Summary by DSN Group Object

The Summary by DSN Group object displays a summary of all active tapes (that is, tapes not in scratch status) grouped by data set name. The CATLMS catalog controls all of the tapes in the summary. The CATLMS Tape Volume records provide input to this summary.

This summary is organized by filters defined in the CA Vantage SRM parmlib data set, member FILTLTD. Update member FILTLTD to use the groupings in effect at your site. The filter selects a tape for the group using the first data set name written on the tape. Secondary files are not used in the assignment of tapes to data groups, but the space they take up is added to the totals.

For each group or dataset name (as defined in FILTLTD), this object creates one summary record containing the following information:

• The group name
• The number of tapes in the group
• The percent of the total the group represents
• The total allocated MB
• The average, minimum and maximum allocated space for the tapes in the group
• The total number of files on the tapes (with average, minimum, and maximum values)
• The total number of opens for all the tapes in the group (with average, minimum, and maximum values)
• The total number of tape blocks on all of the tapes in the group (with average, minimum, and maximum values)

Note: For more information on these fields, see the Help About Object online help.
