Hi. I'm using two SIIG eSATA II PCIe PRO adapters on a Sun Ultra 24 workstation, too. The adapters are connected to four external eSATA drives that made up a zpool used for scheduled back-up purposes. I'm now running SXCE b129, live upgraded from b116. Before the live upgrade the external disks were spinning down when idle, now they never do. /etc/power.conf was not modified. I'm probably waiting the next OpenSolaris release and check if it works. Nevertheless, in the meanwhile, do you have any suggestion about how to debug this? I don't like wasting energy this way and I cannot shutdown that machine so often.
