Steps to Remove a Host from a vSAN-Enabled Cluster

BCD.

When removing a host from a vSAN-enabled cluster, there are three important steps that should be taken:

1. Remove VMkernel port with vSAN traffic checkbox checked: Before removing a host from a vSAN-enabled cluster, it is important to remove the VMkernel port that is used for vSAN traffic. This can be done by going to the networking section of the vSphere Web Client, selecting the host, and then selecting the VMkernel port with vSAN traffic checkbox checked. This step ensures that the vSAN traffic is no longer directed to the host being removed.

2. Remove the host from vSAN cluster: After the VMkernel port has been removed, the host can be removed from the vSAN cluster. This can be done by selecting the host in the vSphere Web Client and clicking on the "Remove from Cluster" option. This step ensures that the host is no longer part of the vSAN cluster and that its storage resources are no longer used for vSAN data.

3. Remove disks from disk groups, remove disk groups: Once the host has been removed from the vSAN cluster, the next step is to remove any disks that were used for vSAN data. This can be done by going to the vSAN section of the vSphere Web Client, selecting the host, and then selecting the disk group. From there, you can remove the disks from the disk group and then remove the disk group itself. This step ensures that the host's storage resources are fully disassociated from the vSAN cluster and can be used for other purposes.

It is worth noting that before removing the host from the vSAN-enabled cluster, it is important to place it in maintenance mode with Full Migration option selected. This will ensure that any virtual machines running on the host are migrated to other hosts in the cluster before the host is removed. Additionally, creating a vSphere Standard Switch is not necessary for removing a host from a vSAN-enabled cluster.
