Unable to get data from SCSI disk on FreeBSD with LSI RAID

After upgrading smartmontools from 5.42 to 6.0 smartd with DEVICESCAN in smartd.conf

smartd -r ioctl,3 -d don't show any ioctls, just:

smartd -r ioctl,2 -d output from version 5.42 is attached.

Some info about hardware:

(pass diveces created by mfip kernel module)

RAID controller - Supermicro SMC2108 (seems to be LSI MegaRAID SAS 9260)

smartd -r ioctl,2 -d output from version 5.42

One more problem on this hardware with smartmontools 6.0 - device type don't detected:

# smartctl -r ioctl,2 -a /dev/pass1

/dev/pass1: Unable to detect device type
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

In 5.42 smarctl work on this hardware.

Regression was probability introduced by the changes for symlink dereferencing (r3472, r3473).

See all changes in os_freebsd.cpp from 5.42 to 6.0.

No it is not caused by this, but by local and incorrect patch in FreeBSD port. Please try version from SVN it should work fine. Don`t forget to report your results.

I have build smartmontools without patch - smartctl now works with pass diveces, but smartd still can't find devices.

[yuzhaninov]

version 6.0, no port patches: smartd -r ioctl,3 -d

[Alex Samorukov]

Device: /dev/pass0, not a disk like device [PDT=0x1f], skip

I think i know whats going on. Could you please try smartctl on this specific device? I think that FreeBSD changing disk type to avoid exporting this pseudo-devices as real (adX) drives and this causing this issue. If you can provide me access to the affected server i can try to do workaround

[yuzhaninov]

version 6.0, no port patches: smartctl -r ioctl,3 -i /dev/pass1

[Alex Samorukov]

initial bug was result of the outdated patch in the FreeBSD port. but also it was found that mfip driver changing PDT value of the device from 00h to 1fh what making problems for smartd/smartctl. Proposed patch to os_freebsd.cpp sent by an email, waiting for feedback.

fixed in r3674
