Mode Sense (1Ah) 2
The SCSI Mode Sense command provides a general method for a host to
obtain current parameter settings of a target device. The host selects the
set parameters to be returned by setting the Page Code field in the
command block. This code selects the page of parameter information to
be returned by the target.
The DX-Series system supports the three medium changer device
parameter pages defined in the SCSI-2 specification and two vendor
unique pages:
• Element Address Assignment Page
• Transport Geometry Parameters Page
• Device Capabilities Page
• Vendor Unique Page 20h
• Vendor Unique Page 00h
The host can request all pages with a single command using the Return
All Pages page code as described in the SCSI-2 specification.
The format for the Mode Sense command block is shown in table 30.
