ESX中的Linux熱添加磁盤

      給VM新加了一個磁盤，不想重啟VM又想認出這個磁盤怎么辦呢？

      可以用這個命令：

echo "scsi add-single-device A B C D" >/proc/scsi/scsi

      參數 A、B、C、D 的內容是：

A : SCSI HBA ID
B : SCSI Channel
C : SCSI ID
D : LUN ID

      就下圖的設置命令可以寫成這樣：

echo "scsi add-single-device 1 0 1 0" >/proc/scsi/scsi

      效果如下：

[root@rac02 ~]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0 
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0 
  Type:   Direct-Access                    ANSI SCSI revision: 02
[root@rac02 ~]# 
[root@rac02 ~]# 
[root@rac02 ~]# echo "scsi add-single-device 1 0 1 0" >/proc/scsi/scsi
[root@rac02 ~]# cat /proc/scsi/scsi                                   
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0 
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0 
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 01 Lun: 00
  Vendor: VMware   Model: Virtual disk     Rev: 1.0 
  Type:   Direct-Access                    ANSI SCSI revision: 02

      相反可以使用這個命令移除磁盤：

echo "scsi remove-single-device A B C D" > /proc/scsi/scsi
