如何显示磁带机状态

1. 确保磁带已装入磁带机中。
2. 对想要检查状态的每个磁带键入以下命令：

   # mt -f /dev/rmt/drive-number status

以下示例显示了 QIC-150 磁带机 (/dev/rmt/0) 的状态：

$ mt -f /dev/rmt/0 status
Archive QIC-150 tape drive:
sense key(0x0)= No Additional Sense   residual= 0   retries= 0
file no= 0   block no= 0

以下示例显示了 Exabyte 磁带机 (/dev/rmt/1) 的状态：

$ mt -f /dev/rmt/1 status
Exabyte EXB-8200 8mm tape drive:
sense key(0x0)= NO Additional Sense residual= 0  retries= 0
file no= 0   block no= 0

以下示例显示了快速轮询系统并查找其所有磁带机的方法：

$ for drive in 0 1 2 3 4 5 6 7
> do
> mt -f /dev/rmt/$drive status
> done
Archive QIC-150 tape drive:
sense key(0x0)= No Additional Sense   residual= 0   retries= 0
file no= 0   block no= 0
