New Solaris 10 install, negative free space

Question

I just installed Solaris 10 from a Sun DVD over an old linux install. The install process created two UFS partitions with 0 unallocated space (I did everything the default), and everything seemed fine. The system boots correctly, and the filesystems both seem accessible.
However, in the Solaris Management Console, if I go to Storage->Disks it takes a long time to load, and then it says I have 1 disk with -1.06GB free. When I click on it, it says it doesn't see a Solaris Fdisk partition. What's wrong?
I installed it on a Thinkpad R40.

Answer 1

It looks like the filesystems themselves have free space, but the Solaris Management Console doesn't seem to think it has a Solaris Fdisk partition and wants to delete the whole disk.
I don't even know how to really look at the partition table because I'm not familiar with Solaris's device naming scheme. There's no c0d0 device to run fdisk on.
The only time I see information about the partition table at all is in the Solaris Management Console, where it tells me that there is negative free space.
