This article explains the vSAN HCL Health – SCSI Controller on vSAN HCL check in the vSAN Health Service and provides details on why it might report an error.Adherence to the VMware Compatibility Guide (VCG)/Hardware Compatibility Guide (HCL) is critically important to the stability of vSAN environments. Experience has shown that failing to observe the VCG often leads to production outages over time. It is, therefore, very important to monitor the health checks in the HCL checker category. For more information, see the VMware Certified Compatibility Guides.
Q: What does the vSAN HCL Health – SCSI Controller on vSAN HCL check do? This check displays information regarding the local storage I/O controller on the ESXi hosts that are participating in the vSAN cluster.The check verifies that this critical piece of the hardware is listed on the VCG. The lookup is performed based on the PCI ID information (Vendor ID, Device ID, SubVendor ID, SubDevice ID). Q: What does it mean when it is in an error state? If this check fails, the first step is to update the VCG database. It is possible that the hardware (or its firmware) got recently added to the VCG. If the device is still not listed in the VCG (and the health check fails), the vSAN environment may be at risk.For more information about this issue, refer to the following article: PCIe or NVMe drives report warning in the vSAN Health Service Q: How does one troubleshoot and fix the error state? For more information how to query the make, model and version of your storage I/O controller, see the Using Esxcli Commands with vSAN (esxcli vsan debug controller list). If you still have difficultly determining storage I/O controller information, contact VMware Support to assess the situation fully. Do not simply rely on the automated health checks.VMware Support will also assist with any mitigation steps. For more information, see How to file a Support Request in Customer Connect (2006985).
