6.5.2 Rescan Disks
The Rescan Command Performs the Following Actions:
 Rescans the SATA channels that search for new, legacy, or removed disks.
 Rereads the configuration information from each disk.
When a disk is offline, it might be brought online by using a rescan. A rescan also stops and then
automatically resumes all tasks.
To rescan disks, select Rescan at the Disk menu.
6.5.3 Change Cache Properties for Disks
The Read Ahead and Write Back Cache properties can be changed if the disks support this option.
The default settings are:
 Read Ahead: enabled.
 Write Back Cache: enabled.
CAUTION: Leaving Write Back Cache enabled can increase the likelihood of data being
corrupted if the system experiences a power interruption or unexpected shutdown.
Note: A disk’s cache setting cannot be changed if a task is active for the array. The cache settings
are enabled when the task is finished.
