Performs one of the following power actions on the specified instance:

  • START - Powers on the instance.

  • STOP - Powers off the instance.

  • RESET - Powers off the instance and then powers it back on.

  • SOFTSTOP - Gracefully shuts down the instance by sending a shutdown command to the operating system. After waiting 15 minutes for the OS to shut down, the instance is powered off. If the applications that run on the instance take more than 15 minutes to shut down, they could be improperly stopped, resulting in data corruption. To avoid this, manually shut down the instance using the commands available in the OS before you softstop the instance.

  • SOFTRESET - Gracefully reboots the instance by sending a shutdown command to the operating system. After waiting 15 minutes for the OS to shut down, the instance is powered off and then powered back on.

  • SENDDIAGNOSTICINTERRUPT - For advanced users. Warning: Sending a diagnostic interrupt to a live system can cause data corruption or system failure. Sends a diagnostic interrupt that causes the instance’s OS to crash and then reboot. Before you send a diagnostic interrupt, you must configure the instance to generate a crash dump file when it crashes. The crash dump captures information about the state of the OS at the time of the crash. After the OS restarts, you can analyze the crash dump to diagnose the issue. For more information, see Sending a Diagnostic Interrupt.

  • DIAGNOSTICREBOOT - Powers off the instance, rebuilds it on the physical host, and then powers it back on. Before you send a diagnostic reboot, restart the instance’s OS, confirm that the instance and networking settings are configured correctly, and try other troubleshooting steps. Use diagnostic reboot as a final attempt to troubleshoot an unreachable instance. For virtual machine (VM) instances only. For more information, see Performing a Diagnostic Reboot.

  • REBOOTMIGRATE - Powers off the instance, moves it to new hardware, and then powers it back on.

For more information about managing instance lifecycle states, see Stopping and Starting an Instance.


oci compute instance action [OPTIONS]

Required Parameters

--action [text]


--instance-id [text]

The OCID of the instance.

Optional Parameters

--allow-dense-reboot-migration [boolean]

For use with RESET and SOFTRESET actions on instances that use a DenseIO shape, the flag denoting whether reboot migration is performed for the instance. The default value is false.

If the instance has a date in the Maintenance reboot field and you do nothing (or set this flag to false), the instance will be rebuilt at the scheduled maintenance time. The instance will experience 2-6 hours of downtime during the maintenance process. The local NVMe-based SSD will be preserved.

If you want to minimize downtime and can delete the SSD, you can set this flag to true and proactively reboot the instance before the scheduled maintenance time. The instance will be reboot migrated to a healthy host and the SSD will be deleted. A short downtime occurs during the migration.

Caution: When true, the SSD is permanently deleted. We recommend that you create a backup of the SSD before proceeding.

--delete-local-storage [boolean]

For bare metal instances that have local storage, this must be set to true to verify that the local storage will be deleted during the migration. For instances without, this parameter has no effect.

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link:

--if-match [text]

For optimistic concurrency control. In the PUT or DELETE call for a resource, set the if-match parameter to the value of the etag from a previous GET or POST response for that resource. The resource will be updated or deleted only if the etag you provide matches the resource’s current etag value.

--max-wait-seconds [integer]

The maximum time to wait for the resource to reach the lifecycle state defined by --wait-for-state. Defaults to 1200 seconds.

--time-scheduled [datetime]

If present, this parameter will set (or re-set) the scheduled time that the instance will be reboot migrated in the format defined by RFC3339. This will also change the timeRebootMigrationDue field on the instance. If not present, the reboot migration will be triggered immediately.

The following datetime formats are supported:

--wait-for-state [text]

This operation creates, modifies or deletes a resource that has a defined lifecycle state. Specify this option to perform the action and then wait until the resource reaches a given lifecycle state. Multiple states can be specified, returning on the first state. For example, --wait-for-state SUCCEEDED --wait-for-state FAILED would return on whichever lifecycle state is reached first. If timeout is reached, a return code of 2 is returned. For any other error, a return code of 1 is returned.

Accepted values are:

--wait-interval-seconds [integer]

Check every --wait-interval-seconds to see whether the resource has reached the lifecycle state defined by --wait-for-state. Defaults to 30 seconds.
