9.3.1.1
Inquiry Vital Product Data pages
Instead of the Standard Inquiry data shown in Table 6, the initiator can request several Vital Product Data
pages by setting the Inquiry command EVPD bit to one. The
SCSI Interface Product Manual,
part number
77738479, section 5.1.1.3.1 lists the Vital Product Data pages supported and describes their formats. A sepa-
rate Inquiry command must be sent to the drive for each Vital Product Data page the initiator wants the drive to
send back.
9.3.2
Mode Sense data
The Mode Sense command provides a means for the drive to report its operating parameters to the initiator.
The drive maintains four sets of mode parameters: default values, saved values, current values and change-
able values.
Default values are hard-coded in the drive firmware that is stored in flash EPROM nonvolatile memory on the
drive PCB. Default values can be changed only by downloading a complete set of new firmware into the flash
EPROM. An initiator can request and receive from the drive a list of default values and use those in a Mode
Select command to set up new current and saved values, where the values are changeable.
Saved values are stored on the disk media using a Mode Select command. Only parameter values that are
allowed to be changed can be changed by this method. “Changeable values” are defined below. Parameters in
the saved values list that are not changeable by the Mode Select command get their values from the default
values storage.
