Table 1 describes the parameters in the URI.

**Table 1** Parameter description¶
Parameter	Mandatory	Description
server_id	Yes	Specifies the ECS ID in UUID format.

Request¶

None

Response¶

Table 2 describes the response parameters.

**Table 2** Response parameters¶
Parameter	Type	Description
volumeAttachments	Array of objects	Specifies the disks attached to an ECS. For details, see Table 3.
attachableQuantity	Object	Specifies the number of disks that can be attached to an ECS. For details, see Table 4.

**Table 3** **volumeAttachments** parameters¶
Parameter	Type	Description
serverId	String	Specifies the ECS ID in UUID format.
volumeId	String	Specifies the EVS disk ID in UUID format.
id	String	Specifies the mount ID, which is the same as the EVS disk ID. The value is in UUID format.
