This is very interesting to me, as I am about to do almost exactly the same thing. We have (don't laugh, please) a single 700GB volume which I want to split in to smaller volumes. To do this we have purchased a new 760 with 8 shelves ( we need more capacity anyway). What I plan to do is use rdist or rsync to copy the data from the old volume to the new volumes. Once the initial (level 0 ) copy is done I will keep up with daily incrementals until such a time as we can arrange a short down time to do a final copy and then re-rack the shelves to split them across the two heads.
Hey presto.
I've decided not to use ndmpcopy as a colleague of mine had an absolute nightmare with it when he moved from SCSI to FC-AL.

I had a 550 GB volume on my 740 Filer and need to split into two during my plan to migrate the stuff on a new 760 Filer. Can somebody suggest a nice way out...? prem

Does anyone have a recommendation for a console connection server? We have 14 filers and growing and I'm looking for some centralized, easy serial connection box. I have used Annex in the past for UNIX, but thought maybe some folks out there in toasterland might have some ideas to share.
Livingston^H^H^H^H^H^H^H^H^Hucent Portmasters (2e) also work well and might be a little cheaper than an Annex.
On the pricy side, we have a Cisco 2511, and it does a very nice job.

Can you go into this in more detail, since this is exactly what I'll be doing when I migrate from an F520 to an F740 sometime in september/october timeframe.
From the looks of things, nmdpcopy should do a great job, but the more details of people's problems that I get, the happier I am.
Thanks, John x27548
