How to Schedule Maintenance for Services and Resources

As an administrator, you schedule service and CI maintenance to help ensure peak performance. A maintenance schedule defines a time in the future (which can recur at defined intervals) on which to put a service or CI in maintenance. Because CIs can be in multiple services, they can also have multiple schedules.

Before you schedule maintenance, determine the hours when services and resources could be taken offline without affecting the business. If a server is part of a server farm, for example, it could be maintained during business hours without adversely affecting a service because of the redundancy with the other servers.

Note: CIs in maintenance mode are excluded from custom policy calculations that are related to average or percentage.

Use this scenario to guide you through the process:

1. Review maintenance schedule concepts:
   • Maintenance schedule features and behaviors
   • Maintenance mode and impact analysis
   • Maintenance mode and alert escalation
   • Domain manager maintenance propagation
2. Define the maintenance schedule.
3. Assign the maintenance schedule to services and CIs.
4. (Optional) Perform any of the following actions:
   • Disassociate the maintenance schedule.
   • Delete a maintenance schedule.
   • Set the maintenance mode manually.
   • Make the maintenance mode flag visible on the Alerts tab.
