[smartmontools-support] FreeBSD: smartctl fails on SAS disk connected to an Intel C600 controller (isci driver)

[Federico S. W. <fe...@te...>]

Hi,

Two months ago I sent the following bug report to the freebsd-bugs list 
but I'm not really sure if the issue is in the isci driver or in 
smartmontools. The affected disks do work on smartmontools for Linux.

Anyway, sorry for cross-posting.

Regards,
Federico Simmross.




The command 'smartctl -i /dev/da0' (where da0 is a SAS disk) fails with 
the following error:

  Apparently this does not happen with a SATA disk connected to the same 
controller.

  The command 'smartctl -T permissive -a /dev/da0' does show the rest of 
the information (see below); however, scripts that look for the string 
'SMART is: enabled' cannot work even with this workaround.
