The Disk Utilization section of the System Report shows the utilization for each disk.
Changes to this section of the System Report include:
- The "ASP Rsc Name" and "ASP ID" columns have been removed.
- A label has been added at the beginning of each ASP/IASP section that indicates the ASP ID and ASP Rsc Name. The ASP Rsc Name is printed only when the DSASPN (ASP resource name) field in the QAPMDISK database file contains data.
- Totals and averages for each ASP/IASP section are printed at the end of each group of ASP/IASP.
- Totals and averages for all disk units are printed at the end of the Disk Utilization section, as before.
