This concludes the example of how to remove the Global Mirror environment that was set up
in 26.3, “Set up the Global Mirror environment using TSO” on page 345.
26.6 Planned outage management using ICKDSF
This section briefly presents an example of a Global Mirror planned outage that is managed
using ICKDSF. The procedure presented here can be used to control a planned Global Mirror
outage that is done to create a data consistent set of D volumes at the remote site.
