显示当前磁盘分区：
[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
确定主机总线号
[root@centos7 ~]# ls /sys/class/scsi_host/ host0 host1 host2
重新扫描SCSI总线来添加设备
[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
试了下可以实现，但据大神说此方法比较危险，慎用！

太粗糙了。
