HP-UX.将本地磁盘数据备份到磁带.HP9000&tape array 5300
备份本地磁盘所有数据到磁带
默认状态下，无须指明文件系统设备号，此时则为 "/dev/rmt/0m" 。但该设备中没有磁带介质或需要应用其他设备时需加参数 "-d" 并指明设备号。

指定磁带机并将其中磁带倒回初始状态
当执行备份操作遇到出现错误，或断网而导致执行过程中断时，常规方法为重新执行备份。此前需要将磁带倒回初始状态，当执行备份操作没有特别指明文件系统设备号时，则均为 "/dev/rmt/0m" 。
# mt -f /dev/rmt/0m rew
输出结果：
此时无输出，当操作执行完毕后，将出现提示符 "#" 。
查询磁带机设备号
当对设备信息了解不充分时，可以通过ioscan查询并获取磁带机文件系统设备号。与此同时，需要对设备物理连接具有印象级了解，因为有些情况下单凭ioscan也是无法彻底分析的。
默认状态中，在HP9000主机磁带设备均为 "/dev/rmt/0m" 。
# ioscan -fnC tape
输出结果：
