Starting with vSphere 7.0 Update 1, vSphere Lifecycle Manager performs regular hardware compatibility checks for the vSAN clusters that you manage with a single image. In addition, certain vSphere Lifecycle Manager operations also trigger an automatic hardware compatibility check. Automated hardware compatibility checks are available for vSAN clusters that use a single image.

For information about hardware compatibility checks and instructions how to manually perform a hardware compatibility check for a cluster or for a single host, see Hardware Compatibility Checks.

vSphere Lifecycle Manager Operations That Trigger a Hardware Compatibility Check

vSphere Lifecycle Manager performs an automatic hardware compatibility check for any vSAN cluster that you manage with a single image in the following cases.
  • You edit the image for the cluster and save the image.

    When you edit and save an image, vSphere Lifecycle Manager starts the Check hardware compatibility of cluster's host with image task even for clusters without vSAN. In such case, vSphere Lifecycle Manager only returns a warning that image hardware compatibility is not verified in non- vSAN clusters.

    If the automatically triggered hardware compatibility task fails, you can still save the new image for the cluster.

  • You initiate a remediation pre-check or remediation.

    The hardware compatibility check is a part of the remediation pre-check and remediation task for vSAN clusters. If a cluster is not vSAN-enabled, vSphere Lifecycle Manager does not perform a hardware compatibility check when you initiate a remediation pre-check or remediation.

    You can configure how vSphere Lifecycle Manager behaves in case of hardware compatibility issues.

  • You add or remove a host to and from the cluster.

    When you add or remove a host to and from the cluster, vSphere Lifecycle Manager invalidates the hardware compatibility check results for the cluster and issues a warning. You must rerun a hardware compatibility check to obtain valid information about potential hardware compatibility issues. Alternatively, you can remediate the cluster or run a remediation pre-check, which both automatically trigger a hardware compatibility check.

Regular Hardware Compatibility Checks

The vSAN Hardware Compatibility List (vSAN HCL) database changes regularly. For example, when VMware certifies new OEM devices, drivers, or firmware, those become part of the vSAN HCL database. Similarly, devices, drivers, or firmware that are not supported anymore are removed from the vSAN HCL database.

Changes in the vSAN HCL database might make your hardware compatibility results invalid and outdated. To provide you with valid hardware compatibility information, vSphere Lifecycle Manager runs a periodic hardware compatibility check against the latest vSAN HCL data.

The periodic hardware compatibility check is a preconfigured scheduled task that you can edit and force to run at any time. By default, the task runs every 24 hours. The scheduled task is configured at a vCenter Server level. If a vCenter Server system contains no vSAN clusters that you manage with a single image, vSphere Lifecycle Manager skips the scheduled hardware compatibility check. This periodic task runs only for vSAN clusters that you manage with a single image.
