vSAN PCIE/NVMe SSDs Receive Warning for HCL Health Check (2146676)

  • 3 Ratings


If you use PCIE/NVMe SSDs in the capacity layer of a vSAN cluster, the SSDs are issued a warning for the Hardware Compatibility - SCSI Controller on Virtual SAN HCL check in vSAN Health Service. Even though the devices are certified with the correct drivers and firmware versions, an alarm is triggered.


The Hardware Compatibility - SCSI Controller on Virtual SAN HCL health check scans the I/O controllers on storage devices in the vSAN cluster, but it cannot scan PCIE/NVMe SSDs because they do not use standard I/O controllers. These devices use software to provide the function of I/O controllers. Because no I/O controller exists, vSAN Health Service reports that the devices are not compatible.


This issue is resolved in vSAN 6.5 GA, available at VMware Downloads.

To work around the issue, disable the alarm for this health check:
  1. Navigate to the vCenter Server object in the vSphere Web Client, and click Manage  > Alarm Definitions.
  2. Edit this alarm: Virtual SAN Health Alarm SCSI Controller on Virtual SAN HCL.

    Note: These alarms may also be triggered and may be disabled if desired:

    • Virtual SAN Health Alarm Controller Driver
    • Virtual SAN Health Alarm Virtual SAN HCL Health
    • Virtual SAN Health Alarm Controller Release Support

  3. Deselect the Enable the alarm check box.
