We met the issue DM complains that it can't find the disk specified in the deployment config file after we updated the Linux kernel to 5.10. The error is "failed to find disk for path /dev/disk/by-path/ pci-0000:3b:00.0-sas-0x31402ec001d92983-lun-0" This happens because device type SATA is excluded from being processed with the function pqi_is_device_with_sas_address. which causes all SATA type disk drives to appear the same, having zeroes in the lun name. /dev/disk/by-path/ pci-0000:3b:00.0-sas-0x0000000000000000-lun-0 We can add type SA_DEVICE_TYPE_SATA to class device_with_sas_address, since it will also get the sas_address from wwid. and works transparently with the old kernel without gaps. Successfully installed on Wind River lab ml350_g10 which contains a P816i-a SR Gen10 disk controller. This lab previously exhibited the problem.

Subject: [PATCH] scsi: smartpqi: Enable sas_address sysfs for SATA device
|
|
type.
|
|
|
|
We met the issue DM complains that it can't find the disk specified
|
|
in the deployment config file after we updated the Linux kernel to 5.10.
|
|
The error is "failed to find disk for path /dev/disk/by-path/
|
|
pci-0000:3b:00.0-sas-0x31402ec001d92983-lun-0"
|
|
|
|
This happens because device type SATA is excluded from being
|
|
processed with the function pqi_is_device_with_sas_address.
|
|
which causes all SATA type disk drives to appear the same, having
|
|
zeroes in the lun name. /dev/disk/by-path/
|
|
pci-0000:3b:00.0-sas-0x0000000000000000-lun-0
|
|
|
|
We can add type SA_DEVICE_TYPE_SATA to class device_with_sas_address,
|
|
since it will also get the sas_address from wwid. and works transparently
|
|
with the old kernel without gaps.
