Summary of Tapes By DSN Group Object

The CA 1 summary of tapes By DSN Group object shows a summary of active tapes grouped by data set name. Tapes are grouped based upon the first data set name written on the tape. The CA 1 Tape Volume record accounts for all DSNBs on a tape. The CA 1 TMC controls all of the tapes in the summary. The CA 1 Tape Volume unfiltered records provide input to this summary.

Note: Secondary DSNBs do not influence the assignment of a tape to its data set group, but the space they occupy is included in the totals.

This summary is organized by filters defined in the CA Vantage parmlib data set member FILTVITD. Update member FILTVITD to use the DSN groupings in effect at your site.

For each group of tapes (as defined in <parmlibMember>), this object creates one summary record containing:

• Group name
• Number of tapes in the group
• Percent of the total the group represents
• Total allocated MB
• Average, minimum, and maximum allocated space for the tape in that group

In addition, this table shows the average, minimum, and maximum values for the total number of:

• DSNBs on the selected tapes
• Opens for all the tapes in the group
• Tape blocks on all the tapes in the group
