cluster1::> vserver consistency-group snapshot start -vserver vs0 -consistency-group cg1 -parent-consistency-group "-" -snapshot snap1 -start-timeout 60 -comment "2-phase" -snapmirror-label "Label" -consistency-type crash
          (vserver consistency-group snapshot start)
+ The following example starts a 2-phase Snapshot copy named snap2 on a child consistency group named childCg in parent consistency group parentCg on a Vserver named vs0. The Snapshot copy has start-timeout set to "90".
cluster1::> vserver consistency-group snapshot start -vserver vs0 -consistency-group childCg -parent-consistency-group parentCg -snapshot snap2 -start-timeout 90
          (vserver consistency-group snapshot start)
