Verifying SCSI Devices in Windows NT
0
When mapping Fibre Channel and SCSI devices, verify the Fibre
Channel and SCSI devices are recognized by the Interface Controller.
Windows NT may need to be rebooted with all SCSI devices and the
Interface Controller powered up before recognizing the devices.
To verify the Fibre Channel and SCSI devices:
1
Navigate to the Windows NT Control Panel, and select SCSI
Adapters.
2
Double-click the Fibre Channel HBA.
The SCSI devices should be listed.
If no devices are listed, verify the Interface Controller configuration,
Fibre Channel HBA configuration, and cabling.
If devices are listed, verify the Fibre Channel HBA mapping mode or
the AL_PA addresses.
Verifying Windows 2000 Driver
0
The Windows 2000 driver is the device driver installation file (called
an INF file) needed by the MS Windows 2000 Operating System. The
Interface Controller needs no driver in reality, as the HBA in the Host
PC manages it. But this file lets the Windows 2000 Device Manager
register a Interface Controller's Controller LUN as a “System” device,
so that the Device Manager thereafter will not consider the controller
LUN to be an unknown or “newly discovered” device with every
reboot. Using this file, a User only has to “identify the Interface
Controller to the Device Manager” once.
To install (register) the Interface Controller with a host Windows 2000
PC that has the FC HBA that will connect to the Interface Controller,
use the included INF file (located on the user documentation CD). A
controller LUN must also set up on the Interface Controller so that
Windows 2000 can “discover” it.
When the Interface Controller FC link is “Up”, the user can either
reboot the PC, or run the “Scan for new Hardware” function of the
Windows 2000 Device Manager. Either action should cause the HBA
to issue a SCSI Inquiry command, to which the Interface Controller
replies with its ASCII Inquiry string. Initially, the Windows 2000
Hardware Wizard will use this string to refer to the Interface
Controller.
After this discovery interaction occurs, the Hardware Wizard will
prompt the user to install a device driver. The user should then select
the Wizard's “Search for a suitable driver” option, and specify the
folder containing the Interface Controller INF file, in this case located
on the user documentation CD.
