Status . The status of the drive: OK, Not Supported, Not Present, and so forth.
If you need help regarding a status displayed here, please contact Technical
Support.
Remove Drive.
The Remove Drive link removes a drive from the controller
so that you can safely unplug it. In the Unit Maintenance section, this link is
only provided for drives that can be safely removed without creating an
inoperable unit. (For example, a RAID 5 missing 2 or more drives or a RAID
0 missing 1 or more drives would become inoperable.) If you remove a drive
from a redundant unit, the unit will become degraded. Once a unit has become
degraded, additional drives cannot be removed without making it inoperable,
so no
Remove Drive link will display.
Warning :
Physically removing drives which are not in hotswap
carriers can result in a system hang or may even damage the system
and the drive.
Maintenance Task Buttons
Below the list of units, a row of task buttons lets you preform maintenance
and configuration 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.
Note: If the unit has not previously been initialized and you click
Verify Unit , the initialization process starts. Initialization cannot
be halted, so no Stop Verify link appears. (Initialization can be
paused, however, through Scheduling. Initialization follows the
Rebuild schedule, so turning on scheduling for Rebuild will pause
initialization, as well.) For more information about initialization,
see “About Initialization” on page 119.
