The Maintenance Window command allows you to temporarily suppress creating incidents. Open a maintenance window to perform system maintenance or any other task that generates alerts. Task examples include rebooting a node, replacing a disk drive in a disk array, installing software, or installing firmware.

You can open a maintenance window for the following:
  • System
  • Collectives
  • Cabinets
  • Chassis
  • Chassis components

You can schedule a maintenance window ahead of time. During an open maintenance window, Server Management continues to collect data, including summary alerts and reports. Alerts that are processed during the maintenance window period are marked with the TVI_Disposition Ignore_Maintenance and the Summary Alert Escalated is marked Maintenance On to suppress incident creation. When you close the maintenance window, make sure you check the Summary Alert Viewer for any pending service actions.

You can extend the duration of the maintenance window while it is open. If you try to extend a maintenance window during server management failure conditions, such as failover or network down, some alerts may be escalated during the update time period due to attempts to recover from the failure.
