VCF 4.1 ON VXRAIL – REDUCE A CLUSTER (REMOVE NODE)

In a previous post I provided an example walk-through of the process for adding a new host to an existing VCF 4.1 on VxRail ‘VI Workload Domain (WLD)’: https://davidring.ie/2020/12/16/vcf-4-1-on-vxrail-expand-a-cluster-add-node/ In this post I will provide an example walk-through of the process for removing a host from a VCF 4.1 on VxRail ‘VI Workload Domain (WLD)’. There are various reasons you may wish to perform this task […]
