• Only the following types of data diskss can be resized: SSD cloud disks, Ultra cloud disks, and Basic cloud disks.
• Data disks attached to an instance can be resized only when the instances are in Running or Stopped status.
• If a snapshot is being created on a disk, resizing is not permitted.
• The resizing of a disk attached to an instance takes effect only after the instance is restarted from the console or by using Open APIs.
