How to fix NVMe RAID hibernate failure issue

Question

Hello,
    
   We are developing NVMe RAID StorPort driver and encounter 
 hibernation issue:
 "If the system is booted from our RAID disk, and
 then try to hibernate, the windows only load driver
 for the dummy PCI device as it is booted from the
 dummy PCI device, but the disk is combined by other
 NVME PCI devices which are unavailable, the hibernation
 is failed and system crashed as no disk found."

   When loading our RAID driver for the second time at hibernate, 
 HwFindAdapter routine of dummy PCI device is invoked, 
 but HwFindAdapter routine of NVMe PCI device is not invoked.
     
 Current problem:
   How can we modify the StorPort driver code so that HwFindAdapter   
   routine of the NVMe PCI device is invoked in hibernation?

 Note:
   We try to add power relationship between NVMe PCI device and 
 dummy PCI device, but HwFindAdapter routine of NVMe PCI device
 is still not invoked.

Hello there,

There are two different scenarios of failures that occurs randomly:

-When the hibernation screen goes off, the hard drive works for a few seconds. After that, the hard drive stops working but the PC is still powered on. After powering down by pressing the power button for three seconds and powering on again, Windows starts like a normal clean start, as if it was shut down instead of being hibernated.

-When the hibernation screen goes off, the hard drive works for a few seconds and finally goes STANDBY instead of hibernate.

Try the below steps and see if that helps:

Disable/enable hibernation using powercfg -h tool

Change hibernation file size to 100% of amount of RAM (powercfg -h size 100)

Run deep CHKDSK during system boot

Hope this resolves your Query !!

Hello,

Thanks for your reply.

But my question is to how to adjust driver code to support hibernate.

Could you give some suggestions on this？
