solaris9上装ibm ultrlum-2外置磁带机，
我
devfsadmin
mt -f /dev/rmt/0 status
显示：
/dev/rmt/0: no tape loaded or drive offline
是不是要装驱动？

没有放磁带进去吧，呵呵

显示一个磁带设备的状态
将磁带放入磁带机中，然后：
# mt –f /dev/rmt/0 status
如果你有多于一个磁带设备，设备则是：/dev/rmt/1, /dev/rmt/2…
你可能会看到如下信息：
Quantum DLT7000 tape drive:
sense key(0x0)= nosense residual= 0 retries= 0
file no= 0 block no= 0
sense key(0x0)= nosense表示你的系统可以正常访问磁带。
sense key(0x6)= unit attention表示这个设备可能被重置，或是刚加电的状态
/dev/rmt/0: no tape loaded or drive offline 此信息表示磁带不能访问

no such file or directory 如果你出现了这条信息，你的系统与你的磁带设备无法进行通讯。查看一下，磁带机是否加电，以及连线是否正常，或再次进行：ok. boot –r

就是看不到磁带机的信息，奇怪

在ok下看看，在系统的/dev/rmt/下看看。。。。
