dfdutil
dfdutil is a standalone offline utility that downloads firmware to SCSI
devices including disks, arrays, and fibrechannel devices such as SCSI
MUX and fibrechannel arrays.
The firmware image(s) are contained in a Logical Interchange Format
(LIF) volume on the teststation at /spp/firmware/DFDUTIL.LIF. The raw
(usually binary) firmware image of one or more devices is contained in
the LIF filesystem. dfdutil reads this file when it initalizes and
examines header of each file for a standard firmware header. The
firmware header is required for download capability. Since most HP
firmware distributions are already packaged in this format, the
procedure for putting a raw binary firmware image into the proper
format for dfdutil is not covered in this document.
NOTE DFDUTIL.LIF must have read permissions to be accessed by dfdutil.
To load and run dfdutil, enter the following command at the
teststation prompt:
tc_ioutil <node id> dfdutil.fw
This command issues a system reset. The test controller bootstrap loads
the executable image, dfdutil.fw, from the teststation file /spp/firmware/
dfdutil.fw and executes it.
Once started, dfdutil loads the file DFDUTIL.LIF from the teststation
and scans all SCSI and Fibrechannel busses on the system.
