I think Solaris Sparc does not make a 2nd bootable partition (recovery partition) by default.
So you'll need to boot from a Solaris installation CD (usually the 1st CD in the package). Do not start the installation, but open a shell.
From there mount your disk device to /a
Then your crypted root password can be deleted or changed in /a/etc/shadow
You have to know (or guess) your disk device. Look it up before, on your alive system with
Code:
df /

If it's like /dev/dsk/c0t0d0s0 then it is a physical disk, that you can mount when booted from CD.
If it's a Solaris volume manager disk then recovery might be more complicated; try the Oracle Web documentation.
If it's zfs then I have no experience...

vipw(1B)					     SunOS/BSD Compatibility Package Commands						  vipw(1B)

NAME
vipw - edit the password file SYNOPSIS
/usr/ucb/vipw DESCRIPTION
vipw edits the password file while setting the appropriate locks, and does any necessary processing after the password file is unlocked. If the password file is already being edited, then you will be told to try again later. The vi(1) editor will be used unless the environment variable VISUAL or EDITOR indicates an alternate editor. vipw performs a number of consistency checks on the password entry for root, and will not allow a password file with a "mangled" root entry to be installed. It also checks the /etc/shells file to verify the login shell for root. FILES
/etc/ptmp /etc/shells ATTRIBUTES
