Use the ls command in the /clusters/cluster-name/consistency-groups context to display the names of
consistency groups only on the specified cluster:
VPlexcli:/> ls /clusters/cluster-1/consistency-groups/
/clusters/cluster-1/consistency-groups:
TestCG test10 test11 test12 test13 test14 test15 test16 test5 test6
test7 test8 test9 vs_RAM_c1wins vs_RAM_c2wins
vs_oban005 vs_sun190
Use the ll command in the /clusters/cluster-name/consistency-groups context to display an overview of the
consistency groups.
Use this command to monitor the overall health of consistency groups and identify poorly-configured rules:
VPlexcli:/clusters/cluster-1/consistency-groups> ll

Use the ls command in the /clusters/cluster-name/consistency-groups/consistency-group context to
display the operational status of the groups.
In the following example, the command displays the operational status of a consistency group on a healthy metro node:
VPlexcli:/> ls /clusters/cluster-1/consistency-groups/cg1
/clusters/cluster-1/consistency-groups/cg1:
VPlexcli:/clusters/cluster-1/consistency-groups/cg1> ls
