DDL Record for DISC Entities (Legacy Style)
The Legacy Style DDL record for DISC entities will not change after the Measure G10 PVU.
The fields included in BRIEF reports are in boldface type.
The DDL record for G-series DISC entities is identical to the record for D-series DISC entities except:
• The CHANNEL field is redefined to SERVERNET.
• Different entity identification fields are used. The CTRL and UNIT fields are no longer used.
• A SCSI-ID identifier is added to identify disks connected by a ServerNet/DA or FCSA.
• Counters are added to measure busy time in the queue-based ServerNet environment. The
READ-BUSY-TIME and WRITE-BUSY-TIME counters are no longer used.
• Counters are added to measure direct-bulk I/O operations.
• Existing I/O counters such as READS and WRITES include direct-bulk I/O operations.
• Longer byte-count fields are provided to reduce the possibility of field overflow. In G-series
RVUs, each 32-bit byte-count field has a 64-bit counterpart. Similarly, a 16-bit byte count field
has a 32-bit counterpart. In H-series and J-series RVUs, all byte-count fields accommodate 64
bits. For information on using the 64-bit or 32-bit fields, see Usage Notes for G-Series DISC
Entities (page 206).
• The ERROR field can signal a field overflow in a 32-bit byte-count field.
RECORD disc. FILE is "disc" ENTRY-SEQUENCED.
