I hadn't thought of that but in looking at my old GC35-0154-02 IBM SCSI Tape
Drive, Medium Changer, & Library Device Drivers (installation & user's
guide) I do see where the write option of tapeutil allows you to write a
file.
# backup ~myfile.tar~ to tape
tapeutil -f/dev/rmt0 write -s myfile.tar
can then read with
# restore ~myfile.tar~ from tape
tapeutil -f/dev/rmt0 read -d myfile.tar
all sorts of useful stuff around chapter 10 (tape subcommands on pages
89-92) which is where the above examples came from.
Dang-it Steve, now I'm going to have to play around with creating a tape
validation script since I see the wtest & rtest commands... oh well, this
old dog might as well learn a new trick or two...

Subject: 3590 Partitioning
HI All,
This is a 3590 question rather than TSM as such, but this is the best
forum for it.
I need to take system images of several AIX boxes each week to SAN Attached
3590E drives in my 3494.
It seems like overkill to devote a whole 3590 tape to each image as they
will only be a few gig each.
I stumbled across some doc which implies that a 3590 tape can be partitioned
into smaller segments which can then be used independently. (see items 36
and 38 on the tapeutil menu). However, this is old doc, and I assume the
feature is from the early days of 3590 when 10GB was an enormous amount of
storage.
Has anyone used this partitioning feature? in what circumstances?
Are there any gotchas?
Thanks
