powerd(1M) does it [*] when you setup the system to power down disks when they have been idle for some time (==> configure with the dtpower command). Works only on disks controlled by the sd(7D) driver, so no power management for P-ATA disks on the x86 platform (for p-ata, see the "standby" setting in /kernel/drv/ata.conf). And (IIRC) it doesn't work for USB devices, because scsa2usb filters out scsi start/stop unit commands. [*] actually the sd(7d) kernel driver implements it This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
