SCSI Bus Rescan

SCSI Bus rescan

但是一些 SCSI Control Card已經是很久以前的

但 SCSI Device ID 變更, Linux 會還是記著, 不會釋放

只能斷電重新開機或是使用 SCSI bus Delete 指令

1:
 #  echo "- - -" > /sys/class/scsi_host/hostX/scan
  hostX:  0 to n

  #  echo "- - -" > /sys/class/scsi_host/host0/scan
  #  echo "- - -" > /sys/class/scsi_host/host6/scan

 # lsscsi

 # cat /proc/scsi/scsi

2:
 # echo "1" > /sys/class/block/sdX/device/rescan
  sdX:  A to n

  # echo "1" > /sys/class/block/sdb/device/rescan

  # echo "1" > /sys/class/block/sdc/device/rescan

3:

  # echo "1" > /sys/class/scsi_device/6:0:1:0/device/rescan

    6:0:1:0  => Host 6,  ID 1

4:
 # apt-get install scsitools

 # rescan-scsi-bus

 # lsscsi

5:  SCSI bus Delete
echo 1 > /sys/bus/scsi/drivers/sd/6\:0\:6\:0/delete
