[Smartmontools-support] Brian Lin's questions

[Bruce A. <ba...@gr...>]

Brian,

I apologize for not replying sooner.  There has been some problem with the
mailing list and I have not been getting the mail sent to it.  Hopefully I
willn now have access.

Let me reply to all three postings at once:

> hi   can you tell me why send 1 for enable smart?

use smartctl -e /dev/hda
(or give appropriate device name).  The man page has this as an
example. If you have installed smartmontools on your system, do 
man 8 smartctl
else in the directory where you have installed smartmontools, do
man ./smartctl.8

Please see the "REFERENCES" section on the web page
http://smartmontools.sourceforge.net
and read the man pages above.

I am not much of an expert -- the best I can do is suggest that you read
the code in atacmds.c.  There are twoo different IOCTLs used.  The
HDIO_DRIVE_CMD and HDIO_DRIVE_TASK.  The latter ioctl may be what you
need. Here is the argument order, I think

 unsigned char parms[HDIO_DRIVE_TASK_HDR_SIZE]=
    {WIN_SMART,    // CMD
     SMART_STATUS, // FR
     0,            // NS
     0,            // SC
     normal_cyl_lo,// CL
     normal_cyl_hi,// CH
     0             // SEL
    };

>  can you tell me feature call d7h and dbh for?

Look in the references above, or in atacmds.h, and you'll find:

#define SMART_WRITE_THRESHOLDS  0xd7
#define SMART_AUTO_OFFLINE	0xdb

Cheers,
