Prerequisites

• A firmware update may be required. HP LTFS will check and tell you if your tape drive needs up-

dating.

• You must also determine whether you want to use precompiled binaries or build your own version

of the HP LTFS application.

• Linux: The precompiled binaries supplied by HP require additional shared libraries which may

not be present on every system, or which may need to be updated in order for the binaries to

execute. Specifically, this release of HP LTFS requires FUSE libraries v2.8 or later, and icu libraries

v4.2 or later. These may be available from your Linux installation media or from the web; refer

to http://fuse.sourceforge.net/ and http://icu-project.org/ for more details of how to obtain,

build and install those libraries.

• Linux: The FUSE kernel mode subsystem must be present and loaded.

To check, execute the following command:

$ lsmod | grep fuse

If the module is not currently loaded, you can load it as follows:

$ modprobe fuse

If the module is not present on your system, you must first obtain and install it. Refer to http://

fuse.sourceforge.net/ for further information.

• Mac OS X: The MacFUSE module version 2.0.3,2 must be present and loaded.

If the module is not present on your system, you must first obtain and install it. Details of how to

do this are beyond the scope of this document; refer to http://code.google.com/p/macfuse/ for

further information.
