Re: QIC tapes are always a mystery to me

According to page 346-347 of the V4R5 System Handbook, the 6380/6480
(2.0GB) and 6381/6481 (2.5GB) drives are not capable of reading either the
MLR1-16GB QIC 5010 format or the DC5010 QIC5010 format.  See the following

Seems to me that whenever I have a QIC tape in my hand the tape drive on
the
machine in front of me won't read _that_ particular tape...

So the other day, I was trying to make a tape for a machine that I think
has
a 2 gigabyte drive.  I tried 4 different tapes with various cryptic
manufacturer's labels on them, initializing each one with DENSITY(*CTGTYPE)

in order to discover what density the media was.  All were greater than
2GB.
  So I dug around in the media cabinet and finally found a tape that is
manufactured by IBM and it says "MLR1 2GB" and also that it is 2GB
uncompressed and 4GB compressed.  Eureka! I have it, I thought to myself.

Since the media was known to be 2GB, I did my INZTAP with DENSITY(*QIC2GB).

It initailized to *QIC5010 with a warning message something to the effect
that it had done me a favor.

I wasn't able to figure out from the help text what *QIC5010 is, and I was
frustrated and out of time, so I went ahead and saved my stuff.  I am
hoping
I will be able to restore to a 2GB QIC drive.  Does anyone know for sure?

Thanks for your help,
