I will try to answer but I really think you should post and ask this on Galaxy Tab2 forum or other develop forum not in LG Motion forum here. I will try to help you one more time.
Also please note I don't have this device so my answer below may not be 100% correct. You may have to get confirm from Galaxy Tab2 dev...
It seems like your system, cache and data folders are defined as below.
/dev/block/platform/omap/omap_hsmmc.1/by-name/FACTORYFS
/dev/block/platform/omap/omap_hsmmc.1/by-name/DATAFS
/dev/block/platform/omap/omap_hsmmc.1/by-name/CACHE
So open up any similar Samsung device definition file with Notepad++ then replace each line accordingly. So your sys_mnt should look something like this.
sys_mnt=\/dev\/block\/platform\/omap\/omap_hsmmc.1\/by-name\/FACTORYFS
After all change is over do 'save as' then use the device name as a file name.
Again, I don't have this device and this is not a Galaxy Tab2 forum so... no guarantee

get help from Galaxy Tab2 Developers.
Good luck!
