Troubleshooting a virtual machine that stops responding or fails when the CD-ROM entry is ATAPI

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• A virtual machine stops responding or fails after being VMotioned between ESX hosts
• Console screen is black
• Console is unresponsive
• Virtual machine is powered off, but was not manually instructed to do so

Resolution

When the CD-ROM is set to ATAPI, migrations between hosts cause the virtual machine to attempt to reconnect to a resource (the CD) that is unavailable on the new host. For this reason the virtual machine may become unresponsive, or fail entirely.

To ensure the virtual machine is configured properly:

1. Locate the virtual machine in the VMware VirtualCenter.
2. Right-click on the virtual machine and select Edit Settings.
3. Choose CD/DVD Drive 1 from the list provided. The options for the drive's configuration are presented on the right of the screen.
4. Reconfigure the virtual machine to connect a Datastore ISO file.
5. Ensure Connected is deselected.
6. Press OK to save the settings.
7. Repeat steps 3-6 for each configured CD/DVD on the virtual machine.
8. Power on the virtual machine.

If the virtual machine was set to "ATAPI", it is possible that this setting was defined by a script that imports the virtual machines. If this is the case, update the script to ensure it does not continue to create virtual machines that experience this issue.
