In certain circumstances, the task of configuring vSAN on a particular host might fail.
An ESXi host that joins a vSAN cluster fails to have vSAN configured.
If a host does not meet hardware requirements or experiences other problems, vSAN might fail to configure the host. For example, insufficient memory on the host might prevent vSAN from being configured.
- Place the host that causes the failure in Maintenance Mode.
- Move the host out of the vSAN cluster.
- Resolve the problem that prevents the host to have vSAN configured.
- Exit Maintenance Mode.
- Move the host back into the vSAN cluster.
