System Information during Failover
Synchronous Mode
When a failure occurs on systems with synchronous mode volume groups such that all links between
the systems are broken:
• After 15 seconds, the system marks the sending links as Down.
• After another 15 seconds, the system marks the targets as failed.
Asynchronous Periodic Mode
When a failure occurs on systems with asynchronous periodic mode volume groups such that all
links between the systems are broken:
• After 25 seconds, the system marks the sending links as Down.
• After another 200 seconds, the system marks the targets as failed.
Example Output after Primary System Failure
For example, if the primary system (for example, System1) contains asynchronous periodic mode
volume groups and becomes unavailable, 300 seconds later the showrcopy output on one of the
backup systems (for example, System2) looks like:
# showrcopy
