命令echo 'scsi remove-single-device a b c d' > /proc/scsi/scsi删除原来的SCSI的设备。
a 表示 SCSI的设备号。
b 表示 CHANNEL号
c 表示 ID号
d 是LUN号 一般都为0
上面四个值同时也是和
ls -l /sys/block/sdc/device
和fdisk -l 命令类似的找出所有磁盘名还有ls -d /sys/block/[sh]d[a-z]
我现在要把原来的HP磁带机去掉。
echo 'scsi remove-single-device 0 0 4 0' > /proc/scsi/scsi 就可以了
cat /proc/scsi/scsi
