Hi Lorenzo,
yes - you can trust planned switchover. That's what it was designed for.
Please follow the link in order to get to the MetroCluster documentation that has more details on below steps.
https://library.netapp.com/ecm/ecm_download_file/ECMLP2495113
The whole procedure can be performed non-disruptively.
Here what I would suggest:
- perform switchover on the node you want to keep running - the other node will halt and can safely be powered off
- offline the plexes of all aggregates that reside on shelves you plan to power off
- power off bridges
- power off shelves
- relocate all components
- power on shelves - wait 2 min
- power on bridges - wait 2 min
- online the plexes - they will resync automatically
- wait for resync to complete
- perform "metrocluster heal aggregates"
- perform "metrocluster heal root"
- power on node
- perform switchback
Kind regards, Niels
