When L&TT starts, it performs a device scan to identify all the devices connected to the computer,
either directly or through a SAN. In large SAN environments, this scan can take a long time.
The first time L&TT is run, it must perform a full hardware scan (Hardware Scan option). After
that is done, the results of the scan are automatically saved so that the next time L&TT is started,
the Saved/Manual Scan option can be used. If the Saved/Manual Scan option is selected
before a hardware scan is done, the list of available devices will be empty.
If you select Saved/Manual Scan, the Saved/Manual Scan screen is displayed, as shown in
Figure 22 (page 44) .

To have L&TT rescan the system for new hardware devices, use the rescan command.
Using the saved and manual scan screen
Use the Saved/Manual Scan screen to select the devices that you want L&TT to scan and identify.
This can save time in a large SAN environment if you are using L&TT to test a single device.
Unselected devices are not scanned and displayed in the device list on the L&TT Main screen.
The following command options are available:
•
select —The indicated device or devices are scanned.
•
selectAll —All devices are scanned.
•
clear —The indicated device or devices are not scanned.
•
unselectAll —Clears all devices. No devices are scanned.
•
enterHWAddrManual —Manually enter the hardware address of a device to be scanned.
•
hardwarescan —Performs a full hardware scan. Use this option to update the list of available
devices on the Saved/Manual Scan screen.
•
continue —Starts the indicated scan and proceeds to the main screen.
•
up —Exits the current command level.
•
exit —Exits L&TT.
When the scan is complete, the Main screen is displayed, as shown in Figure 23 (page 45) .
