[smartmontools-support] Problems talking to disks behind PERC adapter

[mathog]

Hi,

smartctl talks happily to disks on several machines with PERC adapaters
here, but one it does not like. megacli says that the adapter on this
Centos 6.9 machine is:

However the smartctl which comes with Centos 6.9 will not talk to it:
smartctl -i /dev/sda -d sat+megaraid,0
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-573.22.1.el6.x86_64]
(local build)

Smartctl: Device Read Identity Failed: megasas_cmd result: 0.0 = 0/45

smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device


and neither will one just built from scratch:

./smartctl -i /dev/sda -d sat+megaraid,0
smartctl 6.5 2016-05-07 r4318 [x86_64-linux-2.6.32-573.22.1.el6.x86_64]

/dev/bus/0 -d megaraid,7 # /dev/bus/0 [megaraid_disk_07], SCSI device


Suggestions?

Figured it out, the syntax needed is:

smartctl -a /dev/sda -d megaraid,0

the other machines have a "sat+" immediately before the megaraid. These
don't, probably because the disks are SAS.
