DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi karlrado,

thanks for the advice! It works fine. For everybody else interested:

1. Using the dns323-spindown which is already installed by fun_plug doesn't work (disk starts spinning), because it's on the disk. Just copying to /tmp also doesn't work (probably because it references some libs on the disk). But using the dns323-spindown from http://wolf-u.li/3403/lueftersteuerung- … vision-c1/ on /tmp works fine. The program dns-323-spindown is included in the package uwfancontrol http://ffp.wolf-u.li/additional/ffp-mis … -1.1-4.tgz in folder ffp/var/opt/uwfancontrol/

2.  To interpret the result of dns323-spindown have a look at the source code

data[1] = 2 to get pm support state, return value in data[2]
             return value is bitmask 
             bit 0 set means hd0 supports PM
             bit 1 set means hd1 supports PM

data[1] = 3 to get pm state, return value in data[2]
             return value 1 means at least one drive is active
             return value 2 means all drives spun down

For example

$dns323-spindown
[03] hd0 hd1
[01] ACTIVE

means:
Both disks support power management
at least one disk is active
