12.6.8 Device Behavior page (C3h)
The Device Behavior page (VPD page C3h) is used by regression tests to determine what behavior should be
expected from a particular firmware package.
Field definitions (listed alphabetically)
ASCII Model Number
Identical to the Product Identification Number given in the standard Inquiry command data (see Table 105).
Behavior Code and Behavior Code Version Number
Jointly assigned by the Firmware Engineering Managers of all SCSI design locations.
Default Number of Cache Segments
Identical to the same parameter given in the Mode Caching page (see Table 152).
Feature flags and additional byte fields...
These bytes are not yet defined.
Maximum Interleave
The maximum value which the drive can support in the least significant byte of Interleave in the Format Unit command (see
Table 96). The actual interleave which has been used during the last Format, providing it has not been changed by an inter-
vening Mode Select command is reported in the Interleave bytes of the Format Device bytes of the Format Device page
(see Table 149).
Page Code
C3h Provides the behavior code information for the drive.
Page Length
32h The length of the Device Behavior page (in bytes).
Peripheral Qualifier and Peripheral Device Type
00h A direct-access device (magnetic disc) is connected to this logical unit.
Version Number
A 1-byte short form notation for the 24-byte assignment in the Firmware Numbers page. Version Numbers are registered by
engineering services.
