Creating Metro Mirror, Global Mirror, or active-active relationships by using the CLI

You can use the command-line interface (CLI) to create Metro Mirror, Global Mirror, or active-active relationships.

1. To create a Metro Mirror relationship, run the mkrcrelationship command.
   For example, enter:

   mkrcrelationship -master master_volume_id 
   -aux aux_volume_id -cluster system_id
   

   Where master_volume_id is the ID of the master volume, aux_volume_id is the ID of the auxiliary volume, and system_id is the ID of the remote clustered system.

2. To create a new Global Mirror relationship, run the mkrcrelationship command with the -global parameter.
   For example, enter:

   mkrcrelationship -master master_volume_id 
   -aux aux_volume_id -cluster system_id -global
   

   Where master_volume_id is the ID of the master volume, aux_volume_id is the ID of the auxiliary volume, and system_id is the ID of the remote system.

3. To create a new relationship with cycling enabled:

   mkrcrelationship -master books_volume -aux books_volume -cluster DR_cluster -global -cyclingmode multi

   Note: Add change volumes to a relationship by issuing chrcrelationship -auxchange or chrcrelationship -masterchange.
4. To create a new active-active relationship, run the mkrcrelationship command with the -activeactive parameter.
   For example, enter the following command:

   mkrcrelationship -master master_volume_id -aux aux_volume_id -cluster system_id -activeactive
   

   Where master_volume_id is the ID of the master volume, aux_volume_id is the ID of the auxiliary volume, and system_id is the ID of the remote system.
