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

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

These steps help create Metro Mirror, Global Mirror, or active-active relationships:

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.
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.
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.
To create a new active-active relationship, run the mkrcrelationship command with the -activeactive parameter.
For example, enter:
```
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.
