Notification of the number of volumes concurrently queued for on-demand migration is issued to the operator's console (highlighted message ARC1901E). The SETSYS ODMNOTIFICATIONLIMIT(limit) command is used to specify a custom notification limit. The limit parameter is a decimal number 1 to 99999. The default notification limit is 100 volumes.
SETSYS ODMNOTIFICATIONLIMIT(50)
When the number of volumes eligible for on-demand migration falls below the notification limit, message ARC1901E is removed from the operator's console.
