Can I Attach a Disk to a Server in a Different AZ?

No.

Disks and the server you attach the disks to must be in the same AZ. The same is true for shared disks. A shared disk can only be attached to the servers in the same AZ.

If your disk and server are in different AZs, there are two scenarios:
  • The disk is empty, or data on the disk is no longer needed.

    Delete or unsubscribe from the disk. Then, purchase a new disk in the AZ where the server belongs. For details, see Deleting an EVS Disk.

  • Data on the disk is required.

    Create a backup for the disk using the CBR service. Then, use this backup to create a new disk in the AZ where the server is. For details, see Creating a Cloud Disk Backup and Creating a Disk from a Cloud Disk Backup.
