Thanks for the confirmation. I too am getting ready to format 20TB+ on 2-other servers so I guess I will have to update the servers to 6.2.3.0 first (or jump straight to 6.3)
I wonder if this will effect FILE devclasses/processing? I have tried to use FILE devclasses numerous times and always see performance problems and have reverted back to fixed, formatted volumes.

This update was released just in time for me when I had to format 40 TB of disk/file on a new server. Would have taken a week otherwise. I guess it does the same as on the windows platform so no need to write zeros on all blocks on unix anymore. Hans Chr.

It can't be the hardware since this is a 3+ year old machine.
