In my limited knowledges about hobbit and NCV module (i don't have any C 
or system low level skills), you can get multiple files in formating 
your test output like this :

your text
anything you want
....
lun0_input : value1
lun0_output : value2
lun1_input : value3
lun1_output : value4
NEW LINE CHARACTER


So you can define your hobbitserver.cvf as it :
SPLITNCV_lun="*:GAUGE" (or any other RRD data type)
GRAPHS="...,lun0,lun1,lun2..."

You'll have several RRD files, named like this :
lun,lun0_input.rrd
lun,lun0_ouput.rrd
lun,lun1_input.rrd
...
then you can define hobbitgraph.cfg as I did :
[lun]
         FNPATTERN lun,(.*).rrd
         TITLE LUNs IOS
         YAXIS IOS
         DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE
         LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@
         GPRINT:p at RRDIDX@:LAST: \: %5.1lf (cur)
         GPRINT:p at RRDIDX@:MAX: \: %5.1lf (max)
         GPRINT:p at RRDIDX@:MIN: \: %5.1lf (min)
         GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

You can define per lun graphs :

[lun0]
	FNPATTERN lun,lun0(.*).rrd
         TITLE LUN0 IOS
         YAXIS IOS
         DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE
         LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@
         GPRINT:p at RRDIDX@:LAST: \: %5.1lf (cur)
         GPRINT:p at RRDIDX@:MAX: \: %5.1lf (max)
         GPRINT:p at RRDIDX@:MIN: \: %5.1lf (min)
         GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

in bb-hosts, define :
IP.AD.DR.ESS hostname # TRENDS:*,lun0,lun1...

So, you'll have a global graph including all LUNs IOS, drawed when you 
click lun test.
And you'll have several lun0, lun1 ... graphs drawed in trends.

If that's not the result you'd like, please be more specific (and don't 
forget I'm french, so I suck in foreign langages)
