Sending a custom AutoSupport message prior to maintenance

Before performing the maintenance, you should issue an AutoSupport message to notify NetApp technical support that maintenance is underway. This prevents them from opening a case on the assumption that a disruption has occurred.

About this task

This task must be performed on each MetroCluster site.


To prevent automatic support case generation, send an Autosupport message to indicate maintenance is underway.
  1. Issue the following command: system node autosupport invoke -node * -type all -message MAINT=maintenance-window-in-hours
    maintenance-window-in-hours specifies the length of the maintenance window, with a maximum of 72 hours. If the maintenance is completed before the time has elapsed, you can invoke an AutoSupport message indicating the end of the maintenance period: system node autosupport invoke -node * -type all -message MAINT=end
  2. Repeat the command on the partner cluster.
