CLI Guide

Arguments
Required arguments
[-c|--clusters] cluster * The cluster to expel.
[-f|--force]
Forces the cluster to be expelled.
* - argument is positional.
Description
Cluster expulsion prevents a cluster from participating in a metro node. Expel a cluster when:
● The cluster is experiencing undiagnosed problems.
● To prepare for scheduled outage.
● The target cluster, or the WAN over which the rest of the system communicates, is going to be inoperable for a while.
● An unstable inter-cluster link impacts performance.
An expelled cluster is still physically connected to the metro node, but not logically connected.
The --force argument is required for the command to complete.
Use the cluster unexpel command to allow the cluster to rejoin the island.
Examples
In the following example:
● The cluster expel command expels the cluster.
● The cluster summary and cluster status commands verify the change.
VPlexcli::/> cluster expel cluster-1 --force
Cluster 'cluster-1' has been successfully expelled.
