Send a custom AutoSupport message prior to reconfiguring switches
Contributors Download PDF of this page
Before reconfiguring your switches, you should issue an AutoSupport message to notify NetApp technical support that maintenance is underway. Informing technical support that maintenance is underway prevents them from opening a case on the assumption that a disruption has occurred.
This task must be performed on each MetroCluster site.
Log in to the cluster.
Invoke an AutoSupport message indicating the start of the maintenance:
system node autosupport invoke -node * -type all -message MAINT=<maintenance-window-in-hours>
maintenance-window-in-hoursvalue 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
Repeat these steps on the partner site.
