Notes.
** 01 means SCSI-1 implemented;
02 means SCSI-2 implemented. Hawk 2 Family (Wide bus) drives can be changed between these
two configurations. Default is 02.
*** 01 means response data is in SCSI-1 format and has compatibility with Common Command Set
data.
02 means response data is in SCSI-2 format. The drive can be changed between these two configu-
rations. Default is 02. Though the drive supports some "SCSI-3" features, there are no provisions to
indicate this in the Inquiry response data.
( ) Inquiry data reports 01 32 if 16 bit wide address and data bus is used; 00 12 if 8 bit wide address and
data bus is used.
R# Four ASCII digits representing the last four digits of the product Firmware Release number. This
information is also given in the Vital Product Data page C0h, together with servo RAM and ROM
release numbers.
S# Eight ASCII digits representing the eight digits of the product serial number.
D# Four ASCII digits representing the firmware distribution diskette serial number.
[ ] Bytes 18 through 24 will reflect model of drive. Shown here are hex values for ASCII codes repre-
senting “ST12400WD”. Byte 24 is 43 for model ST12400WC.
11.3.1.2 Inquiry Vital Product data
Instead of the standard Inquiry data shown in Table 11.3.1-1, the initiator can request several Vital Product
Data pages by setting the Inquiry command EVDP bit to one. The SCSI-2/SCSI-3, Version 2 Interface Prod-
uct Manual P/N 77738479, Section 5.1.1.3.1 lists the Vital Product Data pages supported and describes their
formats. A separate Inquiry command must be sent to the drive for each Vital Product Data page the initiator
wants the drive to send back.
