You may try:
RESULT="SSEAGATE ST318436LW?3BM07NKA000070456Z6B"
or
RESULT="SSEAGATE ST318436LW*3BM07NKA000070456Z6B"
Please report if it works.

I do not have a patch ready. I found a bug and thought it would be good
to report
It. Once, I have a patch ready, I will surely e-mail it to you as I
have been
Trying fixes for scsi_id.
Hope that works out well for you.

Sorry, I didn't see that you want to use the serial number in
the node name. With the model name prepended it may work,
but sure that's not really the same :)
I will look if I can do something for you with the %c{num} logic.
thanks,
Kay

IMHO, this is a small bug in namedev. Putting ? Or * in result field
does not make
Any difference as the rule will trigger but the string seperator is a
space. The
strsep() function can work of multiple seperators ( line 285 in
namedev.c ) but I
Am not sure by just adding LF to the list of seperators would fix it.

I haven't ever seen a LF in the SCSI vendor, model, or page 0x80. I am not
sure if it is allowed by the standards.
There should be more spaces after the "ST318436LW", since there are 16
bytes for the model and it is space filled ('S' followed by vendor 8
bytes, model 16 bytes, and the serial number of variable size).
Are you certain that rule is matching? Did your editor auto-wrap that
line? i.e. does /sbin/scsi_id -s /block/sda (or whatever the kernel name)
output have a line feed?

I am not sure what the end marker is when /sbin/scsi_id returns. The
strsep()
call is set with space delimitter and the output is "Seagate <model #>
<serial#>"
The end marker would be either a NULL or a LF. The actual part is %c{3}
should
give the serial number as I referred it in NAME="disk-%c{3}" field.

It's not. At least not for page 0x80:
ASCII data fields shall contain only ASCII graphic codes (i.e., code
values 20h through 7Eh) (from SPC-3).
But actually it's not page 0x80 which is the culprit (0x80 returns only
the serial number, which seems to be ok), but rather the model name
(from INQUIRY or page 0x83).
What does the device say at initialisation?
There should be boot messages from the SCSI layer; if something's dodgy
with the data it should show up there, too.
Care to send me the output of dmesg?
Cheers,
Hannes

In working to debug the problem, I got offlist email from Atul (using od,
so the mind numbing line wrapping was not an issue) showing no linefeeds
or such in the model, vendor, or scsi_id output.
