P: Program Flash
Command:
P
Syntax:
P
Purpose:
Program Flash. This command allows a user to download
new sector 0 monitor microcode or new runtime microcode
to the controller, which reprograms the controller’s flash
memory. The controller knows which sectors to program
based on the downloaded code’s file type. The microcode
can be downloaded using the file transfer capability of
Windows Terminal or Procomm Plus. The new microcode
does not get executed until the box is power-cycled or soft-
reset using the monitor’s RST command. To abort a
download, you must stop the file download (how this is
done depends on the program), then press <esc> to tell
the monitor to cancel the download. Once the download is
complete, there is no way of stopping the flash from
programming. Turning off power while the flash is
programming can put the controller in an unrecoverable
state so don’t do it. There is a faster, easier method of
loading new SCSI Switch controller microcode via the IPL
6790E or IBM 3490E-11 tape drive.
Examples:
Done using the Procomm communications package.
At the monitor prompt, enter P.
