Generic SCSI on a Windows Host Operating System
Using the SCSI Generic driver in Windows, VMware Workstation allows your guest operating system to operate generic SCSI devices including scanners, tape drives and other data storage devices in a virtual machine.
Note: In order to access host SCSI devices as Generic SCSI devices from within a virtual machine, you must run VMware Workstation as a user with administrator access.
In theory, generic SCSI is completely device independent, but VMware has discovered it is sensitive to the guest operating system, device class and specific SCSI hardware. We encourage you to try any SCSI hardware you want to use and report problems to VMware technical support.
Note: If you are using generic SCSI devices in a Windows 95, Windows 98 or Windows Me guest operating system and are experiencing problems with the devices, download the latest Mylex® (BusLogic) BT/KT-958 compatible host bus adapter from www.lsilogic.com. This driver overrides what Windows chooses as the best driver, but it corrects known problems.
Preparing a Windows XP or Windows Server 2003 Guest Operating System to Use SCSI Devices
To use SCSI devices in a Windows XP or Windows Server 2003 virtual machine, you need a special SCSI driver available from the download section of the VMware Web site www.vmware.com/download. Follow the instructions on the Web site to install the driver.
Preparing a Windows NT 4.0 Guest Operating System to Use SCSI Devices
Generic SCSI devices use the virtual Mylex (BusLogic) BT/KT-958 compatible host bus adapter provided by the virtual machine. Some guest operating systems guide you through installing the drivers after you install the first SCSI device in the virtual machine. On Windows NT 4.0, however, you may need to install the driver manually, if it is not already installed for a virtual SCSI disk. You should do so before you add a generic SCSI device.
To install the BusLogic driver in a Windows NT 4.0 guest, have your Windows NT installation CD available and follow these steps.
1. Open the SCSI Adapters control panel.
Start > Settings > Control Panel > SCSI Adapters
2. Click the Drivers tab.
3. Click Add.
4. In the list of vendors on the left, select BusLogic.
5. In the list of drivers on the right, select BusLogic MultiMaster PCI SCSI Host Adapters.
6. Click OK.
7. Insert the Windows NT CD when you are prompted. Click OK.
8. Reboot when you are prompted.
Adding a Generic SCSI Device to a Virtual Machine
You can add generic SCSI devices to your virtual machine in the virtual machine settings editor. When you set up a generic SCSI device, the virtual machine must be powered off.
1. If it is not already running, launch VMware Workstation.
Start > Programs > VMware > VMware Workstation
2. Open the virtual machine in which you want to use the generic SCSI device. Make sure the virtual machine is powered off.
3. From the VMware Workstation window, choose VM > Settings. The virtual machine settings editor opens.
4. Click Add to start the Add Hardware Wizard. Click Next.
5. Select Generic SCSI Device, then click Next.
6. Choose the name of the physical device you want to use.
Then choose the virtual device node where you want this device to appear in the virtual machine.
A check box under Device status allows you to specify whether the device should be connected each time the virtual machine is powered on.
7. Click Finish to install the new device.
8. Click OK to save the configuration and close the virtual machine settings editor.
To remove this device, launch the virtual machine settings editor, select the generic SCSI device, then click Remove.
