Murali,
Map names in the shell are like "FS0" or "FS1" and represent each file system.
Unless you need to do raw writing, it's a lot easier to let the other
drivers/applications help you.
I would use ShellProtocol functions:
GetDevicePathFromMap() (for each map item)
Then determine which device path has the SCSI node that you are interested in.
Use DevicePathLib to help enumerate through the path provided.
And the ShellLib functions:
ShellOpenFileByName () (make up any filename starting with the map you
specified above).
ShellWriteFile
ShellCloseFile
Will help you write data.

Hi Jaben,
<Jaben> Is there a reason that you are writing a drive and not a UEFI Shell
application?
<Murali> I don't have any specific reason.Please help on my query?

Are you planning to write a UEFI Shell Application, UEFI Application (without
shell), or a UEFI Driver?
There are many possible methods to do what you're trying to do.

Dell - Internal Use - Confidential
Hi All,
I need to search the SCSI in system and then want to write some data on HDD.
Can anybody help me how to proceed with that.
Some idea I have like
1- From gBS openprotocol for scsi
2- Then get device type
Required
1- How to get HDD ID to select particular HDD to write ?
2- How to select particular block to write ?
3- How to read back the data ?
Best Regards,
Parmeshwr Prasad

Hi All,
My intel board has multiple PCIe slots,one of slots connected with PCI
Express to 4-Port Serial Attached SCSIController.On this SAS controller
I have connected three SCSI devices from the on board SAS slots.
I need to write a driver which will display the connected scsi devices with
the following information.
1) Device Type 2) Size of the Hard disk
Query:
1) Do I need to implement SCSI host controller driver or SCSI bus driver
or SCSI device driver?
2) Do I need to implement PCI root bridge driver or PCI bus driver or PCI
driver?
3) My driver will load from EFI shell <efi shell> load driver.efi
The output should display the connected end devices list with the above
information.
4) Please suggests me how to start to implement with any reference code
with respect to my requirement.
Thanks
Murali.S
