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...

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!

LEARN ABOUT SUNOS

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
