Howdy,
I'm not an expert on SGI's but that's what we're running here
so let drop my $0.02 of advice...
I have 2 libraries, an Adic Scalar 218 with DLT7000 and 18 slots and a
StorageTeK L40 with 4 Seagate LTOs and 40 slots. I experimented with
chg-scsi 2 years ago and had a lot of problem to drive the Adic
library until the maintainer of chg-scsi (whose name escapes me at the
moment, sorry) gave me some help and managed to make it work, or sort
of. Since then I've moved to mtx/chg-zd-mtx and I have had no problems
whatsover. I humbly suggest that you try it.

You should maybe use the 'real' devices located in the /hw
pseudofilesystem and use the norewind-noswap-variable block size
tape device, ie (in my case):
/hw/tape/tps12d1nrnsv
and the changer scsi device
/hw/scsi/sc12d5l0
and make a symlink /dev/changer to it to make mtx happy
(less typing).
but I'm being picky here..

Excess on occasion is exhilarating. It prevents moderation from
acquiring the deadening effect of a habit.
