WRITEBUF(8)WRITEBUF(8)NAMEwritebuf - write device buffer
SYNOPSISwritebuf-a b.t.l [ -m mode ] [ -b buffer-id ] [ -o buffer-offset ] [
-p plist-len ] -f filename
DESCRIPTION
The writebuf program will send a WRITE BUFFER command to the named SCSI
device. It is typically used to download new microcode to SCSI
devices.
The required -a argument must be used to select a specific ordinal SCSI
address (see libscsi(8)).
The required argument set of -f filename must refer to a file containā
ing the data to write.
OPTIONS-b buffer-id Specifies the identity of the buffer to be written.
-o buffer-offset Specifies the offset from the beginning of the buffer
to begin writing.
-p plist-len Specifies the parameter list length.

The ANSI SCSI-2 specification for more in-depth explanation of the
arguments.
BUGS AND WARNINGS
Some microcode files are large. Be sure that the platform that you run
this command on, and the host adapter that attaches the device to which
you are directing this command, can support sending all of the
microcode in one command. Loading a fraction of the microcode and
failing can be disastrous and can damage a device requiring it to be
sent back to the factory. Use the lusbinfo(8) command and find the I/O
transfer limit size for these constraining factors. Exercise caution
using this command.
