Yes, but it's not the same bug.
I can only check disks status on the first LSI Raid channel (channel 0) :

Guys, while I really appreciate all of the effort that went into making smartmontools able to look at the physical drives behind LSI/PERC RAID controllers, this is a nasty bug, because it's not immediately obvious what's going on. You really don't notice it until you start looking closely at the individual devices. E.g.:

$ smartctl -i -d megaraid,0 /dev/sda | grep Serial
Serial number: 3JR4LK23M

$ smartctl -i -d megaraid,0 /dev/sdb | grep Serial
Serial number: 3JR4LK23M

To make it worse, there is absolutely no warning about this bug whatsoever: it's not mentioned in the man page, it's not mentioned in the CHANGELOG, and it's not even mentioned in the source.

Ideally, this bug could be fixed. (Unfortunately, I've looked briefly at the source code, and it's clear I don't have the necessary driver expertise to track this down and fix it.)

However, in the meantime, please update the documentation to mention this deficiency.

One other thing I'll mention: we have multiple systems (one RHEL4 system, one RHEL5 system) that have multiple PERC controllers in them, and I'm well-practiced in compiling and debugging programs. If there's any way I can assist in debugging this problem, let me know...

  • cc dpgilbert added
  • component changed from smartctl to all

Recent megaraid drivers may require sg or bsd devices to access physical drives (e.g. /dev/sg1 or /dev/bsg/1:0:0:1).

Please provide output of lsscsi -g if possible.

  • owner changed from somebody to samm2
  • status changed from new to assigned

I think i know the reason. Please provide 2 outputs:

# smartctl -id megaraid,0 /dev/sg3 -r ioctl,10
# ls /dev

I can try to fix this bug if my idea is correct.

It seems we have the same bug.

Its possible that we are talking with a wrong device. Could you please send output of the
cat /proc/devices

command?

  Changed 12 months ago by samm2

One more q:

# smartctl -a -d megaraid,22 /dev/sda |grep Model
(Nothing found, HDD is on the second channel)
# smartctl -a -d megaraid,5 /dev/sda |grep Model
Device Model: WDC WD2001FASS-00U0B0

Its unclear for me why are you using /dev/sda for the second controller.

I used /dev/sdc instead of /dev/sda and it works. Thank you! But how can I get correct device path for the device number?

  • status changed from assigned to closed
  • resolution set to wontfix

ok, thank you for reply, so at least smartmontools works correctly.

I think you should get it from lsscsi or dmesg output. Internally device name converted to the
bus number using SCSI_IOCTL_GET_BUS_NUMBER ioctl call.

I stumbled upon this ticket when looking for how to do smartctl on megaraid devices. I have decided to document my findings, hope you find it useful.

I do get S.M.A.R.T information with this command: smartctl -i -d sat+megaraid,2 /dev/sda

If I let the ,2 run through a sequence like from 2-14 I do get individual information about all my 12 disks. The Serial Number is different depending on which ,# I ask about.

However, if I keep the ,# static, like ,2 then it does not make any difference if I ask /dev/sda, /dev/sdb, ..., /dev/sdl or /dev/bsg/* I still get the same disk information sole dependent on the ,# part.

This means I can not use smartctl to correlate which disk is sda, sdb, ..., sdl. But it is possible to use "megacli -LdPdInfo?? -a0" because one of that commands output lines are "Virtual Drive: 11 (Target Id: 11)" which matches the lsscsi output "[0:2:11:0] disk SMC SMC2108 2.12 /dev/sdl". Another megacli output line is "Device Id: 14" which corresponds to the ,14 number above. The serial number from smartctl -i -d sat+megaraid,14 matches with the serial number from both "megacli -LdPdInfo?? -a0" and "megacli -pdInfo -PhysDrv??[$encdeviceid:$slotnr] -a$controllernr".

However, I only have one megaraid controller. lsscsi -g gives no sg devices, lsscsi -H says [0] megaraid_sas. lspci gives 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2108 [Liberator] (rev 05)

It is also possible to lookup the correlating information under /sys.
