Starting and stopping Metro Mirror, Global Mirror, or active-active relationships by using the CLI

You can use the command-line interface (CLI) to start and stop stand-alone Metro Mirror, Global Mirror, or active-active relationships. Relationships that are members of consistency groups must be started and stopped by using the consistency group CLI commands.

1. To start a Metro Mirror,Global Mirror, or an active-active relationship, run the startrcrelationship command.
   For example, enter the following command:

   startrcrelationship rc_rel_id
   

   Where rc_rel_id is the ID of the relationship that you want to start in a stand-alone relationship.

   Note: Active-active relationships can be started only if they have a state of idling.
2. To stop a Metro Mirror or Global Mirror relationship, run the stoprcrelationship command. This command applies to a stand-alone relationship.

   For example, enter the following command:

   stoprcrelationship rc_rel_id
   

   Where rc_rel_id is the ID of the stand-alone relationship that you want to stop mirroring I/O.

3. To stop an active-active relationship, the following conditions must be met:
   • The -access parameter is specified.
   • The state of the relationship is consistent_copying.
   • The status of the relationship is primary_offline.

   For example, enter the following command:

   stoprcrelationship rc_rel_id -access 
   

   Where rc_rel_id is the ID of the active-active relationship that you want to stop. The -access parameter gives hosts read or write access to a volume in an active-active relationship that contains an older but a consistent image that can be used in a disaster recovery scenario.
