VMvare虚拟机添加一块硬盘不重启解决方法

参考 https://linux.cn/article-9231-1.html

1. 添加了磁盘后查看，没有刷新出来

[root@node /]# fdisk -l

Disk /dev/sda: 17.2 GB, 17179869184 bytes
255 heads, 63 sectors/track, 2088 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000aa84a

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2089    16775168   83  Linux
/dev/sda2            2089        2089        1024   82  Linux swap / Solaris

2. 查看主机总线号

root@node /]# ls /sys/class/scsi_host/
host0  host1  host2

3.重新扫描SCSI总线来添加设备

[root@node /]# echo "- - -" > /sys/class/scsi_host/host0/scan
[root@node /]# echo "- - -" > /sys/class/scsi_host/host1/scan
[root@node /]# echo "- - -" > /sys/class/scsi_host/host2/scan

4.fdisk -l 可以看到添加后的磁盘了
