Recurring Alerts

HI I would like to get alerts on specific intervals until the rearm value is reached.is this possible?

(I have set a threshold value of a partition to 85 and i have reached to 90, of course i got alert as soon i crossed this level.
Until I reach back to less than 85 I should get alerts with an interval of 5 mins. )
i am using OPManger-8 .

Regards,
Rajesh Sharma
