Check the Hardware Compatibility of a Cluster

For a vSAN cluster that you manage with a single image, you can check the compliance between the image components and the hardware in the cluster. The check is performed against the vSAN Hardware Compatibility List (vSAN HCL) and ensures that if the image is applied to the hosts, the result after remediation is in accordance with the vSAN HCL.

Prerequisites

• Verify that vSAN is enabled for the cluster.
• Verify that the cluster uses a single image.
• Verify that all hosts in the cluster are from the same vendor.
• To validate the compatibility between the PCI device and disk device hardware and target firmware version, verify that the image for the cluster includes a firmware add-on.
• Verify that you have the proper privileges. See vSphere Lifecycle Manager Privileges For Using Images.

Procedure

1. In the vSphere Client, navigate to a vSAN cluster that you manage with a single image.
2. On the Updates tab, select Hosts > Hardware Compatibility.
   In the Hardware Compatibility pane, you see the results from the previous compatibility check.
3. In the Hardware Compatibility pane, click the Run Checks button.

Results

vSphere Lifecycle Manager displays all compatibility information and issues in the Hardware Compatibility pane. You can see detailed compatibility information for each PCI device or disk drive.

What to do next

Review the result from the hardware compatibility check.

Resolve any issues before you remediate the cluster.

Change the Compliance Status of a Disk Device Manually

You can manually change the compliance status of a disk device and mark it as compliant or non-compliant.

In cases when the compliance status of a disk drive is unavailable, you must perform the hardware compatibility check manually and mark the device as compliant or non-compliant.

Prerequisites

• vCenter Server 7.0 Update 3
• Verify that vSAN is enabled for the cluster.
• Verify that the cluster uses a single image.
• Verify that all hosts in the cluster are from the same vendor.
• Verify that you have the proper privileges. See vSphere Lifecycle Manager Privileges For Using Images.

Procedure

1. In the vSphere Client, navigate to a vSAN cluster that you manage with a single image.
2. On the Updates tab, select Hosts > Hardware Compatibility.
   In the Hardware Compatibility pane, you see the results from the previous compatibility check.
3. Click the Disks button.
   You see a list of all non-compliant and compliant disk devices.
4. Click the disk device whose compliance status you want to override.
5. Click the Change Classification button.
   A drop-down menu appears.

   

6. Select the compliance status to apply to the disk device.
   • To mark the issue as compliant, select Mark Issue As Verified.
   • To mark the issue as non-compliant, select Flag as Non-Compliant.
   The Mark Issue As Verified option is not available for compliant devices. The Flag as Non-Compliant option is unavailable if the disk device is non-compliant
7. (Optional) To undo the override selection, select Don't Override from the Change Classification drop-down menu.

Results

You changed the compliance status of a disk device. However, the disk device remains in its original list until you run a new hardware compatibility check.

If you marked the device as verified, a User Reviewed label appears for the disk group.

If you marked the device as non-compliant, a Flagged label appears for the disk group.

What to do next

Run a new hardware compatibility check so that the new compliance status for a disk is saved.
