NetApp Element software 12.2 and above

Description

When you need to take a storage node offline for maintenance you can minimize the I/O impact to the rest of the storage cluster by enabling maintenance mode for that node.  Maintenance scenarios include any task that requires the node to be powered off or restarted. Maintenance mode does not need to be manually set for upgrades through the HCC (Hyper Cloud Control). This will automatically happen once the update has started.

WARNING

Ensure that you perform maintenance on the node as soon as maintenance mode is enabled. Do not leave the node in maintenance mode any longer than necessary. If the Node is in maintenance mode while offline and unresponsive for more than 12 hours, an outage could occur.
