Migration issue

you could also try ndmpcopy as an alternative

Hi Harold!

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.

Can you post their EMC copy incremental errors?

Thanks!

Rainer beat me to it - take a look at the document in the forums on using NDMPcopyHow to use the ndmpcopy tool to copy file systems or directory structures.  Lots of good steps on using ndmpcopy!

try with 16 - even 32 can be too much in some cases

Rainer,

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.

last resort ..robocopy (with /FFT parameter) , not as fast but might work.

Rainier, et al,

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.

Thanks again

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.

There is a more recent (4.09) version available

Just wanted to make two comments here.  As pointed out, the latest version is 4.09 (released November 18, 2010).  It is available in Powerlink as follows:

Home > Support > Product and Diagnostic Tools > Celerra Tools > Windows Migration Tools > EMCOPY

Also, mentioned originally was the use of both 32-bit and 64-bit on Windows 2003 and Windows 2008.  As noted in the link above when you go to download the utility:

"EMCOPY64 is the 64bits version of emcopy. It only can be run on a VISTA or SEVEN (Windows 7) X64 system"

Therefore, you should be using the 32-bit version.
