"Operating System Not Found" in VMware Console After Delphix Engine Upgrade or Reboot (KBA8347)

 

KBA

KBA# 8347

 

Issue

Following an upgrade or other reboot of Delphix Engine, the VM may fail to respond on network. Further investigation reviewing the Engine VM console may indicate "PXE-M0F: Exiting Intel PXE ROM" and "Operating System Not Found" messages.  Repeated attempts to reboot the VM does not alter the observed behavior.

Resolution

In some VMware ESX configurations, an improper boot order may be configured in the VM BIOS, directing the VM to attempt boot from network before local storage.  This may be indicated by the accompanying VM console events indicating "Network boot...":

In order to confirm and correct this behavior, the VM Options (accessed via Actions > Edit Settings in vSphere) can be altered to enable "Force BIOS setup" on the next reboot. Then, reboot the VM to access the BIOS settings.

In this step, it should also be confirmed that Firmware is set to BIOS.

On the next boot, the VMware administrator can navigate to the Boot tab in the BIOS menu and review and correct the boot order as needed.

In the following example, Network boot from VMware VMXNET3 is above/before Hard Drive, meaning the VM will attempt to boot from the network first.

In the following screenshot example, the Hard Drive options are expanded to illustrate a typical Engine configuration; the number of devices in any configuration may vary. As illustrated, Network boot from VMware VMXNET3 is included after the Hard Drive devices, ensuring that the Engine root disk (0:0) is used first.
