There isn't much information about the SMP READ_GPIO and
WRITE_GPIO (and extended variants) in the older SAS
standards and now they have been pushed out of the recent
SAS (SPL-3) drafts. SFF-8485 ain't much help in that
respect either. If anyone has information (not covered by
an NDA) about how these are used, please send it to me.
As for blinking the LED on a SAS disk: in the sdparm package,
in the 'scripts' directory, try the sas_disk_blink script.
