    bootable

    Boolean

    Specifies whether the disk in a replication pair is a system disk.

    volume_size

    Integer

    Specifies the size of the disk in a replication pair. Unit: GB

    volume_type

    String

    Specifies the type of the disk in a replication pair.

    The value can be SSD, SAS, SATA, co-p1, or uh-l1.
