Currently in the middle of a migration from a ns704g to a ns480. Professional Services doing most of the NAS file migrations and all seems to be going OK except we are getting repeated failures of emccopy doing incremental updates. Have tried both 32 and 64 bit versions and still getting crashes on Windows 2003 and 2008 boxes.
Has anyone else run into this? Any hints? Timeline for this is to end by tomorrow so getting a little nervous.
I presume you're not using Celerra Replicator and you're copying files with EMCopy, yes? Is there a reason they chose not to use Replicator? It worked marvelously for our NS702G to NS80G migration.
Thanks for the response. Current try continues to run, but if it crashes again will try setting threads from default of 64 to, maybe, 32.
When it crashes, there doesn't appear to be specific error codes, the app (emccopy) just bombs out. The initial complete copy (Tuesday) ran thru OK, but the incrementals today are giving problems. Tomorrow AM we will be able to close open files, disconnect users, and then do final incremental.
Thanks for the help. If you have any other ideas, I will be monitoring.
Crashed again. Retrying with smaller source deff. Users are finally going home, down to about 1300 now. Restarted with threads @ 16. Probably last try tonight, will pick up again tomorrow AM.
Thanks for the help. Will post results/progress. Support Req. also opened by PS. Will get their results also.
Reducing the thread count, along with users departing, appears to be the trick. Most recent incremental worked and we are in the throws of final file system update, confirmantion, and migration. Thanks.
BTW, since this IS my last rodeo ( I am retiring end of Oct.) I want to thank all of you for allowing me to mostly lurk on the forum for the past 8 years and pick morsels of experience. Good, free flowing information helps a lot and this forum has been the best.
Glad you are able to retire. For any others reading this thread: I have found that in newer releases of EMCopy 4.0.7, it would crash if it ran into too many orphaned SIDs (AD users no longer a part of AD). Version 4.0.3 worked fine after running into this issue. Addendum: I was running 256 threads in both versions.

make sure you have latest version from Powerlink
also be careful with the nr. of parallel threads to not overburden the Windows client
