ZFS Storage for OCI runs on reliable well maintained platform. Occasionally, however, a maintenance event might affect the availability of your cloud resources, so it’s important you are not only informed of scheduled downtime, but also able to prepare for it according to your own business needs.

With the Oracle Cloud Infrastructure Compute service, you can control downtime associated with those rare hardware maintenance events by using Customer Managed VM Maintenance. When a maintenance event is planned for an underlying system that supports one of your instances, you can migrate that instance to other cloud infrastructure by rebooting the instance any time before the scheduled maintenance event.

Approximately two weeks before an actual maintenance event is scheduled, you will receive an email notification from Oracle Cloud Infrastructure. It includes the date and duration of the downtime, a list of instances that are affected by the event, as well as clear instructions on how to move the instance(s) to different infrastructure at any time prior to the maintenance date. It is a good idea to set up the Oracle Cloud Infrastructure account with an email alias that will ensure this notification email will reach the right inboxes.

The same information is also available in the Oracle Cloud Infrastructure Console. Any instance to be affected by the scheduled downtime is marked with the Maintenance Reboot flag.
