Environment
VMware Cloud Foundation
Cause
Mismatched host alignment as per FaultDomain in the ClusterExpansion Spec file
Resolution
To resolve the issue follow either of the below methods
Method 1
Change the Preferred FaultDomain to example_primary-az-faultdomain
- Login to vSphere UI
- Browse to Cluster > Configure > vSAN > Fault Domain
- Click on the 3 dots on the example_primary-az-faultdomain and set as Preferred
Method 2
Align the hosts as per the azName in the clusterExpansionSpec
Sample clusterExpansionSpec
Before
{
"clusterExpansionSpec" : {
"deployWithoutLicenseKeys" : true,

After
- host az1-esx05.example.com moved from example_secondary-az-faultdomain to example_primary-az-faultdomain and host az2-esx05.example.com moved from example_primary-az-faultdomain to example_secondary-az-faultdomain
