SAMGrid Plone

Dear Vlastislav,
The CRC data is filled by FSS when transfer is requested between 2 different
nodes. If both durable location and temporary staging area are on the same
machine, FSS does not autimatically compute CRC value. To have that valued
filled , you can either push the file further to tape or use "sam calculate crc"
command explicitly.
Regard,
Andrew

Dear experts,
I would like to ask,  how to tell the v7 sam to fill CRC value  when doing
transfer  of file in sam:
sam request file transfer
--sourceFile=`pwd`/CAF_p18.07.00_FPD_test-recoT_daq_test_1_0000215417_018.raw_p1
7.09.06_hynek_sam.farm.particle.cz_035804_1056_FZU_GRID.root
--station="d0_fzu_prague2"
--destinationPath="sam2.farm.particle.cz:/raid4_work/samgrid2/jim_tmbs"
--waitForCompletion; done
This is  the  resulting metadata, but the CRC value isn't  filled.
I would like to have  files in sam with CRC  filled, then I  suppose
that  I can  relay on  inherent mechanims in sam  that guarantee that
only copies of files with CRC matching the  metadata  values are kept  in
caches.
Could  you please commnet or clarify .
