Susha -
Just to make sure: The actual SCSI device would be at:
PciRoot(0x0)/Pci(0x3,0x2)/Pci(0x0,0x0)/Scsi(0x9,0x0)
(without the /HD(1,MBR,0xc64a382f,0x800,0x1749e000), which is the partition on
the disk)
So that would be a different handle.

Subject: [edk2] SCSI Protocols not found
Hi,
We have a drive which shows up as a SCSI device when "map" shell command is
executed.
The device path for the device is as follows:
PciRoot(0x0)/Pci(0x3,0x2)/Pci(0x0,0x0)/Scsi(0x9,0x0)/HD(1,MBR,0xc64a382f,0x800,0x1749e000).
We need to issue SCSI INQUIRY and other SCSI commands to the device.
However, none of the SCSI protocols - EFI_SCSI_IO_PROTOCOL,
EFI_SCSI_PASS_THRU_PROTOCOL, EFI_EXT_SCSI_PASS_THRU_PROTOCOL are found on the
setup when queried using "dh -p " shell command.
Can someone provide input on why the protocols don't exist and how to issue
SCSI commands to the device?
Thanks,
Sushma
