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.

Depending on the nature of your system, consider 'soft' solutions. If your data is in great big lumps then a vol copy is probably your fastest solution.
If it is broken down in many directories, consider this approach.
Mount the old space and the new space on a machine. Here's your downtime. Create symlinked directories in the new space pointing to the old space. Change your 'active' mount points to be the new space. This can be accomplished quickly relative to copying the entire data set.
You're back up now.
New data files could be written to the new directories, old data files accessed as 'in' the new directories.
A script or cronjob or something gradually performs the copy in small available downtimes, deleting the symlink and copying the data across to the new location.
Now I don't know what will work for you, you know your data and how it's accessed. But that worked for us moving users' mailboxes, because of the nature of the data. If downtime isn't an issue, then go for the vol copy. But then again, if downtime isn't an issue for you, I want to work where you work!
