Its a UNIX platform, so I thought some knowledge might be shared.

I have a Solaris station that was powered off physically instead of being shutdown. The vfstab file is now comprised of a couple lines that have nothing to do with mounts. So as a result when it boots it errors out saying the lines are invalid. I ran fsck on the actual disc (/dev/rdsk/c0t0d0s0) and it passed. I have a backup of the vfstab file, but when I boot to single user mode the hard drive is locked and I can't copy the backup to the actual.

I tried mount /dev/dsk/c0t0d0s0 from the command line in single user mode and it errors out saying the vfstab file is invalid.

Any ideas how to make the hard drive writeable so I can restore the vfstab file?

Boot into single user from cd (boot cdrom -s from the ok> prompt). I usually used the first of two software cd's to boot from. Once in single user you should be able to mount the /dev/dsk/c0t0d0s0 partition on /mnt and modify it from there. As a precaution, unmount /mnt prior to rebooting so that it's gracefully sync'd and unmounted.
