Smartctl open device: /dev/sda [megaraid_disk_01] failed: INQUIRY failed

[Christian Franke]

Recent megaraid drivers may require sg or bsd devices to access physical drives. Please use lsscsi -g to detect appropriate /dev/sgX device. See ticket #46 for further info.

this page showed up in my own search for a solution, so I have decided to leave a note for any future users about what worked for me.

chrfranke's suggested solution, option 'lsscsi -g' did not work for me because I get no sg devices.

But if I change the smartctl type to '-d sat+megaraid,2' 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 ..blabla... ,14 matches with the serial number from both "megacli -LdPdInfo? -a0" and "megacli -pdInfo -PhysDrv?[$encdeviceid:$slotnr] -a$controllernr".

Adding more to jonbendtsen comment.

You will need to do the following:

MegaCli -LdPdInfo -a0 - This shows the "Device ID: XXX"

Run the command and note down the Device ID's.

Once you have all the Device ID's you can finally run your smartctl.

smartctl -S on -a -d megaraid,XXX /dev/sdN

Note: XXX = Device ID Number while N is the corresponding to mount.
