Hello,  Resync-prep takes time depending upon data in the policy.  Also you can check /var/log/isi_migrate.log  to check when resync-prep complete successfully. if its stuck and you do not see any progress I would recommend to open a support ticket to look into it.  Thanks Hemant
Hi,  I'm performing a DR test with SyncIQ and I would like to estimate how long the failback is going to take.  To my understanding, when doing the resync-prep (to create the mirror policy) on the source, the synciq path on the source for that policy has to be  "domain marked" in order to set that path to RO. This is what makes the failback a long process if there are many files.  Can someone confirm this is the way it works? if so ... any idea how long a failback could take?  Thanks!
