snicker #2: lustatus
Solaris is Sun Microsystems' version of Unix. New commands are added all the time, but you don't notice many of them if they're not related to what you use the computers for. I'm not familiar with Sun's Live Upgrade process, so I didn't read the name of this command as Live Upgrade Status....System Administration Commands lustatus(1M)
