CGROUP
CGROUP FREEZE immediately removes the paths between the primary and secondary
LSSs. An immediate CGROUP RUN command would end a potential extended long busy
(ELB) timer. Note that ELB is not possible and not useful for Global Copy.
26.4.2 Stop a Global Mirror session
When the local storage disk subsystem is still operational, you may explicitly stop the Global
Mirror session; see Example 26-17.
