After a fair amount of testing and investigation I determined that my missing drive is still good. The workaround for the problem is go be found in the release notes under "Hardware?Related Issues and Bugs", "SPARC: SCSI Second Disk Fails to Attach After Solaris Live Upgrade (6684776)" (http://docs.sun.com/app/docs/doc/820-4078/gdzoo?a=view).
I did not use live upgrade but it seems that the same bug is encountered. Apparently the drive must be powered down between the time it is first detected and when the kernel configures devices for it.
