A vSAN administrator is working on a 4 host homogenous vSAN Cluster that has 2 disk groups per host.
One of the hosts needs to be permanently removed and repurposed for some other use.
These are the out of order steps which need to be completed: 1
Delete the disk group(s) that reside on the host you want to decommission.
2
Wait for resync traffic to complete and the host to enter maintenance mode.
3
Ensure there is sufficient capacity in the vSAN disk groups to decommission a node.
4
Put the host into maintenance mode with full data migration selected.
5
Move the ESXi host out of the cluster.

https://kb.vmware.com/s/article/2148975The correct order of steps to permanently remove a host from a vSAN cluster with 2 disk groups per host is as follows:
Ensure there is sufficient capacity in the vSAN disk groups to decommission a node: Before decommissioning a node, it is important to ensure that there is enough capacity in the remaining disk groups to handle the loss of the node. This step should be performed to avoid any data loss or system downtime due to insufficient capacity.
Delete the disk group(s) that reside on the host you want to decommission: Once you have confirmed that there is enough capacity, the disk group(s) residing on the host you want to decommission should be deleted. This can be done through the vSphere Web Client or through the ESXi command line.
Put the host into maintenance mode with full data migration selected: Once the disk groups have been deleted, the host should be put into maintenance mode. It is important to select the option for full data migration, as this will ensure that all data is moved off the host before it is removed from the cluster. This step is necessary to avoid any data loss or system downtime due to incomplete data migration.
Wait for resync traffic to complete and the host to enter maintenance mode: After putting the host into maintenance mode, it is important to wait for the resync traffic to complete and for the host to enter maintenance mode. This step ensures that all data has been properly migrated off the host before it is removed from the cluster.
Move the ESXi host out of the cluster: Once the host has entered maintenance mode and all data has been properly migrated off the host, the host can be moved out of the cluster. This can be done by removing the host from the cluster using the vSphere Web Client or through the ESXi command line.
Therefore, the correct order of steps is:
D. 4, 3, 2, 1, 5.
