Media Volume Statistics Report (QP1AVU)
The Media Volume Statistics report is produced when you run the command PRTMEDBRM TYPE(*STATISTICS). You can use it periodically to check the usage of your media and identify if any volumes are being used excessively when compared to others.
The following should
be noted about this report:
- The "*" to the right of the Expiration date field indicates that the volume has expired. The "E" indicates that the volume is in error status and the "I" indicates the volume requires initialization.
- The Uses field shows the number of times to which a media volume has been read from or written. When the volume exceeds the Usage threshold value for media in its media class, you should take it out of service and replace it with a newer volume. You can review the Usage threshold value in the Work with Media Classes display.
The following fields are the sizes of the disk files that
were written to or read from tape. You should use these as an approximation
as they do not reflect any data compression or compaction that may
have been performed.
- The Bytes read indicates the number of bytes that are read from the volume since its creation date.
- The Bytes written field indicates the number of bytes that are written to the volume since its creation date.
- The Current bytes written field indicates the number of bytes that are currently written on the media volume.
- The Maximum bytes on volume field indicates the maximum number of bytes that you have written to this tape.
