I ran across an issue today that my various sources of troubleshooting (ok, Google) couldn’t help solve – at least not directly. I configured SnapMirror between two disparate systems for a data migration. 16 of the 17 volumes initialized just fine, but I was getting an error on the one volume that had a LUN inside. It was a SnapDrive for Windows LUN, so I knew that just prior to the final cutover I’d have to take a Snapshot via SnapDrive, but I should be able to start the baseline transfer via the standard CLI. Here’s what I was seeing:
ControllerA> snapmirror initialize -S ControllerZ-vif01:vol_server2008 ControllerA:vol_server2008 Transfer started. Monitor progress with 'snapmirror status' or the snapmirror log. Mon May 13 14:21:26 CDT [ControllerA:replication.dst.err:error]: SnapMirror: destination transfer from ControllerZ-vif01:vol_server2008 to vol_server2008 : process was aborted.
