Figure 4 - 48: Media Scan Screen
There are two options with performing the Media Scan:
1. Media Scan Priority: determines how much of the system resources
will be used for the drive scanning and recalculating process.
2. Iteration Count: 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.
The system can automatically perform a Media Scan according to a preset
task schedule. For more details, please refer to Chapter 11 Data Integrity.
4.10.10 Write Policy
Figure 4 - 49: Write Policy Screen
The Write-back cache setting can be configured differently on each array.
Setting to the default value means the array setting is coordinated with the
controller’s general setting. The controller’s general setting option can be
found in “View and Edit Configuration Parameters” -> “Caching
Parameters” -> “Write-Back Cache.” Note that cached writes are lost if a
power failure occurs.
