Help with unbootable T2000

Hi,
I have a T2000 that I was adding a kernel patch to, that had the power
interrupted for various reasons. We are still investigating this.

This caused the system to fail to boot.

I then tried to replace the kernel via netboot mount and decided
to restore some components of the OS from tape, because I couldn't
back out the kernel patch. This worked until the system decided to
panic and it seems to have completely corrupted the boot disk.

Anyway, I am now left with a system that is in an unusable state.

Given I have a netboot environment available, can someone please
outline a procedure to get this system going again without a reinstall,
which would probably ruin the total environment on there?

I have ZFS filesystems mounted on a SAN via mpxio so I do not want
to go through having to rebuild all that as well.

Is there something I can do, like restore the OS from tape and then
dump it back onto the boot disk, do an installboot and so on,
to get the system up again?

I am hoping I just have to copy back / (includes /usr) and /var to
get going again.... true or not?!

Please help = I have 2 days!
