I'm working on a web-interface for FreeBSD+ZFS. This interface allow users to manage ZFS and one of the things I'm currently working on is spinning down disks and up again, setting APM (Advanced Power Management) and AAM (Automatic Acoustic Management).
I currently know how to:
- Spin down a disk, and spin it up again
- Set APM using custom camcontrol cmd command
- Set AAM using custom camcontrol cmd command
- Use camcontrol identify to know whether APM is supported
- Inquire whether a disk is currently spinned down or not
- Inquire the current APM and AAM setting of a disk
- Inquire whether AAM is supported or not (camcontrol identify does not list this feature)
