Can not enable Dynamic Storage Accelerator via CLI (14.8.0.1042)

Hello.

In connection to this /thread/100159 tread. I still can't solve the issue (BIOS updated since then, Windows updated since then, tried NUC 14.10.0.1016 driver and software, but no luck anyway).

In short: I got i7-4770 on Z97, Windows 10 x64 1086.318, driver and software version of 14.8.0.1042. At some point Dynamic Storage Accelerator stopped working. Did a lot of messing with drivers trying to solve the issue but with no success.

For now I got Dynamic Storage Accelerator enabled in BIOS, I got drivers and RST software installed. But Dynamic Storage Accelerator does not work.

So I tried rst cli (in elevated cmd) in order to investigate the problem:

K:\rstcli>rstcli64 -I

--CONTROLLER INFORMATION--

Name: Intel Chipset SATA RAID Controller

Type: AHCI

Supported RAID: 0,1,5,10

Max Disks/Array: 6

HW Information:

Vendor ID: 0x8086

Device ID: 0x2822

HW Revision: 0

Dynamic Storage Accelerator: Disabled

than I did

K:\rstcli>rstcli64 --dynamic-storage-accelerator true

0

it says executed successfully, but still got

Name: Intel Chipset SATA RAID Controller

Type: AHCI

Supported RAID: 0,1,5,10

Max Disks/Array: 6

HW Information:

Vendor ID: 0x8086

Device ID: 0x2822

HW Revision: 0

Dynamic Storage Accelerator: Disabled

I also tried

K:\rstcli>rstcli64 --dynamic-storage-accelerator false

REQUEST_FAILED: Request is formatted correctly but failed to execute.

Dynamic Storage Accelerator is already Disabled

For some reason it thinks DSA is always off, no matter I force it to switch on.

Why I can not enable DSA? What could be a problem? Is there anyway to solve it without a complete Windows reset/reinstall?

Thanks anyone in advance.

Hello, an error was introduced with version "14.8.0.1042" in the register. So AFTER you activate the DST in the gui menu (or rstCLI) :

go to "regedit"

locate "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorA\Parameters\Device"

and change value : "LakeTinyReg" with dword (32bits) = "00000103" to "LakeTinyReg" with dword = "00010003" :

And after that, You are able to have always active DST on SHUTDOWN, RESTART, HIBERNATION....
