Hello,
I'm trying to configure a surestore 40fx optical library on a D320
machine running hpux 11iV1. I'm wondering if there is a way to make the
optical library as a single virtual disk, but I still not found anything
on the hp documentation.
I configured the kernel drivers, so the system recognizes the library,
it also sees all the media installed, but seems that there is no way to
aggregate the capacity of the media togheter. All I succeeded to do is to
initialize and mount one disk at a time, even enabling the automounter.

Greetings

All I can speak about, is up to and including HPUX 10.20.
(But you will see some tendency...)

There once was a driver (in 9.X ?) to mount all (sides of) the MOs in a MO library to different directories
Then the driver would change the disk and/or swap the side as needed.
This was really ugly, e.g. if you happened to copy a file form a to b and a and b where on different media (or different sides of the same media), the file would be copied in chunks of a (small) buffer size, with one swap forward and one backward for each buffer size of data - annoying.
So in 10.20 this driver was dropped. I would be astonished, if it would now have come back.
I tried to find the name of the old driver in my old logs, but failed - sorry

My idea about the usage of the library was a little different, I tried to
create an lvm volume group by concatenating the media surface one after
the other. In this way the media should be filled in sequence, but the lvm
manager did not allowed me to do so

Well, there is a similar way to configure an autochanger under linux using
the automounter and mtx, but I never tried, since my 40fx misteriously
loose about 1MB of data for each write under linux (and of course, the
library drive used in an external box works just fine......)
