Volume usage reports
All volumes are reported on that have data recorded in the snapshots selected. Three different types of reports can be generated by using the Volume report name verb:
The Volume Snapshot report details volume usage for all volumes for a specific snapshot.
The Volume Snapshot report for a specific volume lists volume space usage for a specific volume for one or more snapshots.
The Volume Interval report lists volume space usage for a specific volume averaging the snapshot information on a daily, weekly, or monthly basis. Using the DAY, WEEK, or MONTH keyword switches from Snapshot to Interval reports.
| Purpose | Reports on DASD utilization by volume |
|---|---|
| Data source | Volume database (SGRDVOL) |
| Initial order | Time in descending order |
| Report name verb | VOLUME |
| Member name | SRMBR020 |
See the Report filters and option keywords for space reports for a list of the report option keywords that are available on this report. If the NAME option keyword is used on the VOLUME report, LASTHRS, LASTDAYS, or START is required.
To show data only from weekdays, weekends, specific days of the week, specific days of the month, or a portion of a day, use the SHIFT command to define which snapshots to include in the report. This permits you to generate reports only for weekdays, weekends, first shift, and so on. If you do not specify DAY, WEEK, or MONTH, a Volume Snapshot report is generated. The Volume Snapshot report contains a different set of columns than does the Volume Interval report.
Refer to the field list chart for a detailed listing of all columns displayed. There are separate tables: one for the Volume Snapshot report and another for the Volume Interval report.
Some of the fields listed are not included automatically in the report. If you want to include their contents, use the ORDER command.
The following table presents a field list for the Volume Snapshot Report.
Field list for the Volume Snapshot Report
Column heading | Field name | Description |
|---|---|---|
DATE | DATE | Date the snapshot was recorded. |
TIME | TIME | Time of day the snapshot was recorded in the 24-hour format. |
VOLNAME | VOLNAME | Volume serial name. |
POOL NAME | POOLNAME | Name of the first pool encountered that the volume belongs to. |
POOL TYPE | POOLTYPE | Type of pool that POOLNAME is. |
DEV ADR | DEVADDR | Hexadecimal Device address (UCB). |
DEV TYPE | DEVTYPE | Type of disk device. |
% FULL | PERCFULL | Percentage full of the volume at the time the snapshot was recorded. |
VISUAL | VISUAL | A visual representation of PERCFULL. This column cannot be filtered or sorted on. |
TOTAL SPACE | TOTSPACE | Total available space of all volumes in the space collector database. |
ALOC SPACE | ALOCSPAC | Total space allocated to data sets. This value includes all PO, PS, VSAM, and other data sets combined. |
USED SPACE | USEDSPAC | Total space actually being used. This value is a subset of allocated space (ALOCSPAC) indicating the amount of allocated space actually in use. |
FREE SPACE | FREESPAC | Total unallocated space available. |
IDLE SPACE | IDLESPAC | Total amount of allocated but unused space. This is a good indicator of the amount of storage that is being wasted through over allocation. |
PO SPACE | POSPACE | Total amount of storage allocated to PDSs and PDSEs. |
PS SPACE | PSSPACE | Total amount of storage allocated to sequential (PS) data sets. |
VSAM SPACE | VSAMSPAC | Total amount of storage allocated to VSAM data sets. This includes all forms of VSAM data sets, including both data and index components. |
INDX VTOC | INDXVTOC | Indexed VTOC indicator.
|
SMS INDC | SMSINDC | SMS indicator. N indicates that the volume is not SMS-managed. I indicates that the volume is in SMS Initial status. Y indicates that the volume is SMS-managed. When a pack is SMS-managed and a construct has not been defined for it, the SMS indicator is YES and the SMS status is NO STAT (no status). |
MNT | MNT | Mount indicator. PRV indicates that the volume was mounted as a private volume. STG indicates a storage volume. PUB indicates a publicly mounted volume. |
TCAC | TCAC | Track-level caching. A indicates that track-level caching was active for the volume at the time the snapshot was recorded. I – indicates inactive. |
DCOP | DCOP | Dual copy. A indicates that dual copy was active for the volume. I – indicates inactive. |
CFW | CFW | Cache Fast Write. A indicates that the Cache Fast Write facility was active for the volume. I – indicates inactive. |
FSW | FSW | Fast Write. A indicates that the Fast Write facility was active for this volume. I – indicates inactive. |
FREE DSCB | FREEDSCB | Number of free DSCBs (format 0) that is available in the VTOC. |
FREE VIRS | FREEVIRS | Number of free VIRs that is available. |
FRAG INDEX | FRAGINDX | Fragmentation Index for the volume. |

The following example shows how to generate a report to determine when space utilization on a specific volume exceeded a given percentage.
In this example:
NAME report option keyword requests information for volume WORK03.
LASTDAYS report option keyword limits the request to the last 7 days.
PERCFULL data output field name limits the request to snapshots where the percentage full exceeded 99 percent
VOLUME,
NAME(WORK03),
LASTDAYS(7),
PERCFULL(>99)The following figure provides a sample of the customized report.
