mount & umount in sigle-user mode
In Solaris 8, when I boot to single user mode, mount a device and then reboot or init 0, the system unmount it automatically. However, in Solaris 10 it does not seem to do the same. Here is what I did:

Code:
{0} ok boot -s
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
       0. c1t0d0 <SUN146G cyl 14087 alt 2 hd 24 sec 848>

       1. c1t1d0 <SUN146G cyl 14087 alt 2 hd 24 sec 848>
          /pci@0/pci@0/pci@2/scsi@0/sd@1,0

{0} ok

I am stuck in the ok prompt and cannot boot anymore, not even to single user mode. You can notice from above that the system "Creating boot_archive for /mnt" instead of un-mounting it. Can anybody help fixing this problem?

What was the point of mounting the root slice on 2 different directories?

Anyway, at the ok prompt, try
Code:
{}ok  boot -F failsafe

During bootup, do you get any errors "kernel struct change" or something like that?

Of course, you have to issue boot again at the ok> prompt
