Anyone help me decipher these?

At boot time, this disk was probed curiously:

Notice that only sd3 was probed with a 4.80 Mb/sec sync rate, even though I
have two other disks which are the same exact physically identical drive.

I'm curious as to whether these messages point to the disk itself (sd3) or to
the communication on the SCSI bus (i.e., maybe a cable needs to be replaced or
shortened, etc.).  Since they're not the same exact format as the SunOS 4.1.x
esp messages I'm used to deciphering, it's not obvious to me.  Thanks.
