Mounting an additional HW now no CLI

I have a SUN V245 with Solaris 10 newly installed. I have 4 73Gb HDs in this server and thought I'd use one of the other 3 to load some applications but after issueing a mount it appears that I no longer have a CLI interpreter --

# mount -F ufs /dev/dsk/c1t2d0s0 /usr
# df
bash: /usr/sbin/df: No such file or directory
# df
bash: /usr/sbin/df: No such file or directory
# pwd
/etc
# cd /
# df
bash: /usr/sbin/df: No such file or directory
# man df
bash: /usr/bin/man: No such file or directory
# umount /dev/dsk/c1t2d0s0 /usr
bash: umount: command not found

can't even reboot as cmd is not recognized ...

What did I do here?

Thanks,
Bill

Hi.

$ uname -a
SunOS vm-solaris 5.10
$ whereis umount
umount: /etc/umount /sbin/umount /usr/sbin/umount

The file in /etc and /usr both are symbolic links to /sbin, so you should be able to use:

/sbin/mount /usr

to uncover your original /usr

The reason it worked like this is:
