Configuring a new disk as bootable - Solaris 2.51

My goal is to attach a new hard drive to the system and make it bootable.
Then I want to configure the system to boot between the existing system
bootable harddrive and the newly reconfigured hard drive. I think the
following procedures are a start; let me know if I omitted something.
 

    Procedures for making the new disk bootable:

    1) format harddrive
    2) newfs
    3) Should I use Installboot and copy over the boot block?

    Configure system for dual boot:

    1) setenv boot-device disk<disk#>
    2) setenv auto-boot? false
    3) reset
    4) boot <current boot disk> or <new boot disk>
    5) Did I leave anything out??
