标题: RHEL7.6 +VMWARE 不重启识别新添加磁盘
1.虚拟机增加硬盘
我们这里增加500G磁盘

2.确定当前磁盘块设备
# lsblk

NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda             8:0 0  1.7T  0 disk
├─sda1          8:1 0  500M  0 part /boot
├─sda2          8:2 0  132G  0 part
│ ├─centos-root 253:0 0  100G  0 lvm  /
│ └─centos-swap 253:1 0 32G  0 lvm  [SWAP]
└─sda3          8:3 0  1.5T  0 part
  └─vgora-u01 253:2 0  1.5T  0 lvm  /u01
sr0             11:0 1  4.4G  0 rom

3.确定主机总线号
  ls -l /sys/class/scsi_host/

  lrwxrwxrwx 1 root root 0 Jan  1 21:52 host0 -> ../../devices/pci0000:00/0000:00:10.0/host0/scsi_host/host0
  lrwxrwxrwx 1 root root 0 Jan  1 21:52 host2 -> ../../devices/pci0000:00/0000:00:07.1/ata2/host2/scsi_host/host2
  lrwxrwxrwx 1 root root 0 Jan  1 21:52 host1 -> ../../devices/pci0000:00/0000:00:07.1/ata1/host1/scsi_host/host1

4.重新扫描SCSI总线来添加设备
  echo "- - -">/sys/class/scsi_host/host0/scan
  echo "- - -">/sys/class/scsi_host/host1/scan  echo "- - -">/sys/class/scsi_host/host2/scan
5.验证磁盘和分区并确保500GB硬盘已经添加
# lsblk

  NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT

sda             8:0 0  1.7T  0 disk
├─sda1          8:1 0  500M  0 part /boot
├─sda2          8:2 0  132G  0 part
│ ├─centos-root 253:0 0  100G  0 lvm  /
│ └─centos-swap 253:1 0 32G  0 lvm  [SWAP]
└─sda3          8:3 0  1.5T  0 part
  └─vgora-u01 253:2 0  1.5T  0 lvm  /u01
sdb             8:16 0  500G  0 disk

可以看到500g确实已经增加
