00:16:07 <swinokur> rmustacc: gotchas - you had asked for other documentation yesterday I guess I thought that the freebsd bit might be what you were looking for, but perhaps not? 
07:01:10 <rmustacc> swinokur: No, I'll need to go back to the actual MPI docs.
18:54:32 <swinokur> rmustacc: not sure if this helps, but I just found this on github: https://github.com/thomaslovell/LSIUtil/tree/master (it has solaris binaries and makefile). It runs on my system, and using menu #9 (get/set configuration pages), I can see the data from "page 7" (which based on the truenas link, is where the temperature is kept)? I thought this might help you put something together! thanks again for being willing to look into this!
18:59:49 <swinokur> oh yes, looks like someone on reddit might have solved it using a bit of scripting around that command: https://old.reddit.com/r/homelab/comments/cqvxeb/monitoring_the_status_of_a_92118i_hba_in_itmode/
19:00:35 <swinokur> echo $(( 16#$( ./lsiutil.i386 -p2 -a 25,2,0,0 | grep IOCTemperature: | cut -dx -f2 ) )) ... returns "52"
