I believe that you can get to single user mode with a full root filesystem. If not, then yes, you will need to boot the cd.
But first you need an ok prompt. The procedure to get one varies according to your hardware. With a serial console it is just the break character. I have heard that Solaris 8 has changed this to:
C/R control-b ~
And you need .5 seconds between each char but not more than 5 seconds in total it says here. I'm not sure how much of this I believe...
With a graphic head the sequence is STOP-A.
There may be key which need to be in a certain position.
And it may be some other sequence for your setup. But these are the ones I know.

sulogin
sulogin(1M) System Administration Commands sulogin(1M)
NAME
sulogin - access single-user mode
SYNOPSIS
sulogin
DESCRIPTION
The sulogin utility is automatically invoked by init when the system is first started. It prompts the user to type the root password to
enter system maintenance mode (single-user mode) or to type EOF (typically <CTRL-D>) for normal startup (multi-user mode). The user should
never directly invoke sulogin.
The sulogin utility can prompt the user to enter the root password on a variable number of serial console devices, in addition to the tra-
ditional console device. See consadm(1M) and msglog(7D) for a description of how to configure a serial device to display the single-user
login prompt.
FILES
/etc/default/sulogin Default value can be set for the following flag:
PASSREQ Determines if login requires a password. Default is PASSREQ=YES.
/etc/default/login Default value can be set for the following flag:
SLEEPTIME If present, sets the number of seconds to wait before login failure is printed to the screen and
another login attempt is allowed. Default is 4 seconds. Minimum is 0 seconds. Maximum is 5 seconds.
Both su(1M) and login(1) are affected by the value of SLEEPTIME.
