Hi Dennis,
You might be running into this issue:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6856341
The workaround is to force load the drivers.
Thanks,
Cindy

I find that some servers display a DEGRADED zpool status at boot. More
troubling is that this seems to be silent and no notice is given on the
console or via a snmp message or other notification process.
Let me demonstrate :

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 ?
Oh, also, I should point out that it does not matter if I boot with init S
or 3 or 6.
