Example of modify: apply a detach rule

The following table lists the applicable detach-rules for consistency groups with various settings for visibility and storage-at-clusters.

1. Use the ll command to display the current detach rule (if any) applied to the consistency group:

   VPlexcli:/clusters/cluster-1/consistency-groups/TestCG2> ll
   Attributes:
   Name                  Value
   --------------------  ----------------------
   active-clusters       []
   cache-mode            synchronous
   detach-rule           -
   .
   .
   .

2. Use one of the consistency-group set-detach-rule commands to apply a detach-rule to the consistency group:
   • Use the consistency-group set-detach-rule no-automatic-winner command to set the detach-rule as no-automatic-winner.

     In the following example, the command is used in the target consistency group’s context:

     VPlexcli:/clusters/cluster-1/consistency-groups/TestCG> set-detach-rule no-automatic-winner

   • Use the consistency-group set-detach-rule winner command to specify which cluster is the winner, and the number of seconds metro node waits after a link outage before detaching the winning cluster.

     In the following example, the command is used in the root context:

     VPlexcli:/> consistency-group set-detach-rule winner --cluster cluster-1 --delay 5s --consistency-groups TestCG
