Manage power-off for systems and network devices
This section explains power management for systems and network relay devices during copy
operations. This section discusses the following:
•
How to proceed when power is removed from systems or network relay devices due to some
unexpected reason
•
How to intentionally power off systems or network relay devices
“Network relay devices" refers to hardware used for connecting the primary and secondary systems,
such as channel extenders, and switches.
When power stops unexpectedly
This section explains what happens when power is removed from systems or network relay devices
due to an unexpected reason.
CAUTION: When a system is powered on, you must wait five (5) minutes before performing
Continuous Access Journal Z operations; otherwise the pairs could be suspended with a failure.
When power is removed from primary or secondary system
•
If power is removed from the primary system during remote copy operations, the primary
system assumes that a failure has occurred and splits all pairs. When the primary system splits
pairs, the secondary system also assumes that a failure occurs and splits all pairs.
•
If power is removed from the secondary system during remote copy operations, the secondary
system assumes that a failure has occurred and splits all pairs. When the secondary system
splits pairs, the primary system also assumes that a failure occurs and splits all pairs.
