VMware centos linux不断电识别硬盘

echo '- - -' > /sys/class/scsi_host/host0/scan

echo '- - -' > /sys/class/scsi_host/host1/scan

echo '- - -' > /sys/class/scsi_host/host2/scan

有多少都扫一遍即可，如果嫌麻烦想一次就扫完，就需要alias定义别名了

alias sdisk="echo '- - -' > /sys/class/scsi_host/host0/scan;echo '- - -' > /sys/class/scsi_host/host1/scan;echo '- - -' > /sys/class/scsi_host/host2/scan"

不要忘记添加到.bashrc
