SCR Overview
Additional Uses of SCR

Disaster Recovery

SCR can also help with disaster recovery by showing you a comparison
of the system state before and after recovery. To make disaster recovery
most effective, set scrconfig to collect data weekly or more often, as
described in step 3 above.
1. After restoring your system, ensure that DMI is installed and all
nodes are configured for access by the CMS.
2. Collect data from the restored system:
scrupdate -n node1
#
3. Make sure the data collection was successful:
#
scrstatus
4. Compare that data with the data that existed before the disaster
recovery:
#
scrdiff node1 : time node1 :lastest
5. Make changes to the system to complete the restoration, if
necessary.
This disaster recovery process can be used for more routine situations,
such as preparing for a reboot or an operating system upgrade.
As you see, SCR is a powerful and flexible tool for system
administration and management. You may devise uses for it that we
have not thought of!
