HDD Hibernation in DSM 7.1 update 4 not working(Custom Hardware DVA3221 )

[dookei]

Hi there,
I installed in the past  2 old NASs with DSM 7.1 (with tinycore redpill) which have been working for months now, without any issues.
I would like now to install it on a desktop pc(that I have laying around for some years) that still has some power in it and replace a small and slow 1-bay Synology nas
The hardware:

• Asus motherboard Z97(up to 12 SATA drives can be connected)
• Core i7-4790K (4.0Ghz)
• 32 Gb RAM
• 4x 1Tb harddrives( I will be hadding more drives with higher capacity (4Tb) once the systems is running)
• 3x 500Gb SSD(maybe use it for cache)
• 1x GeFORCE GTX 770

 

Installation Steps

• Flash tinycore on a usb stick

• boot the tiny-core and bring a terminal up

• ./rploader.sh update now

• ./rploader.sh fullupgrade now

• ./rploader.sh serialgen DVA3221 realmac

• ./rploader.sh identifyusb now

• ./rploader.sh satamap now

• ./rploader.sh backup now

• ./rploader.sh build denverton-7.1.0-42661

• sudo reboot

• I am able to find the NAS with http://find.synology.com/

• Then I download the pat image https://www.synology.com/en-global/support/download/DVA3221?version=7.1#system](https://www.synology.com/en-global/support/download/DVA3221?version=7.1#system)**

Now the system is running stable for some weeks now. The only issue I am facing is with power management.

I would like to put the hdd to hibernate in order to save some power ... and even turn the system off when not being used longer than 2 hours.

Where should I been looking for?
