|---|---|---|---|---|---|
| 0 | 0 | 9 | binary | VPS Message Header data | |
| 9 | 9 | SMF94S2_LIBID | 3 | binary | Library Sequence Number |
| 12 | C | 2 | binary | Reserved (set to X'00'). | |
| 14 | E | SMF94S2_HHI | 2 | binary | Hour Index. The hour index is incremented once each hour by the library manager. It is used to prevent duplicate logged statistics from the same one hour period from being counted twice. The hour index for volume pooling statistics is the same as reported for library statistical data calculated for the same hour. |
| 16 | 10 | SMF94S2_LRTD | 10 | EBCDIC | Last Reconcile Time and Date. This 10 EBCDIC character field contains the last time and date a reconcile was automatically completed by the VTS. Some of the statistical fields are calculated at this point. |
| 26 | 1A | SMF94S2_MNVP | 2 | binary | Maximum number of volume pools allowed in the partition This 2 byte hexadecimal field contains the maximum number of volume pools allowed in the partition. The number begins with 1. This field is used by the host to determine if there are more than 16 volume pools which would require additional requests for statistical data. |
| 28 | 1C | 1 | binary | Reserved (set to X'00'). | |
| 29 | 1D | SMF94S2_VPSET | 1 | binary | Volume Pool Set. This byte specifies which set of volume pools are being reported, based on the set requested in the preceding request. If the set specified is 0, the first 16 volume pools are reported, if 1, the next 16 and so on. |
| 30 | 1E | 2 | binary | Reserved (set to X'00'). | |
| 32 | 20 | 1 | binary | Reserved (set to X'00'). | |
| 33 | 21 | SMF94S2_BPMIO | 1 | binary | Common Scratch Pool Media Identifier 0. This
one byte field contains the identifier for the media type associated
with the following common scratch pool volume
count. The following are the defined values for this field:
|
| 34 | 22 | SMF94S2_BPSVCO | 2 | binary | Common Scratch Pool Stacked Volume Count - Media
Identifier 0 (Hourly Snapshot) This two byte field contains the number of scratch stacked volumes, of a type identified by Media Identifier 0, assigned to the common volume pool. The number is updated periodically within the VTS and the reported value is the snapshot of that count when statistics are calculated at the end of the last hour. Physical volumes are assigned to the common scratch pool upon entry into the library or when returned from being borrowed by another pool. |
| 36 | 24 | 1 | binary | Reserved (set to X'00'). | |
| 37 | 25 | SMF94S2_BPMI1 | 1 | binary | Common Scratch Pool Media Identifier 1 This one byte field contains the identifier for the media type associated with the following common scratch pool volume count. See the Common Scratch Pool Media Identifier 0 field for the values defined for this field. |
| 38 | 26 | SMF94S2_BPSVC1 | 2 | binary | Common Scratch Pool Stacked Volume Count - Media
Identifier 1 (Hourly Snapshot) This two byte field contains the number of scratch stacked volumes, of a type identified by Media Identifier 1, assigned to the common volume pool. The number is updated periodically within the VTS and the reported value is the snapshot of that count when statistics are calculated at the end of the last hour. Physical volumes are assigned to the common scratch pool upon entry into the library or when returned from being borrowed by another pool. |
| 40 | 28 | 1 | binary | Reserved (set to X'00' | |
| 41 | 29 | SMF94S2_BPMI2 | 1 | binary | Common Scratch Pool Media Identifier 2 This one byte field contains the identifier for the media type associated with the following common scratch pool volume count. See the Common Scratch Pool Media Identifier 0 field for the values defined for this field. |
| 42 | 2A | SMF94S2_BPSVC2 | 2 | binary | Common Scratch Pool Stacked Volume Count - Media
Identifier 2 (Hourly Snapshot) This two byte field contains the number of scratch stacked volumes, of a type identified by Media Identifier 2, assigned to the common volume pool. The number is updated periodically within the VTS and the reported value is the snapshot of that count when statistics are calculated at the end of the last hour. Physical volumes are assigned to the common scratch pool upon entry into the library or when returned from being borrowed by another pool. |
| 44 | 2C | 1 | binary | Reserved (set to X'00'). | |
| 45 | 2D | SMF94S2_BPMI3 | 1 | binary | Common Scratch Pool Media Identifier 3 This one byte field contains the identifier for the media type associated with the following common scratch pool volume count. See the Common Scratch Pool Media Identifier 0 field for the values defined for this field. |
| 46 | 2E | SMF94S2_SVC3 | 2 | binary | Common Scratch Pool Stacked Volume Count - Media
ID 3 (Hourly Snapshot) This two byte field contains the number of scratch stacked volumes, of a type identified by Media Identifier 3, assigned to the common volume pool. The number is updated periodically within the VTS and the reported value is the snapshot of that count when statistics are calculated at the end of the last hour. Physical volumes are assigned to the common scratch pool upon entry into the library or when returned from being borrowed by another pool. |
| 48 | 30 | SMF92S2_ARRAY | 1792 | binary | Volume Pool Statistics array. Each entry contains information about the usage and characteristics of a volume pool. Each entry in the array is 112 bytes long and is mapped by SMF94S2_ARRAY_ENTRY. Up to 16 array entries may be present. SMF94S2_MNVP contains the maximum number of pools in the library partition. When there are more than 16 pools, additional Volume Pool Statistics sections will be recorded. The number of Volume Pool Statistics sections is indicated by SMF94S2_SON in the self-defining section. |
