[ please CC, not on the list ] Hi, I have a bunch of SATA disks hanging off a SAS expander on which I would like to disable APM (using hdparm -B). This doesn't work as-is, and from reading: http://smartmontools.sourceforge.net/smartmontools_scsi.html it appears that I'd need to hack hdparm to use the ATA PASS THROUGH SCSI command to make it talk to SATA disks behind a SAS expander, as was already done for smartctl. Did anyone implement something like this for hdparm yet by any chance?
I need to update that document to state that later versions of hdparm do indeed use the SAT pass-through mechanism and hdparm should work in your situation. So follow Mark Lord's advice.
