System Information during Failover
When a failure occurs on systems with synchronous mode volume groups such that all links between
the systems are broken, the following actions occur:
• After 10 seconds, the system marks the sending links as Down.
• After another 10 seconds, the system marks the targets as failed.
Example Output after Primary System Failure
If a primary system containing synchronous mode volume groups (System1) becomes unavailable,
10 seconds later the showrcopy output on the secondary system (System2) looks like the following:
# showrcopy
