Overview

You can attach a separately created disk as a data disk to an instance that resides in the same zone.

Prerequisites

  • The disk resides in the same zone as the instance to which you want to attach the disk.
  • The instance is in the Running (Running) or Stopped (Stopped) state.
  • The disk is in the Available (Available) state.

Context

Before you attach a disk, take note of the following items:

  • Disks that were created along with instances are already attached to the instances.
  • A disk can only be attached to an instance that is located in the same zone and region as the disk.
  • Each disk can be attached only to a single instance at the same time.
  • Each Shared Block Storage device can be attached to up to four instances at the same time.
