buttons
Below the list of units, a row of task buttons lets you preform maintenance and configura-
tion tasks related to the unit. Before clicking one of these buttons, select the appropriate
unit:
•
Verify Unit
: Puts the selected unit in verifying mode. If verify scheduling is enabled on
the Scheduling page, the unit will not start actively verifying until the scheduled time,
and the status will indicate “Verify-Paused.” (The Unit Details page will indicate
whether a unit is actively verifying.) If verify scheduling is not enabled, clicking
Verify
Unit
begins the verification process.
If the unit you selected to verify is a redundant unit, the redundancy of the unit will be
verified. For example it will check parity for a RAID 5 or check data consistency for a
RAID 1. If the unit you checked is not a redundant unit, verify will do a surface scan
of the media. During verification, I/O continues normally. For RAID 0, single disks,
JBODs, and spares, there is only a slight performance loss. For redundant units, you
can set the background task rate on the Controller Settings page to specify whether
more processing time should be given to verifying or to I/O.
While a unit is verifying, the status changes to Verifying and a
Stop Verify
link
appears in the right-most column of the Unit Maintenance table.
•
Rebuild Unit
: Replaces a degraded drive in a degraded unit with an available drive
and begins rebuilding the RAID. When you select a degraded unit and click
Rebuild
Unit
, a dialog box listing available drives appears, so that you can select the drive you
want to use. If the degraded unit has more than one degraded drives (for example, a
RAID 10 where both mirrored pairs each have a degraded drive), you will repeat this
process a second time.
If rebuild scheduling is enabled on the Scheduling page, the unit will not start actively
rebuilding until the scheduled time, and the status will change to say “Rebuild-
Paused.” (The Unit Details page indicates whether a unit is actively rebuilding.) If
rebuild scheduling is not enabled, the rebuild process will begin right away.
•
Remove Unit
: Removes a selected unit and allows you to unplug the drives and
move the unit to another controller. the data on the unit remain intact.
When you click Remove Unit, you will be asked to confirm that you want to proceed.
When you confirm the removal, the unit number and information will be removed
from 3DM. (Units created in the future can reclaim this unit number.)
Information about the unit remains intact on the drives. This allows the drive or drives
to be reassembled into a unit again on this controller, or if moved to another
controller.
•
Delete Unit
: Deletes the selected unit and allows you to use the drives to create
another unit. The drives appear in the list of Available Drives.
Caution
When a unit is deleted, the data will be permanently deleted: the drives
cannot be reassembled into the same unit. If you want to reassemble
the drives on another controller and access the existing data, use
Remove Unit instead of Delete Unit.
