顯示當前磁盤分區：
[root@centos7 ~]# fdisk -l</p>< p> Disk /dev/sda: 32.2 GB, 32212254720 bytes, 62914560 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x0006b96a Device Boot Start End Blocks Id System /dev/sda1 * 2048 1026047 512000 83 Linux /dev/sda2 1026048 62914559 30944256 8e Linux LVM Disk /dev/mapper/centos-swap: 2147 MB, 2147483648 bytes, 4194304 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/centos-root: 29.5 GB, 29536288768 bytes, 57688064 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
確定主機總線號
[root@centos7 ~]# ls /sys/class/scsi_host/ host0 host1 host2
重新掃描SCSI總線來添加設備
[root@centos7 ~]# echo "- - -" > /sys/class/scsi_host/host0/scan [root@centos7 ~]# echo "- - -" > /sys/class/scsi_host/host1/scan [root@centos7 ~]# echo "- - -" > /sys/class/scsi_host/host2/scan
試了下可以實現，但據大神說此方法比較危險，慎用！

太粗糙了。
