Wanted to leave a big "thank you!" for your plugin. saved my ass (or the money in my pocket :o)) I am using a lsi91214i4e-hba with one sata-hdd and one sas-hdd (ST6000NM0095 - 6TB). It never spun down but the sata-hdd, which is connected to the hba also, did. So i installed your plugin and hoped the best. It took a few restarts and some playing with the automatic spin-down-command (i think), but now the sas-hdd goes into idle: mhttpd: read SMART /dev/sdc Server emhttpd: spinning down /dev/sdc Server SAS Assist v2024.11.25: Spinning down device /dev/sdc yay!
