I have many systems where I keep mirrors on multiple controllers, either
fibre or SCSI. It seems that the SCSI devices don't get detected at boot
on the Sparc systems. The x86/AMD64 systems do not seem to have this
problem but I may be wrong.

Is this a known bug or am I seeing something due to a missing line in
/etc/system ?

My Sun Blade 2500 (Red) does see both boot disks. However, I do recall an issue at one time with the Solaris power management daemon in that it shut down the second disk during boot so that it was not seen. It was mentioned in the Solaris release notes (maybe U5 or U6?) and it happened to me. A fix to /etc/power.conf was required. Perhaps that is what is happening to you.
