I’m not sure I want to embed flash on this page just yet (I might some day do up a click-to-load javascript thingy, but I’m currently enjoying the “state of lazy”), so instead here’s a link to a video of a big ol’ tarantula, that I call Jane.

A while back we determined what was the cause of some specific errors related to the IBM TS3200 library. I forgot to post about ‘em until now, though. Here’s the error message from mtx:

backup1:~# mtx next

The problem (at least in our case) is that the tapes don’t always easily come out of the magazine. 81/8A indicate hardware failure, IIRC.

There are little pieces of plastic inside the magazine slots that are designed to hold the tape in place. They give when the tape is tugged on just slightly, but some of them are holding on too tight. In some cases, I can get it to load a tape when I try again and again, and sometimes it just requires physically removing and replacing the tape over and over to weaken the magazine’s grip. It may be that we could order replacement magazines from IBM, but I think due to the nature of this problem, there’s no guarantee it won’t recur (the magazines were fine when we first used them), and it may actually go away over time, with use.
