VMware 中很多ATA ChannelX 问题解决方法

出现这种情况的原因，我也不知道，但是我尝试很多种方法，但是可以肯定的是，出现这种情况与 “硬盘”接口没有任何关系，这个尝试了很多次都无济于事。

后来被逼着去官网查问题：

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1012225

即只需要再将对应的虚拟机的配置文件，用写字板打开后，在末尾加上：devices.hotplug = "false"。

就OK了。但是这个也是治标不治本的方法。因为你如果再去“设备管理”中查看，ATA Channel X 还是存在。

以上方法解决了我的需求，就此搁笔。希望有读者，能追根溯源，彻底解决问题。

Disabling the HotAdd/HotPlug capability in ESXi 5.x
and ESXi/ESX 4.x virtual machines (1012225)

Symptoms

NICs and SCSI controllers appear as removable devices.
The Safely Remove Hardware option for the virtual hardware appears
in the Windows System Tray.
When using VMware View, you notice that View desktops that have persistent disks are disconnecting.

Purpose

This article provides information on disabling the HotPlug capability on removable devices.

Resolution

You can disable HotPlug capability using the vSphere Client or by editing the

.vmx

file.

Note: You can disable HotPlug capability for PCI devices such as
e1000 or vmxnet2 NICs.

To disable HotPlug capability using the vSphere Client:

Connect to the ESXi/ESX host or vCenter Server using the vSphere Client.
Power off the virtual machine.
Right-click the virtual machine and click Edit Settings.
Click the Options tab.
Click General > Configuration
Parameters > Add Row.
Insert a new row with the name

devices.hotplug

and
a value of

false

.
Power on the virtual machine.

To disable HotPlug capability using the vSphere Web Client:

From a web browser, connect to the vSphere Web Client.
Log in with Administrator credentials.
Navigate to the virtual machine you want to modify.

Right-click the virtual machine and select Edit Settings.
Click the VM Options tab.
Click Advanced > Edit Configuration > Add
Row.
Insert a new row with the name

devices.hotplug

and
a value of

false

.
Power on the virtual machine.

To disable HotPlug capability by editing the

.vmx

file:

Power off the virtual machine.
Access the ESXi/ESX service console using an SSH client.
Open the virtual machine configuration file (

.vmx

)
in a text editor. The default location is:

/vmfs/volumes/datastore_name/vm_name/vm_name.vmx

Add the line:

devices.hotplug
= "false"

Note: This setting does not interfere with HotPlug CPU/memory.

Save and close the file.
Power on the virtual machine.

Note: If you are using VMware View, perform one of the preceding
procedures for the parent virtual machine first, then perform these steps:

Create a new snapshot of the parent virtual machine:

In the vSphere Client, right-click the parent virtual machine and click Snapshot > Take
Snapshot.
Give the snapshot a name and description.
Click OK.

Recompose the affected pools to this new snapshot:

In the View Manager console, select a pool and open it.
Click View Composer > Recompose,
and select the newly created snapshot.
Click Next.
Configure the Schedule and Warnings options.
Click Next.
Review the confirmation information.
Click Finish and verify that the recompose operation successfully
completes.
Repeat the recompose procedure for all affected pools.
