Re: megaraid + smartctl

Hi,

I have a question regarding MegaRAID and smartctl.


I've a MegaRAID controller and with multiple logical drives (raid1)
created. The devices appear as /dev/{sda,sdb,sdc} to OS and MegaRAID disk
ids as follows.

Logical disk0:          (mapped to /dev/sda)
  physical disk-ID: 9

Logical disk1:          (mapped to /dev/sdb)
  physical disk-ID: 10
  physical disk-ID: 11
  physical disk-ID: 12
  physical disk-ID: 13

Interestingly when I query the disk attributes of each physical disks using
/dev/{sda,sdb}, the results are same.

smartctl -d sat+megaraid,13 -a /dev/sda
smartctl -d sat+megaraid,13 -a /dev/sdb


It seems the device doesn't really indicate anything when working with
MegaRAID as seen above - Let me know if the above assumption is correct or
something wrong with the functioning of smartctl.

I am using smartctl v5.43, latest version v6.2 also reports the same.
