To use a device, you must install the appropriate device driver. Tivoli Storage Manager provides its own device driver, ADSMSCSI, for non-IBM devices. The IBM device driver IBMTape is supported for IBM devices. These device drivers are available on the ftp site ftp://ftp.software.ibm.com/storage/devdrvr/. Tivoli Storage Manager also supports third party vendor device drivers if the devices are associated with the GENERICTAPE device class and the hardware vendor also supports that device driver. Using a device class other than GENERICTAPE with a third party vendor device driver is not recommended.
The Tivoli Storage Manager driver lets you exclude devices that are reserved for other applications. Some automated library devices require the Tivoli Storage Manager device driver, and some manual devices can use the Windows device driver with Tivoli Storage Manager.
Selecting the appropriate device driver depends upon the type of device and the media management technique. Devices supported by Tivoli Storage Manager can use the Tivoli Storage Manager device driver, and other devices can use Windows device drivers. The way you set up the two competing device drivers determines which one acquires devices when the server is started.
If you manage a mixture of devices, some can be controlled by the Tivoli Storage Manager device driver and others by the Windows device driver. The Tivoli Storage Manager device driver is recommended, because it allows Tivoli Storage Manager to maintain a volume inventory and to assist with some media management tasks. In some cases, when using Windows Removable Storage Manager (RSM) for example, the Windows device driver must be used and in these cases Tivoli Storage Manager continues to use the devices but with limited Tivoli Storage Manager media management. For devices not currently supported by the Tivoli Storage Manager device driver, the Windows device driver may be suitable.
Table 8 and Table 9 list devices and the device drivers needed
for those devices.

When the operating system is started, the Windows device driver tries to acquire the devices it supports before the Tivoli Storage Manager device driver can acquire devices. Read the following sections to determine how to select the device driver you want.
Windows device drivers provide basic connectivity for devices using Removable Storage Manager (RSM) or native Windows backup tools. Occasionally, you can use devices that are not yet supported by the Tivoli Storage Manager device driver by using the Windows device drivers. The server cannot use all of the devices that Windows device drivers support because some devices do not have all the functions that the server requires. To determine if you can use the Windows device driver with a specific device, see Requirements for Using Windows Device Drivers with Tivoli Storage Manager. You can find the setup procedure for these devices at Configuring Devices Not Supported by the Tivoli Storage Manager Device Driver.
Windows device drivers can be manually started or automatically set to start when the operating system starts. Procedures for controlling these device drivers are described in:
Using Windows device drivers for Tivoli Storage Manager devices limits the server's functionality:
If you add devices and intend to use the Windows device drivers, you should understand that the server does not know device types and recording formats. For example, if you use a Windows device driver for a 4mm drive using the DDS2 recording format, Tivoli Storage Manager knows only that the device is a tape drive and will use the default recording format.
The server cannot prevent errors when it does not know the device type. For example, if one GENERICTAPE device class points to a manual library device containing an 4mm drive and an 8mm drive, the server may make an impossible request: mount a 4mm cartridge into an 8mm drive.
The server cannot report I/O errors with as much detail. Without the Tivoli Storage Manager device driver, the server can obtain only minimal information for display in the server console log.
Devices may be used with Windows device drivers or with the manufacturer's device drivers, but the devices must have the following capabilities:
A file listing devices and their attributes can be created:
c:\program files\tivoli\tsm\console
tsmdlst devlist.txt
notepad devlist.txt
Select from the following device driver setup procedures based upon the device environment.
The Tivoli Storage Manager device driver supports many manual and automated library devices. At many sites, the Tivoli Storage Manager device driver may be all that is required.
The Tivoli Storage Manager device driver is installed with the server, but the device driver is unusable until the default behavior of the Windows device driver is controlled. By default, the Windows device driver tries to acquire all devices when Windows is started. If this happens, the Tivoli Storage Manager device driver is unable to acquire devices. Ensure that the Tivoli Storage Manager device driver acquires the devices that it needs by starting the Tivoli Storage Manager device driver before starting any Windows device driver.
To start the Tivoli Storage Manager device driver before starting any Windows device driver, perform the following procedures from the TSM Console and the Windows Control Panel:
From the TSM Console:
In the Windows Control Panel:
Windows NT |
|
Windows 2000 | If you use Tivoli Storage Manager with Windows 2000, you do not need to explicitly control the Windows device driver's acquisition of devices. When the Tivoli Storage Manager device driver is in boot mode, it automatically acquires all devices not specified in its Device Exclude List. |
Some devices are not supported by the Tivoli Storage Manager device driver, but they can still be used with the server using the Windows device drivers. At sites where a mix of supported and unsupported devices are used, both the Tivoli Storage Manager and the Windows device drivers may be used together.
An example of this scenario is an environment where some data is backed up to an automated library device and some data is backed up to an Iomega Jaz drive. The automated library device requires the Tivoli Storage Manager device driver. However, the Tivoli Storage Manager device driver does not support Iomega Jaz drives so the Windows device driver is used to allow the server to back up to the Iomega Jaz drive.
Perform the following procedures from the TSM Console and the Windows Control Panel:
From the TSM Console:
Use the move button (>) to move a device from the Devices Controlled by the TSM Device Driver pane to the Devices Controlled by Native Device Drivers pane.

Windows 2000 | If you use Tivoli Storage Manager with Windows 2000, you do not need to explicitly control the Windows device driver's acquisition of devices. When the Tivoli Storage Manager device driver is in boot mode, it automatically acquires all devices not specified in its Device Exclude List. |
In some environments, you will want to use the same devices with both the TSM device driver and the Windows device driver. For example, this occurs when devices are used to back up data with Tivoli Storage Manager and then the same devices are used at other times to back up data with a different backup utility. You must reboot the system to switch between applications. The device drivers can be set up to give you the choice of starting either device driver.
To configure a device to use the Tivoli Storage Manager device driver with Tivoli Storage Manager and the Windows device driver with other applications, perform the following two procedures:
Activate the TSM Device Driver:
Activate the Windows Device Driver:

Windows 2000 | If you use Tivoli Storage Manager with Windows 2000, you do not need to explicitly control the Windows device driver's acquisition of devices. When the Tivoli Storage Manager device driver is in boot mode, it automatically acquires all devices not specified in its Device Exclude List. |
By default, the Windows device driver acquires control of supported devices when the operating system is started. In an environment made up entirely of devices unsupported by the Tivoli Storage Manager device driver, you can use this default setting.
To configure all devices to use the Windows device driver, do the following:
