Request Syntax

client.modify_instance_maintenance_options(
    InstanceId='string',
    AutoRecovery='disabled'|'default',
    RebootMigration='disabled'|'default',
    DryRun=True|False
)
type InstanceId:

string

param InstanceId:

[REQUIRED]

The ID of the instance.

type AutoRecovery:

string

param AutoRecovery:

Disables the automatic recovery behavior of your instance or sets it to default.

type RebootMigration:

string

param RebootMigration:

Specifies whether to attempt reboot migration during a user-initiated reboot of an instance that has a scheduled system-reboot event:

  • default - Amazon EC2 attempts to migrate the instance to new hardware (reboot migration). If successful, the system-reboot event is cleared. If unsuccessful, an in-place reboot occurs and the event remains scheduled.

  • disabled - Amazon EC2 keeps the instance on the same hardware (in-place reboot). The system-reboot event remains scheduled.

This setting only applies to supported instances that have a scheduled reboot event. For more information, see Enable or disable reboot migration in the Amazon EC2 User Guide.

type DryRun:

boolean

param DryRun:

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

rtype:

dict

returns:
