Sending a custom AutoSupport message prior to reconfiguring switches

Before reconfiguring your switches, you should issue an AutoSupport message to notify Lenovo 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.

1. Log in to the cluster.
2. 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, 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
3. Repeat these steps on the partner site.
