VMware vSAN (All Versions)
If this health status is not green (OK), HCL information cannot be retrieved from the ESXi host.
The vSAN health service for this host is not working properly, and no HCL information for the host is available.
Two possible causes:
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 Broadcom support to diagnose an unresponsive host.
