Marvell RAID Utility Help
The Physical Devices window has three subsections: Physical Disks, Port Multipliers, and Expanders.
The Physical Disks window displays the drives on your computer and indicates the status of each physical drive.
Use the Media Patrol button to detect bad sectors of a configured disk drive. The RAID engine attempts to fix these bad sectors.
Click Legend at the bottom corner for a quick overview
of the physical disk icons.

You can perform the following tasks from this window:

The Port Multipliers window displays general information about all currently connected port multiplier devices, as shown in Figure 3-7. A port multiplier device allows you to expand ports for SATA drives. Only SATA drives can connect to a port multiplier device.
For more detailed information about a port multiplier, click its icon to open the Port Multiplier Details window.
The Expanders window provides information about all currently connected expanders. Expanders offer greater expansion capabilities and can only connect to SAS ports. Both SAS and SATA drives can connect behind an expander.
For more detailed information about an expander, click its icon to open the Expander Details window.
