One thing to remember is to use different volume id's on each and every
tape. Those of us who came from the S/36 often got into the habit of
naming them all the same, like IBMIRD or some thing we used to label the
diskettes. However if you label them differently, and use PRTERRLOG on a
daily basis then you can see if it's one or two particular tapes that need
replacing. I reset the statistics daily with VOLSTAT and only look for
those with errors. Someone off list once set me a link to acceptable
error rates. I also used these, after some serious purging of Domino
data, to realize that we no longer needed to load two tape volumes, in
fact, it was so low on the first tape that the risk of going to the second
was nonexistent.
This VOLSTAT report gets emailed to me every morning. A message filter
stores it in it's own directory.

Tape drives for older i's






So, I'm currently using a DDS tape drive installed in my
9406-600 machine for backups.
It does OK, but I get errors all the time that the system thinks it's
failing, and it does tend to retry a lot, and needs cleanings fairly
often. This is my own personal test/learning machine, but I'd still like
to have a good backup device, but one that doesn't have rediculously
expensive cartridges like the DC9250 that I replaced with the DDS (because

I couldn't afford to have more than a few backup tapes)

What devices can I hook up to an older machine like that for backup? I'd
like something in the 20-40gb range with cheap carts and good reliability,

and it has to plug into the AS/400 without additional software. Any
suggestions?
