[SunHELP] Solaris 2.6 booting off of mirror

Hi gurus,

I've done some studying on this and can't find the answer, but I'm sure
someone else on this list has done this before.

I'm working on a new server where I've mirrored the boot disk and installed
the boot block on the mirrored disk, but I don't know how to tell the eeprom
to use the second disk as the boot device if the first drive fails.

Does anyone know the command to do this?

TIA

Matthew
