Yes we dont recommend running SC from within SC for --action snap, lun_clon, vol_clone
The reason is SC sets all parameters in config to ENV and what happens is that gets inherited by PRE_NTAP_CMD which is SC running as action snap so you can get into looping issues.
If you are going to do this then use SC 3.6 since we fixed some issues with looping and in second config one run form within SC set all pre or post commands set in master config but not in child config to "echo test". This will then write over them so that the wrong commands arent run and just a harmless echo runs.
This is a bit complex though so again our recommendation is not to do this and run configs separate or create a wrapper script to chain things.
