xstm diagnostics said the disk was bad, so I swapped it and still having the same issues:

xstm:


Tue Aug 29 16:41:41 2006: The data read back from the device at
/dev/rdsk/c3t0d0 at block 222918 differs from the
data written to the device.

Possible Causes/Recommended Action:

The device or the medium may be faulty.


The device or the medium may be faulty.

If the device has removable medium, unload the
medium, load a different one, and try again.

What could possibly this mean? SCSI controller?

[Ivan Ferreira · Accepted solution]

Before thinking in the controller, have you verified that the SCSI bus is properly terminated and also, have you tried changing the SCSI cable?

There is no SCSI cable involved as these are internal disks.

[A. Clay Stephenson]

Whether internal or external, SCSI drives have cables --- though they might be Fibre.
Generally internal drives have cables with a built-on terminator and these have been known to fail. A poorly terminated SCSI bus will almost work perfectly --- the worst kind of problem.

[dictum9]

would you have to take apart the whole thing to check it?

[A. Clay Stephenson]

I haven't dug through your entire other thread to see what kind of equipment this applies to but generally the approach is to open up the box and replace the cable. It's usually a 10-minute operation but your mileage may vary. You could also simply have a poor/loose internal connection.
