Asynchronous Periodic Mode System Information during Failover
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 (SystemA) becomes unavailable, the showrcopy output on the
synchronous backup system (SystemB) looks like the following:
# showrcopy
