Will running INSTALL help?

2013-05-15 Thread Ken Leidner
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 INSTALL 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?

ICKDSF INSTALL is not supported on IBM 2105/2107/1750
