Sending a custom AutoSupport message before adding nodes to the MetroCluster configuration
Contributors Download PDF of this page
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 at Site_A.
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-hours specifies the length of the maintenance window and can be a maximum of 72 hours. If you complete the maintenance before the time has elapsed, you can issue the
system node autosupport invoke -node * -type all -message MAINT=end
command to indicate that the maintenance period has ended.
Repeat this step on the partner site.
