For example, A204 means primary volume is disabled, is password-protected, was created by the MERGE command, and has been processed by XCOPY.

CA Disk keeps track of the number of feet on a tape and the number of tracks on disk that have been used by the archiving process. When the size of the next data set to be archived will not fit in the remainder of the archvols data set, the archvols data set is closed and a new one allocated. The data set being archived is then written as the first data set in the new archvols data set. If a data set being archived is too large for the space on a single output volume, multiple output volumes are used. In such a case, the entry for the first volume indicates the number of volumes (in the VOL CNT FIELD), and chains the additional volumes together using their key fields.

The sequence number (SEQ NBR) is incremented for each volume in the chain.
