Storage Media File-Set ID | (0088,0130) | User or implementation specific human readable identification of a Storage Media on which the SOP Instances reside.
Storage Media File-Set UID | (0088,0140) | Uniquely identifies a Storage Media on which the SOP Instances reside.
Referenced SOP Sequence | (0008,1199) | A sequence of Items where each Item references a single SOP Instance for which storage commitment is requested / or has been provided.
>Include Table 10-11 “SOP Instance Reference Macro Attributes” |
>Retrieve AE Title | (0008,0054) | Application Entity Title from which the SOP Instance may be retrieved via a network based retrieve service.
>Storage Media File-Set ID | (0088,0130) | The user or implementation specific human readable identifier that identifies a Storage Media on which this SOP Instance resides.
>Storage Media File-Set UID | (0088,0140) | Uniquely identifies a Storage Media on which this SOP Instance resides.
Failed SOP Sequence | (0008,1198) | A sequence of Items where each Item references a single SOP Instance for which storage commitment could not be provided.
>Include Table 10-11 “SOP Instance Reference Macro Attributes” |
>Failure Reason | (0008,1197) | The reason that storage commitment could not be provided for this SOP Instance. See Section C.14.1.1.

### Note

1. Conditions under which Attributes are required (i.e., Retrieve AE Title, etc.) are defined in the Storage Commitment Service Class in PS3.4.

2. Referenced Performed Procedure Step Sequence (0008,1111) was included in this Module in earlier versions, but its use here has been retired. See PS3.4-2001, in which the Attribute was formerly known as Referenced Study Component Sequence.

#### C.14.1.1 Failure Reason

The following values and semantics shall be used for the Failure Reason Attribute:

0110H - Processing failure A general failure in processing the operation was encountered.

0112H - No such object instance One or more of the elements in the Referenced SOP Instance Sequence was not available.

0213H - Resource limitation The SCP does not currently have enough resources to store the requested SOP Instance(s).

0122H - Referenced SOP Class not supported Storage Commitment has been requested for a SOP Instance with a SOP Class that is not supported by the SCP.

0119H - Class / Instance conflict The SOP Class of an element in the Referenced SOP Instance Sequence did not correspond to the SOP class registered for this SOP Instance at the SCP.
