Unable to upgrade VMware ESXi when the ESXi
partition table contains a coredump partition
Description: When ESXi is deployed on an SD card by using the dd command, VMware ESXi host creates a coredump
partition as the second partition, during the first boot and does not allow to upgrade the ESXi.
Applies to: ESXi 6.0
Solution: This is a known issue. For more information, refer to the VMware Knowledge Base article 2144074.

Configuring NVMe devices as passthrough device
to the guest operating system, ESXi host stops
responding and results in PSOD
Description: When the NVMe devices are configured as passthrough device to the guest operating system, the host
system stops functioning and can result in data corruption.
Applies to: ESXi 6.0 U2
Solution: You must manually set the Virtual Machine (VM) Memory Mapped Input Output (MMIO) space to 2 GB in
the .vmx file by using the following steps:
NOTE: Do not replace any hardware components while performing these steps.
1. All the VMs configured memory must be reserved. If each VM has 2 GB of memory allocated, you
should reserve all 2 GB. To do this by using the vSphere Client, select the Reserve all guest
memory option from the Memory drop-down menu under the Resources tab in a Virtual Machine’s
Settings window. For more information, see the VMware Knowledge Base article 1010789.
2. For VMs that have more than 2 GB of configured memory, add this parameter to the .vmx file of the
VM: pciHole.start = “2048”.
NOTE: The guest OS should be turned off before editing the .vmx file.
3. By using the vSphere Client, connect NVMe PCIe SSD installer that is configured as passthrough
devices directly to the ESXi host, or select the host in vCenter.
4. Right-click the VM and select Edit Settings.
5. Add a new device by selecting PCI Device from the list, and then click Next.
6. Select the NVMe PCIe SSD as the passthrough device to connect to the VM from the drop-down
list, and then click Next.
7. Click Finish.
8. Download and install the supported drivers for the VM's OS.
9. Reboot the VM.

incorrectly in vSphere Web Client or vCenter Server
Description:
On the Dell PowerEdge C6320 servers, the status and details of power supply unit (PSU) are displayed
incorrectly. The PSU report is displayed as Not Installed on the Hardware Health Status tab, in vCenter
Server. The PSU report is displayed as Normal on the Hardware Health Status tab, in vSphere Web
Client.
Applies to: ESXi 6.0 U2 installed on PowerEdge C6320 server
Solution: Use Dell EMC OpenManage for monitoring or managing the servers with ESXi.
