Remediate vSAN Policy ‘Out of Date’

Every object in vSAN (OSA) has an assigned storage policy. If no custom policies have been defined, objects are assigned the factory-installed vSAN default policy. Compliance of the selected policy with the current state is checked regularly. If the object is compliant with the assignes policy, the compliance status is set to ‘Compliant’.

However, it can happen that several objects in the cluster show the compliance status ‘Out of Date’. This will be shown in Skyline Health as an informative note. In the example below, several VMs with their vDisks were out of date.

Remediation in vSphere-Client

If there is only one or very few objects, the affected VM can be highlighted in Skyline Health. By doing so, we switch to the context of this VM and we can see details about namespace-object (VM Home) or the vDisks under Configuration > Policies. In the dialog (image below) we can select the object and click on ‘Reapply VM Storage Policy’. Usually this is enough to bring all objects of the VM back to the ‘Compliant’ state.

Remove an unknown Disk from a vSAN Cluster

A failed capacity disk was removed from a vSAN 7 cluster before it could be logically detached from the disk group. The result is a remaining unknown disk device in the disk group that cannot be removed in the vSphere Client.

In such cases, esxcli is sometimes the more powerful tool.

We need to connect by SSH to the affected vSAN host.

Collect Information

Let’s check all registred disk devices on the node.

esxcli vsan storage list

A detailed list of all cache and capacity devices of this host will be displayed.

Output of disk devices (shortened)

Among the 24 active disks was the unknown zombie device. The only remaining feature was the vSAN UUID. The UUID can be used to detach the device from the configuration.

Remains of a physically removed disk in the vSAN configuration.

Extraction

The UUID of the missing unknown device was “52b17786-183b-e85f-f7f3-4befb19f67b0”. Using this information, we can remove it from the configuration.

esxcli vsan storage remove --uuid 52b17786-183b-e85f-f7f3-4befb19f67b0

The process takes a few seconds. Checking again with the esxcli vsan storage list command showed that the device was removed.
