Detail

Use the detail with the query vm command to display the following statistics:

• The average number of IBM Storage Protect objects that are needed to describe a single megablock, across all megablocks in a backup.
• The average number of IBM Storage Protect objects that are needed to describe a single megablock, for all megablocks in a filespace.
• The number of backups that were created since the last full backup was created from the production disks.

The values returned on query vm can help you fine tune the heuristics (see the Mbobjrefreshthresh and Mbpctrefreshthresh options) to fine tune the values trigger for megablock refreshes.
