Will VALIDATE save transfer time?

2013-05-16 Thread Ken Leidner
I asked this earlier using the INSTALL command to perform the writing 
of the home address and was correctly pointed out that the command is 
not valid on the device.  But the person missed the true point of my 
question.


So now using VALIDATE to write the home address and clear off the 
tracks, does anybody know the answer to my question?


I am running Global mirror on an IBM  8300 DASD box.  I soon will be
TDMFing the volumes to a new 8870 box and starting a new Global
Mirror session from the new 8700 box.  I have some volumes that use
to be active (had datasets on them), but since have been returned to
a free status.

My question is would running ICKDSF with the VALIDATE option of the INIT
command on the free volumes save me transfer time?  Either with TDMF
moving the volume or Global Mirror syncing the volume.  The thought is
that maybe since INSTALL writes the home address on the volume all of
the user data is removed and the volume would compress very well and
therefore transfer very fast.   True?

If they are empty, Don't move them at all.
Vary them offline.  Rename them to something you don't move (ZZ).
Init new dasd as spares and the one you don't use at targets become
your new spares.
