It is OCUM 7. They have attached configuration. I guess this configuration alerts user every 15 mins if it is not resolved, so this does not shorten as far as I understand. I found how to configure EMS Subscription, I believe it will solve this issue.
EMS Subscription will shorten the time between failure itself and the message being sent to UM. EMS Subscription is for UM to receive messages from ONTAP only.
An alert is *still* required for any notification to be sent to admins.
NOTE: If the alert is configured for repeat notification, that is an alert configuration function and is independent of the source of the event (EMS Subscription or normal polling process) that triggers the alert.
