This section defines the diagnostic codes that are returned by the EXTEND to same volume function of DADSM. These diagnostic codes might be displayed in messages.
If an error occurs, DADSM might issue a message IEC614I, which would contain a return code and a diagnostic code.
In Table 1, the Extend diagnostic code (Extend to same volume only) might appear in an IEC614I message. The abbreviations that are used in Table 1 are defined in Table 2.
