We just installed an Exabyte 8mm tape unit on a 3/280 running SunOS 4.0.3, and are intermittently running into the following problems when reading & writing to/from the unit. Has anyone seen these problems (and/or found a solution)? The unit is pretty much unusable right now, as using it causes system reboots... Thanks in advance.
