Description Jan Sarenik 2007-10-10 16:38:13 UTC

Description of problem:

When I run "smartctl -a" by mistake on a SAS storage (mapped as /dev/sda)
attached via LSI Logic SAS based MegaRAID, the system hangs*.

I am not sure whether the bug resides in smartmontools or in the LSI Logic
SAS based MegaRAID driver but I do not want to play with it because
it is on stable server.

* Acually it tries to send the command and after time-out it sets the
  block device /dev/sda to off-line state so I was even not able to
  reboot cleanly (no I/O with /dev/sda was possible)

How reproducible:
  I guess it will work every time I try it.

Steps to Reproduce:
1. smartctl -a /dev/sda #where sda is block device physically connected to
                        #Dell's PERC 5/i.
  
Actual results:


Expected results:
  I would expect smartctl to say "Drive is not supported" or similar.

Additional info:

# cat /proc/scsi/scsi

Comment 1 Tomas Smetana 2007-10-11 17:33:16 UTC

The smartctl program detects certain types of RAID controllers and treats them
specially.  I've prepared a patch that adds the PERC controller type detection.
 When PERC controller is encountered smarctl exits and informs an user that this
device is not supported.
