install problems freebsd on Sun Netra T1

[Johan]

Hi

I've been trying to install FreeBSD 6.2 on my Netra T1.

I've this problem with sysinstall.

When I'm in the partionner, I can't save properly the partitions I
just created.
The system tells me it can't mount the mount points.

What's missing  ?

Do I need to use sunlabel to partition properly the disks ?

Where could I find a documentation explaining this ?

Thanks in advance

Johan
