Dell EMC Metro node 7.1 CLI Guide

Contexts

All contexts.

Syntax

cluster add 


[-c|--cluster] context path

[-t|--to] cluster

[-f|--force]

Arguments

* - argument is positional.

Description

Before a cluster can communicate with the other cluster of a Metro, you must use the cluster add command.

Use the --to argument:

• During system bring-up when no clusters have yet been told about other clusters. In this scenario, any cluster can be used as the system representative.
• Multiple systems have been detected. Connection to multiple systems, is not supported.

  If there only one system actually present, but it has split into islands due to connectivity problems, it is highly advisable to repair the problems before proceeding. Add the given cluster to each island separately.

  If the intention is to merge two existing systems, break up one of the systems and add it to the other system cluster-by-cluster.

Examples

In the following example:

• The cluster add command adds two clusters.
• The cluster summary command verifies that the two clusters have the same island ID:

  VPlexcli:/clusters/> cluster add cluster-1 cluster-2
  VPlexcli:/clusters> cluster summary
  Clusters:
  	Name	Cluster ID	TLA	Connected	Expelled	Operational Status	Health State
	---------	----------	---------	---------	--------	------------------	------------
	cluster-1	1	FNM00103600160	true	false	ok	ok
	cluster-2	2	FNM00103600161	true	false	ok	ok
   Islands:
   Island ID   Clusters
  ----------   -------------------
   1           cluster-1, cluster-2
