Other changes to the system (GUI)
The L&TT installation adds the following keys to the Windows registry:
HKEY_LOCAL_MACHINE\Software\Hewlett-Packard\HP Library & Tape Tools
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Reboot criteria
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 and 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, then 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.
Running L&TT from computers without L&TT installed
You can run L&TT without having to install it on the local machine, either by running L&TT from a
CD, USB flash drive or from a shared directory. This feature is only supported on Windows and
Linux.
Running L&TT from a CD or USB flash drive
You can create a version of L&TT that can run directly from a CD or USB flash drive without the
need for installation or alteration of registry settings.
NOTE: It is possible to install L&TT directly onto a USB flash drive using the bundled installer
package, but this will result in the complete removal of any installation of L&TT on the local machine.
To create a version of L&TT that can run from a CD or USB flash drive:
In Windows
1.
Fully install L&TT onto a computer. If desired, also install any necessary firmware files into the
firmware
subdirectory.
2. Remove the logs directory from the L&TT install directory.
3. Write the contents of the L&TT install directory to the root directory of a CD or USB flash drive.
Close the CD.
4. Insert the CD or USB flash drive into any Windows system and run HP_LTT.exe from the
root directory.
In Linux
