When using PCIE/NVMe SSDs in the capacity layer of Virtual SAN, the SSDs are generating a warning for the “Hardware Compatibility – SCSI Controller on Virtual SAN HCL” health check, even when the devices are on the Virtual SAN HCL.
The “Hardware Compatibility – SCSI Controller on Virtual SAN HCL” health check cannot detect the PCIE/NVMe SSDs because they do not use standard I/O controllers.
To disable the HCL health check alarm use these simple steps:
- In the vCenter Web Client top level, navigate to Manage and select “Alarm Definitions“
- Navigate to the alarm and select Edit
- Deselect the “Enable this alarm” checkbox and click on Finish
Another use case is to disable the HCL health check(s) in non-production lab environments that use Virtual SAN with hardware that is not certified.
