Resolution
Q: What does the Physical Disk Health - Physical disk health retrieval issue check do?
Q: What does it mean when it is in an error state?
Q: How does one troubleshoot and fix the error state?
A: This health check verifies if there is an issue in retrieving the physical disk information from hosts in the vSAN cluster. If this health status is not green (OK), physical disk information cannot be retrieved from the ESXi host.
Q: What does it mean when it is in an error state?
A: The vSAN management service for this host is not working properly, and no physical disk information for the host is available.
One possible cause of this problem is that the host is not responsive or cannot be connected. Another possible cause is that the vSAN management service on this host has stopped or is not responding.

Q: How does one troubleshoot and fix the error state?
A: Verify that the host and the vSAN management daemon are responsive.
-
For ESXi 6.0 Update 2 or later, use SSH to log into the host and check the status with the following command: /etc/init.d/vsanmgmtd status
-
You also can manually restart the vSAN management daemon with the following command: /etc/init.d/vsanmgmtd restart
-
For ESXi version 6.0.0 or 6.0 Update 1, vSAN health service is integrated into the host daemon. Check the host daemon status with the following command: /etc/init.d/hostd status
-
Review any errors related to physical disk status in /var/log/vsanmgmt.log
Verify that the latest supported controller driver and firmware combinations are in use.
Verify that all the physical disks are showing in a healthy state.
If the ESXi host fails to connect to vCenter Server or is not responsive, first resolve the problems with the host, and then check the health status.
Note: If you have recently updated the hosts to a newer ESXi 6.7 version and encounter this warning in the vSAN health check, make sure that your vCenter Server is at an equal or higher version than the ESXi hosts.
Also, you can check the VMware interoperability matrix to verify the compatibility between vCenter and ESXi versions. To access this website please refer to the following link: https://interopmatrix.vmware.com/
