Issue after jumpstart with Solaris 10 u7

I am performing this installation on a Sun T5220. There is an aftermarket Adaptec StorageTek raid controller card installed. I have created the raid array, and it is referred to as c1t0d0. Here is the profile I have created:

install_type
initial_install
system_type server
cluster SUNWCXall
partitioning explicit
filesys c1t0d0s0 248026 /
filesys c1t0d0s1 16386 swap
filesys c1t0d0s3 15366 /var

After this, the install proceeds without too much problem. After the install reboots the server, I receive the following messages:

I have rebooted to the OS install cd and run fsck, and there are no errors.

Here's my vfstab file:

When i try to remount using

remount -F ufs /dev/rdsk/c1t0d0s0 /

I receive an error stating:
That /dev/rdsk/c1t0d0s0 is not ufs. Except it is ufs!

I'm kind of lost. Any suggestions? This is a new system so I'm strongly considering just nuking the install and trying again.

what kind of raid adapter are you using? i need the part number. certain controller need a newer version of solaris for driver support... if an older solaris version is used, you need to patch the driver into the minikernel...

Maybe it is saying the cd is not UFS, and remount cannot switch FS types? Just a swag, for the message not the root cause!

The raid adapter is
sunFRU 375-3536-06

Model#: SGXPCIESAS-R-INT
Adaptec Internal 8-port SAS HBA

Does that help?

from the systemhandbook:

so your solaris version should be ok. my first try would be a clean install from DVD and check if everything is ok. if this works, it should be a jumpstart (wrong config...) problem.

also make sure this is true:
