Products

Issue/Introduction

This article explains the HCL Health - Host issues retrieving hardware info check in the vSAN Health Service and provides details about why it might report an error.

Environment

VMware vSAN 8.x
VMware vSAN 7.x
VMware vSAN 6.7.x
VMware vSAN 6.5.x
VMware vSAN 6.6.x

Cause

The vSAN health service on one or more ESXi hosts can stop running, or cease responding.

Resolution

Q: What does the HCL Health - Host issues retrieving Hardware Info check do?
A: If this health status is not green (OK), HCL information cannot be retrieved from the ESXi host.

Q: What does it mean when it is in an error state?
A: The vSAN health service for this host is not working properly, and no HCL information for the host is available.


Two possible causes:

1. Host is not responsive or cannot be connected.
2. vSAN 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 vSAN health service are responsive.

You can check the status of the vSAN health service on the host.

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 health service with the following command:

• /etc/init.d/vsanmgmtd restart

It's frequently beneficial to restart health service on vCenter at the same time:

• service-control --stop vmware-vsan-health && service-control --start vmware-vsan-health

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. If needed, please contact VMware support to diagnose an unresponsive host.
