PROBLEM: sas_address sysfs attribute empty on E208i-p SR Gen10

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The sas_address device attribute in sas_device sysfs in is 0x0, and
missing (empty or null?) in scsi_disk sysfs on LTS kernel 5.10.x, and
Stable 5.13.1

Specifically  /sys/class/scsi_disk/X:X/device/sas_address and
/sys/class/sas_device/end_device-X:X/sas_address are null and 0x0
respectively

Using this device in hba mode (pass through) - Serial Attached SCSI
controller: Adaptec Smart Storage PQI 12G SAS/PCIe 3 (rev 01)
Subsystem: Hewlett-Packard Company Smart Array E208i-p SR Gen10

This appears to have regressed some time after 4.19 (expected results
from 4.19 below)

It seems that systemd udev depends on this attribute from sysfs to
populate /dev/disk/by-path, and when it is unavailable the sas_address
shows as 0x0, which breaks population of this directory, potentially
breaking userspace tools that rely on this

==================================================================
udevadm uses 0x0 for the address variable of ID_PATH, causing unique
disks to have the same identifier used for ID_PATH, which breaks
population of /dev/disk/by-path

[bryce@myhost ~]$ udevadm info /dev/sdy | grep "ID_PATH=""
E: ID_PATH=pci-0000:5c:00.0-sas-0x0000000000000000-lun-0

[bryce@myhost ~]$ udevadm info /dev/sdx | grep "ID_PATH=""
E: ID_PATH=pci-0000:5c:00.0-sas-0x0000000000000000-lun-0

you can see the above 2 disks, should have a unique ID_PATH, and do not.


==================================================================
In kernel sysfs, we see empty sas_address attribute for each disk
attached to the hba in the scsi_disk sysfs
