When a farm goes into standby mode, disk copy operations for all servers belonging to that farm start simultaneously. However, when a failure occurs during the first disk copy operation, for example, not enough disk space, the other disk copy operations continue until all are completed, and then the failure is reported. To resolve this, ping the farm using the command farm -pf farm-ID. Then put the farm in standby using the command farm -s farm-ID. (4849694)
