You can shutdown the machine without risk of data loss, we support node failures. It is better however if you have iSCSI connections on that node to move them to other nodes, and use the shutdown command to power off.

iscsi paths should automatically move to another node that is also providing iscsi targets. If you have multipath enabled and are using it, then your system wont even care that a path change has happened.

If your monitor node has OSDs then use the shutdown command to ensure that those OSDs are fully written to and the journal is complete. The node will correct everything when it comes back up.
