Hello everybody,

I am trying to find the mapping for ata22.00. due to some repeated issues:

# 3.16.36-1+deb8u2~bpo70+1 crazing down
http://paste.debian.net/hidden/54c12fae/

# smart status 16 disks WDC 1TB RE SATA
http://paste.debian.net/hidden/8bfe8d2f/

"[473315.445703] ata22.00: exception Emask 0x0 SAct 0x7fe00007 SErr 0x0 action 0x6 frozen"

lsscsi --verbose doesn’t provide me with the ata details?
http://paste.debian.net/hidden/430599a0/

root@shirley:~# lsscsi --verbose
[0:0:0:0]    disk    ATA      WDC WD1003FBYX-0 1V01  /dev/sdc
dir: /sys/bus/scsi/devices/0:0:0:0 [/sys/devices/pci0000:00/0000:00:1c.0/0000:08:00.0/host0/port-0:0/expander-0:0/port-0:0:0/end_device-0:0:0/target0:0:0/0:0:0:0]

I can not find any useful unique_id with the mvsas driver...
find /sys/devices/pci0000\:00/0000\:00\:1c.0/0000\:08\:00.0/ -iname unique_id

grep ata22 /var/log/messages indicates it is really mapped somewhere...

root@shirley:~# readlink /sys/block/sdm
../devices/pci0000:00/0000:00:1c.0/0000:08:00.0/host0/port-0:0/expander-0:0/port-0:0:10/end_device-0:0:10/target0:0:10/0:0:10:0/block/sdm

Best I came up with with no results:

root@shirley:~# find /sys/devices/pci0000\:00/0000\:00\:1c.0/0000\:08\:00.0/host0/port-0\:0/expander-0\:0/port-0\:0\:10/end_device-0\:0\:10/target0\:0\:10/0\:0\:10\:0/ -type f -exec grep -i ata {} \;

Linux shirley 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.36-1+deb8u2~bpo70+1 (2016-10-19) x86_64 GNU/Linux
root@shirley:~# lsmod mvsas
Usage: lsmod

Thank you in advance!
