hello, I had an interesting development today. I labeled a dlt IV tape
( standalone tape drive) for a new backup using bconsole. It took
sometime to return, so I went out and started looking at logs. It
completed successfully. The message log did not have anything in it but
when I did a 'dmesg', it listed a number of errors. I have attached
them. Should I be concerned with this or is it fixed in one of the new
updates.
I am running 5.0.1 on FC 12 ( director, storage), FC13 (storage server)
and all clients ( windows, linux, solaris)
thanks,
jerry
