HP Library and Tape Tools v4.17 Release Notes

Reboot requirements
• A reboot is required only if your system requires ASPI or an upgrade to the currently installed
version. On systems that require ASPI, if the installer detects a previously installed version of ASPI
older than v4.57, it will install a more recent version of ASPI, which will require a reboot.
• On Windows NT and 2000, ASPI is not installed as part of the operating system. If a reboot is
unacceptable, do not select the checkbox for this option in the installation process. If you choose
not to install ASPI, you must use the Miniport driver (Miniport I/O mode) to scan for devices.
• Issues may arise, however, when using the Miniport I/O mode with devices that use non-standard
OS drivers, or are “claimed” by other applications or the OS. When using the Miniport I/O mode
when a device is claimed, it may be necessary to shut down any running backup/storage
application services to make the device accessible to L&TT. Alternatively, using the ASPI I/O mode
may make the device accessible without requiring any further action.
Known issues
• When downloading the L&TT application from the Web to your local system, name the download
folder to something other than HP Library and Tape Tools or the installation will fail if you
attempt to install from that folder. The failure error will indicate that a different instance of the
installer is already running.
• Also, do not rename the L&TT installation file. Renaming the file may create a conflict that prevents
L&TT from installing.
To install the current Windows version of L&TT:
1. Download or copy the self-extracting executable file to a temporary location.
IMPORTANT: Do not rename this file. Renaming the file may create a conflict that prevents L&TT
from installing.
2. Double-click the self-extracting executable file to launch the installer. The InstallShield Wizard
screen is displayed.
3. Click Next. Read the program license agreement and click Yes if you agree to and accept the
terms of the license agreement.
4. Read the readme file for any last-minute changes to the documentation, then click Next. The
Select Features screen is displayed.
5. Select the desired components to install and click Next.
In most cases, the default settings of this screen are adequate. Windows 2000 and Windows XP
users have the option to install Advanced SCSI Programming Interface (ASPI) support. HP does
not recommend installing ASPI support unless you have a good reason to do so.
ASPI support is beneficial when installed storage applications cannot be shut down, and those
applications have locked access to the device through the Miniport driver. If ASPI is installed, it
is generally not necessary to shut down these applications to access devices through L&TT (although
the applications should not be accessing the devices while L&TT is running). ASPI lets you run
L&TT on a locked device without rebooting, but a reboot is required after installing ASPI. The
benefit of using ASPI is not realized the first time L&TT is run, but it is realized on subsequent runs.
One drawback of ASPI is that USB drives are not supported. If you have USB drives, you must
use the Miniport driver.
L&TT supports Microsoft Storport technology. Storport is a new storage driver model created by
Microsoft for Windows Server 2003 and future Windows® operating systems. Storport offers a
higher performance architecture and better Fibre Channel compatibility in Windows systems. If
Storport drivers are installed, L&TT automatically uses Storport when you select Miniport I/O.
