Phantom h/w errors on c0t0d0s0 on 4 V210's running solaris 8. I
couldn't tell you the patch information as that is still a possible
answer to this issue. However the customer is leasing these machines
and they seem to be doing their job quite well (webheads). Server is
using Sun Disk Suite with basic raid 1 slicing. However c0t0d0s0 is
not part of this or anyother part of the filesystem.

They increment quite slowly, but either way I would like to know the
root reason for this.

BTW, hello everyone!
