Vendor-Unique SCSI Information
MODE SENSE Flash Memory Configuration Page (30
Product Manual
You use the MODE SENSE Flash Memory Configuration page to determine the
user information currently configured for the drive.
A drive with HW=1 (that is, that uses DIP switch settings) does not use most of the
settings shown unless reprogrammed to the "use flash memory" setting. A drive
needs to be programmed in another parameter (HW field) to use the flash memory
configuration over the DIP switches, if it has been set previously to use DIP
switches.
The following table shows the layout of the fields of the MODE SENSE Flash
Memory Configuration Page.
