Hi all,
I'm trying to manipulate SAS LED state on a nontrivial scale - e.g.
enabling/disabling the locator/fault LED lights on all the devices
attached to a system at the moment, or various programmatic subsets.
I've been using the LSI SAS{2,3}IRCU utilities for this, but that's
not exactly efficient, since it can't batch commands, and it seems to
rescan the bus every time it's run...
I'd like to make use of smp_{read,write}_gpio to manipulate this
state, but when I try this on a recent (~Sep 24) illumos-gate,
commands I expect to work give back:
# ./smp_read_gpio -E -t 3 -c 1 /dev/smp/expd1
Read gpio register enhanced result: Unknown SMP function
# ./smp_read_gpio -t 3 -c 1 /dev/smp/expd1
Read gpio register result: Unknown SMP function
Something like smp_discover seems to work fine:
# ./smp_discover /dev/smp/expd1

Has anyone made use of this toolkit (or another with similar tools?)
successfully on illumos-derived platforms?
I'm probably going to go spelunking in the code to figure out what's
generating this difference in behavior, but before I did that, I
thought I'd ask.
Thanks,
