I haven't had a chance to check any of this because the machines in question
are off-site. I will be checking them later. The problem seems to have
gone away for now. I was getting this error on 3 new machines.
Here are the responses (Thanks for the help):

 Bug Id: 1172254
 Category: kernel
 Subcategory: driver
 Release summary: 4.2
 Synopsis: 'polled command timeout' error; can't determine device state
        Integrated in releases:
 Patch id:
A 'polled command timeout' on a disk drive during a system boot needs additional
information displayed so that the Vendor, Product and Revision Level of the devicecan be determined from the log data.
(This is the info from SunSolve.)

From: "M.Masarati Cadds/Unix Support +39 2 26913370)" <'ve just seen this message and the problem was the ethernet cable :
the yellow cable of the network has 2 terminators at the begin and at the
end of the cable,If you got a tester try to test the electric resistance
of the terminators, it must be 50 ohm.
Also try on the tranceiver, the resistance must be 25 ohm .
I've got this problem because my tranceiver resistance wasn't 25 ohm,so it
caused network problems on the net with this console message.

Install 101378-09. This should fix the problem (at least it did for us).

From: "Srinivasa R. Yalavarthy" <>
this is definitely due to bad scsi. You need to check your scsi cable first, then check
for scsi terminator. You should have one if you have a daisy chain on your scsi. It seems like
target 6 is the culprit, which is usually cdrom. So I would check all those things then if the
problem still persists, I would check scsi fuse on the mother board.

From: (Bismark Espinoza)
You may have SCSI-2 and "fast SCSI-2" devices in some
of your SCSI chains. There may be communication
problems from scsi controller to/from device.
A previous letter referred to patch #101378-09 that
supposedly fixes it. Another fix is to have chains
with only one type of peripheral.

From: (Richard Ravich)
It appears to me that what is causing the problem should be reported before the
error messages that you sent out. I'd suggest that there may be a problem with
the SCSI code on the drive (I hope it is not one of ours!) or a possible problem
in termination or cabling.
For what it's worth, the command that is giving the problem is a request sense
command, and as far as I can tell, should work.

Perhaps they are FAST-SCSI-related errors.
