Solaris 10 failsafe can not mount root

i have a major problem, i renamed the ld.so.1 file.
so i want to reboot into single user mode / fail safe / cdrom single user but i will not mount the root disk.

if i look in /dev/dsk all i see is ide disks (cdrom) and no actual disks.

If you booted from cd into single user mode, you have to manually mount the root disk so you can see it.

mount /dev/dsk/cxtxdxs0 /a
cd /a
ls

You will see the contents of /root
