uboot reports adding disk failed(EFI_NOT_FOUND) and first disk is gone in next scsi scan

[Hongxing Zhu]

Hi Simon:
I found that the EFI complained that the disk install path is not updated for the second disk.
The install path is “EFI: installed device path '/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Scsi(0,0)'”
when first disk is added.

But the path is same when the second or later disks are added, and EFI repors that the path had been installed already.
EFI: Path /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Scsi(0,0) already installed

That’s why the below error when run efi_disk_create_raw() function.
Adding disk for ahci_scsi.id0lun0 failed (err=-9223372036854775788/0x8000000000000014)

Do you have any clues about this?
Thanks in advanced.

Best Regards
Richard Zhu

Hi Simon:
Nice to meet you.
The u-boot I used is based on v2023.04 tagged version.
Layerscape LX2160A RDB board has four SATA controllers.
Based on LX2160A RDB board and two or more SATA disks connected.
I encounter one “scsi scan” problem.

After the first SATA disk is detected and probed properly in the first “scsi scan”.
The other disks would complain that “EFI_NOT_FOUND” error listed below,
when run the first “scsi scan” command in uboot environment.
Does this error matter?
BTW, “scsi info” says that all disk info can be dumped, and all disks are works well,
after the first “scsi scan”

In the consecutive rescan operations issued by “scsi reset” or “scsi scan” commends,
the disks would report “unable to unbind devices (-1E)” error.
The first disk is disappeared at all after the next “scsi scan” operations is finished.

Did you used to encounter such kind of issue?

Any suggestions and guidance are very appreciated.
