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 a primary system containing synchronous mode volume groups (for example,
System1) becomes unavailable, 60 seconds later the showrcopy output on the backup system
(for example, System2) looks like:

# showrcopy
