DDL Record for DEVICE Entities (Legacy Style)
The Legacy Style DDL record for DEVICE entities will not change after the Measure G10 PVU.
The fields included in BRIEF reports are in boldface type (requests appears only in G-series brief
reports).
The DDL record for G-series and later DEVICE entities is identical to the record for D-series DEVICE
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 devices 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 also 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. In H-series and J-series RVUs, all
byte-count fields have 64 bits. For information on using the 64-bit fields, see Usage Note for
G-Series DEVICE Entities (page 188).
• The ERROR field can signal a field overflow in a 32-bit byte-count field.
