6.7.1 Logical Drives Maintenance Window
When the Logical Drives maintenance window is opened, the screen shown
in Figure 6-24 should appear.
Figure 6-24: Maintenance - Logical Drives
There are three (3) sub-windows in the Logical Drives maintenance
mode window:
♦ The Logical Drives window provides a list of all configured arrays.
Use a single mouse-click to select the logical drive you wish to
perform maintenance tasks on.
♦ The Front View window allows you to see the locations of logical
drives. Note that a logical drive is selected by a single mouse-click
from the list of configured arrays on the upper screen.
♦ The Functions window provides configuration options for
maintenance tasks and the buttons, which start a maintenance task.
Media Scan - Media Scan examines drives and detects the
presence of bad blocks. If any data blocks have not been
properly committed and are found during the scanning process,
data from those blocks are automatically recalculated,
retrieved and stored onto undamaged sectors. If bad blocks are
encountered on yet another drive during the rebuild process,
the block LBA (Logical Block Address) of those bad blocks
will be shown. If rebuild is carried out under this situation,
rebuild will continue with the unaffected sectors, salvaging the
majority of the stored data.
There are two options with performing the Media Scan:
Operation Priority: determines how much of the system
resources will be used for the drive scanning and recalculating
process.
Operation Mode: determines how many times the scan is
performed. If set to “continuous,” the scan will run in the
background continuously until it is stopped by a user.
