HI Joe, thanks for the answer.
Unfortunetly, I've writen my previous e-mail wrongly. I have another thas
related to sas in my mind and I did some confusion.
The correct scenario is (re-writing my previous e-mail correctly):
"
*The code is this way now :*
* *
*EFI_STATUS TestMain(EFI_HANDLE ImageHandle, EFI_SYSTEM_TABLE *SystemTable)
{*
* EFI_STATUS Status = EFI_SUCCESS;
EFI_ATA_PASS_THRU_PROTOCOL *ataProtocol;
UINT16 Port;
UINT16 PortMultiplierPort;*
* EFI_HANDLE *HandleBuffer = (EFI_HANDLE *) NULL;*
* UINTN HandleCount = 0;
UINTN HandleIndex = 0;*
* Print(L"*****************\n");
Print(L"*Ata*\n");
Print(L"*****************\n");*
* Status = gBS->LocateHandleBuffer(ByProtocol,
&gEfiAtaPassThruProtocolGuid,
NULL,
&HandleCount,
&HandleBuffer);*
* if (Status == EFI_SUCCESS)
{*
* Print(L"gEfiAtaPassThruProtocolGuid HandleCount: %d\n", HandleCount);*
* // Loop to walk in the handles
for (HandleIndex = 0; HandleIndex < HandleCount; HandleIndex ++)
{
Print(L"HandleIndex: %d\n", HandleIndex);*
* Status = gBS->OpenProtocol(HandleBuffer[HandleIndex],
&gEfiAtaPassThruProtocolGuid,
(VOID **) &ataProtocol,
ImageHandle,
NULL,
EFI_OPEN_PROTOCOL_BY_HANDLE_PROTOCOL);*
* Port = 0xFFFF;
PortMultiplierPort = 0xFFFF;*
* if(EFI_ERROR(Status))
{
Print(L"Status: %x\n", Status);
}
do {
Status = ataProtocol->GetNextPort(ataProtocol,
&Port);*
* if(!EFI_ERROR(Status))
{
Status = ataProtocol->GetNextDevice(ataProtocol,
Port,
&PortMultiplierPort);*
* if(!EFI_ERROR(Status))
{
Print(L"Port: %d\n",Port);
Print(L"PortMultiplierPort: %d\n", PortMultiplierPort);
Print(L"-----------------------------------\n");
}
else
{
Print(L"Status: %x\n", Status);
}
}
else
{
Print(L"Status: %x\n", Status);
}
}while(!EFI_ERROR(Status));
}
}
else
{
Print(L"Status: %x\n", Status);
}
return Status;
}*
* *
* *
*The prints are displaied on the following way:*
* *
******************
*Ata*
*****************
gEfiAtaPassThruProtocolGuid HandleCount: 1
HandleIndex: 0
Status: E*
* *
* *
*The error happen because the the GetNextDevice does not find anything.*
*Any idea about the problem ?*
* *
*As I said before, the code works correctly on a notebook with a SATA hdd,
but don't work on a server with 2 SATA hdds.*
* *
*Thanks and Regards*
* *
*PS.: should the command "dh -p AtaPassThru" return something in my case ?
This command doesn't return nothing. Neither on the server, where the code
does not work, nor on the notebook, where the code works.*
"
Both, the server and the notebook have SATA HDDS. On the notebook the ports
are find, but on the server they are not.
Shoudl the command *dh -p AtaPassThru *return something on the server or on
the notebook ?
Thanks and Regards
