Administrator Guide

To apply a detach rule that will determine the behavior of all volumes in a consistency group:
Steps
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
Deleting a consistency group
About this task
To destroy an empty consistency group:
Steps
1. Use the ls -f command to verify that there are no virtual volumes in the consistency group (virtual volumes =
[ ]).
VPlexcli:/> ls clusters/cluster-1/consistency-groups/TestCG
Attributes:
Name Value
-------------------- ----------------------

2. Use the consistency-group destroy command to delete the consistency group.
