I used "PowerCLI Cookbook" to configure esxi 7.0 and just copied and pasted "all" the code - except I changed the subnets. But Synology throws a warning if I try to shutdown the NAS when I try to shut it down. The book does not teach me how to do that. I want to shutdown the NAS because this is a home lab and it is just for cold backups for maybe an hour a week, or so. How can I properly detach the attach iscsi nas?
