I'm using an AHA1542 Adaptec SCSII controler with an Archive Anaconda
streamer tape attached. I tried to copy some data onto the tape (with
tar) and it worked fine. I could load it down again, append and
everyhting one expects from a tape. :)
The actuall problem I have is, when I put a bigger session on the tape
then mt (or the driver?) seems to hang after a while. I recorded about
300MB on the tape and it hung.
I can't kill mt and the tape is inaccessible (drive busy). After
rebooting the machine I tried to download all the data from the tape and
it worked again, but again it hung.
Before I started putting large sessions on the tape I tried it with
several smaller sessions (about 40MB each) and I had no problem at all.
Is there a limit to the maxmimum size of a single session? I also loaded
a tape with about 200MB on a tape with 150MB capacity to check if there
is a problem when the tape runs over, but this also worked. It seems as
if there is either a timeout due to the length of the session, or an
overflow. The only way to get the tape back working is to reboot the
Another question I have is: When the driver hangs is it possible to
reset the driver? I tried to install the driver as a module and unload
it after it hung, but this didn't work (as I expected).
