So what it says is that when accessing /dev/rmt/0hbn it had a series of
errors 21 times in a row, doesn't have to be 21 of the same error - just
21 bad things happening.. Sometimes it's a bad tape or a WP tape,
sometimes it's a bad drive, and sometimes its bad transport...

In this case judging by the iostat output you *may* have a transport
problem - both drives are spitting out transport errors and drive 3 has
had some hard ones. If it's scsi, then I'd have a good hard look at the
cables and terminators..  A crooked plug or a bent pin are often the
cause here, but it could be a bad controller on any one of the devices
on the same scsi bus that's messing it up for all the devices.

I suggest posting the output of the inquire command to the list - that
will tell us which devices are sharing the bus with drive 0.
