IBM AS400 questions

Made some progress with the AS400. Looks like one of the hard drives has
failed, it stated that if another disk fails then there could be a loss of

Plan was to back up the system to a couple of 8GB QIC tapes, however
looking at my tapes they turned out to be only QIC525 MB tapes, and are not
enough to back up the entire machine.  Shopping around, i am not seeing 8GB
tapes for less than $40, which is kinda costly. I do not know how to
determine the total size of files on the system, or how many tapes the
completed backup will be. There is a scsi port on the back of the machine.
If i pick up an ibm branded drive, can i connect just any ibm branded tape
drive, or do i need a specific model? I recall seeing a 8MM drive at the
place where i got it , and possibly an external dat drive as well. I have
plenty of dat tapes, I am trying to get a drive where the media has a
higher capacity / lower cost.

I read that there is a printer port on the back of my Infowindow II
terminal, do i need a special ibm printer? if not, i have a good dot matrix
printer here with a box of paper that should do the job.

Leaving it powered down after tonight until i can make a complete save.
Thanks to all for the advice so far. Really steep learning curve but quite
an interesting machine.
