We have a requirement for scheduling downtime(unmanaging) for a set of nodes other than Monday to Friday - 8:00 to 17:00. I thought of creating a unmanage schedule and run every day at 5 PM for next 15 hours of downtime. But this solution may not be optimum as we are using an external batch scheduling tool and we have to have 5 jobs to run on each day( and fridays it should be 15+48 hours of downtime). In case of any adhoc request for disabling these nodes for any future days, we can not set it up properly (as this will be overwritten by the scheduled activity which is happening everyday at 5 PM). Could someone be able to provide me a better solution than this?
