从 HP 网站下载 Library and Tape Tools ，包含了磁带库和机械手的驱动程序。
To install the L&TT package:
1.Login as root.
2.Navigate to the temporary directory:
cd /tmp
3.Download or copy hp_ltt.tar (where is the version number) to this directory.
If you are copying the file from a different directory, enter the following command, substituting the directory in which the file currently resides for :
cp //hp_ltt.tar /tmp
4.Un-tar the L&TT tar file:
tar -xvf hp_ltt.tar
5.Run the installation script in the /tmp directory:
./install_hpltt
6.After the software is successfully installed, enter the following commands to remove the temporary files from the installation process:
cd /tmp
rm -rf install_hpltt
rm -rf HPLTT (where is the version number)
安装好驱动程序以后，重新启动操作系统。
reboot -- -r
运行 /opt/ltt/hp_ltt 工具，扫描可以连接到的磁带机设备。在识别出磁带机以后，在cfgadm中可以查看磁带机设备。
cfgadm -al

**测试磁带读写**
在磁带库管理界面中，将磁带入库，测试磁带的读写。磁盘名字中，第一个字符是编号，第二个是磁带密度，可以分为l（低），m（中），h（高），c（压缩的）及u（高压缩的），最后一列中n代表no-rewind，表示操作完以后，不能倒带。
