What is vSAN Configuration Assist
Configuration Assist is the new feature released with vSAN 6.6 and it helps to check the configuration of your vSAN cluster, and resolve any issues. vSAN Configuration Assist enables you to verify the configuration of cluster components, resolve issues, and troubleshoot problems.
The Configuration Assist checks are divided into categories. Each category contains individual configuration checks.
Configuration Assist Categories
There are many vSAN recommendations/checks that are not configured as part of the vSAN cluster configuration wizard .To configure all of them we have to perform individual configuration from vSphere Web Client . Here Configuration Assist simplify the things , we can do all these configuration from single location in the UI.
Navigate to vSAN Cluster -> Configure -> vSAN and Select Configuration Assist
Expand each option to view detail information
Lets check how can we fix one of the configuration issues – vMotion .
Click on the Warning Message o – All hosts have a vMotion vmknic configured
You Can see there 3 nodes on the vSAN cluster and there is not vmotion configured on all three
Next verify vmotion configured on one host and rerun the test and check
Click on the one of the node and check enabled services or edit on the vmk0 and check
As we found there is vMotion not configured , lets enable on the vmk0 and click ok , you can check on the enabled services
Go to the Configuration Assistant and check the status , There is some new error related vmotion and its shows only in two nodes , because we have configured vmotion only one node , lets configure vmotion on other nodes and check again .
Navigate to Configuration Assist and verify the vmotion issue fixed , also there is options Ping Drops and Ping Results
You can see pings Result will show communication of vmotion network is available , and any failure or drops will shows on ping failed pings .
The same way we can fix other issues also with help of Configuration Assist , Reference
