Creating a blackout schedule

You can create a blackout schedule either from BMC Helix ITSM: Asset Management or from BMC Helix ITSM: Change Management.

You use the blackout schedule to indicate:

  • Times when the current CI is unavailable for changes in BMC Change Management. During this time, a CI must not be brought down. For example, the server used by payroll might have a blackout schedule to indicate that the CI must not be affected by any changes during paycheck processing.
  • Scheduled outages during which the CI is available for maintenance and other changes. When a CI is available for changes, business services might be affected.

You use the Registration for Shared Time Segment form to create a blackout schedule. You can schedule a blackout to occur once or you can define a recurring schedule. Blackout schedules are stored in the Business Time Segment form. This form is also used by  BMC Helix ITSM: Change Management to help avoid scheduling any changes when a CI must be available.

You can use a one-time blackout schedule to indicate a nonrecurring interval when a CI must be available or is unavailable.

For example, at Calbro Services, a server is hosting a website for a special anniversary event. Allen Allbrook, the configuration administrator, creates a one-time blackout schedule for the week of the anniversary event to prevent the server from being taken down during that week, making sure that the website is available throughout the event. 
You can use a recurring blackout schedule to indicate regular CI availability or unavailability requirements. For example, Finance department at Calbro Services processes payroll checks every Thursday. Allen Allbrook, the configuration administrator, wants to ensure that neither the payroll server nor the payroll printer is taken down for maintenance on Thursdays. He sets two recurring blackout schedules to accomplish this.


Important

The blackout schedule of a CI created in BMC Helix ITSM: Asset Management is not automatically checked when a user with the Infrastructure Change Master, Infrastructure Change Submitter, or Infrastructure Change User permission enters the scheduled dates in the CI change request. However, you can search for available dates by using Schedule Assist in BMC Helix ITSM: Asset Management.
