Best approach for using sg_ses to control locate/fault leds?

[Jeff Johnson <jeff.johnson@aeoncomputing.com>]

Greetings,

     I am using sg_ses to poll a SAS JBOD for locate and fault led 
status and light leds if needed. So far the only method I can figure out 
how to accomplish this is by reading page 2 of the SES management device 
in the jbod chassis, dumping the raw hex output to a file, setting the 
select and RQST IDENT or RQST FAULT bits and sending back the entire 480 
bytes with modified bits.

Turn locate led on:
sg_ses --page=0x2 /dev/sg18 -f --raw > /tmp/out
...twittle bits in /tmp/out with editor of choice...
sg_ses --control --page=2 -d - /dev/sg18 < /tmp/out

     Is there a utility, a '--element=' arg or another method by which 
only the four bytes of the element control diag page can be sent instead 
of all 480 bytes?
