IXMAINT

A parameter PRIMARY2 for the DSNDELETE command indicates whether the P2 records (both DSNINDEX and ARCHVOLS) are to be processed. The values that can be specified are:

• YES—The P2 records are processed as individual records (default)
• NO—The P2 records are not processed

ONLY—Only the P2 records are processed

By default, IXMAINT treats P2 DSNINDEX records as individual records (for example, data sets can be expired from P2 volumes without affecting any P1 data sets or volumes) except in COPY processing. In COPY processing, if IXMAINT deletes the P1 record, the P2 record is also deleted. COPY processes are: the COPIES parameter on the DSNDELETE command; SMS backup copies and SMS GDG copies.

Using the following example:

DSNDELETE COPIES=5

If there are six pairs of P1 and P2 DSNINDEX records, the oldest pair is deleted. If there are only four pairs, none are deleted.
