  • 0 Ratings

Details

This article explains the Physical Disk Health – Physical disk health retrieval issue check in the Virtual SAN Health Service and provides details about why it might report an error.

Solution

Q: What does the Physical Disk Health - Physical disk health retrieval issue check do?
A: This health check checks whether there is an issue in retrieving the physical disk information from hosts in the Virtual SAN 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 Virtual SAN health 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 Virtual SAN health 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 Virtual SAN health service are responsive.

You can check the status of the Virtual SAN health service on the host.

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 Virtual SAN health service with the following command: /etc/init.d/vsanmgmtd restart

For ESXi version 6.0.0 or 6.0 Update 1, Virtual SAN health service is integrated into the host daemon. Check the host daemon status with the following command: /etc/init.d/hostd status
 
If the ESXi host fails to connect from vCenter Server or is not responsive, first resolve the problems with the host, and then check the health status.
