Sorry, I forgot to mention my goal here is to do this within a script that requires as little user intervention as possible--so I'm looking more for something that would work like: shutdown -i6 -- cdrom
This is probably the method I will use if no one has the command I'm hoping is out there...

1. #eeprom bootdevice=<Physical_path_of_CDROM> (System's boot device is now CDROM)
2. #shutdown -y -g0 -i6 (Reboot. System will boot with CDROM)
3. You should again switch back to your default boot device (/dev/dsk/c0t0d0s0).
#mkdir /tmp/root/a ; mount /dev/dsk/c0t0d0s0 (Mount your actual device on a temporary boot disk)
#ls -l /tmp/root/a/cev/dsk/c0t0d0s0 (This will give you the physical address)
#eeprom bootdevice=<physical_path_of_c0t0d0s0>
#shutdown -y -g0 -i6
I tried this one as I was hoping that the CDROM program (which installs software onto a blank hard drive) would set the boot device back to a hard drive. Instead it gets so confused with seeing the boot device being changed to CDROM that the installer program just errors out and won't run. I then have to switch the boot device back to disk from OBP.
Thanks for your response though!

reboot
reboot(3C) Standard C Library Functions reboot(3C)
NAME
reboot - reboot system or halt processor
SYNOPSIS
#include <sys/reboot.h>
int reboot(int howto, char *bootargs);
DESCRIPTION
The reboot() function reboots the system. The howto argument specifies the behavior of the system while rebooting and is a mask con-
structed by a bitwise-inclusive-OR of flags from the following list:
RB_AUTOBOOT The machine is rebooted from the root filesystem on the default boot device. This is the default behavior. See boot(1M) and
kernel(1M).
RB_HALT The processor is simply halted; no reboot takes place. This option should be used with caution.
RB_ASKNAME Interpreted by the bootstrap program and kernel, causing the user to be asked for pathnames during the bootstrap.
RB_DUMP The system is forced to panic immediately without any further processing and a crash dump is written to the dump device (see
dumpadm(1M)) before rebooting.
Any other howto argument causes the kernel file to boot.
The interpretation of the bootargs argument is platform-dependent.
RETURN VALUES
Upon successful completion, reboot() never returns. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The reboot() function will fail if:
EPERM The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process.
