You can use the CloneVolume method to create a copy of a volume. This method is asynchronous and might take a variable amount of time to complete.

The cloning process begins immediately when you make the CloneVolume request and is representative of the state of the volume when the API method is issued. You can use the GetAsyncResult method to determine when the cloning process is complete and the new volume is available for connections. You can use ListSyncJobs to see the progress of creating the clone. The initial attributes and quality of service settings for the volume are inherited from the volume being cloned. You can change these settings with ModifyVolume.
Note: Cloned volumes do not inherit volume access group membership from the source volume.


This method has the following input parameters:

Name Description Type Default value Required
access Access allowed for the new volume. If a value is not specified, the access value does not change. Possible values:
  • readOnly: (Optional) Only read operations are allowed.
  • readWrite: (Optional) Reads and writes are allowed.
  • locked: (Optional) No reads or writes are allowed. If not specified, the access value of the volume being cloned is used.
  • replicationTarget: (Optional) Identify a volume as the target volume for a paired set of volumes. If the volume is not paired, the access status is locked.
string None No
attributes List of name-value pairs in JSON object format. JSON object None No
enable512e Specifies whether the new volume should use 512-byte sector emulation. If unspecified, the setting of the volume being cloned is used. boolean Setting of original volume No
enableSnapMirrorReplication Determines whether the volume can be used for replication with SnapMirror endpoints. Possible values:
  • true
  • false
boolean false No
name Name of the new cloned volume; must be 1 to 64 characters in length. string None Yes
newAccountID AccountID for the owner of the new volume. If unspecified, the accountID of the owner of the volume being cloned is used. integer AccountID of the owner of original volume No
newSize New size of the volume, in bytes. Might be greater or less than the size of the volume being cloned. If not specified, the volume size is not changed. Size is rounded up to the nearest 1MB in size. integer None No
snapshotID ID of the snapshot that is used as the source of the clone. If no ID is provided, the current active volume is used. integer None No
volumeID VolumeID for the volume to be cloned. integer None Yes

Return values

This method has the following return values:

Name Description Type
asyncHandle The handle value used to obtain the operation result. integer
cloneID The cloneID for the newly cloned volume. integer
curve The QoS curve values applied to the clone. JSON object
volume An object containing information about the newly cloned volume. volume
volumeID VolumeID for the newly cloned volume. integer
