Even though I'm under 6.5.28, the LTO3 isn't really rolled into the operating system. I hammered away at the /var/sysgen/master.d/scsi file, and rebuilt the kernel several times, but the drive hangs when I try to read it back. I've tried a couple of different setups, each time getting the same result.

This appeared to write out 380GB fine, but I wasn't able to get it to read back at all:

a little closer. This one ran better, but hung after reading back about a thousand frames (12GB):

Hello,

You are loosing your time.
You must pay the APD licences for LTO.

Everything past the dlt is now used via a special daemon.

I broke down and contacted SGI about APD for this drive. Their response follows:

Hi,
I can confirm to you that there's no support for quantum LTO 3 drives.
We only support IBM and HP. W e don't forsee quantum support in the
plans at this time.
Let me know if you want me to contact our sales rep. that takes care of
the tapes drives to ask him to send you a quote on a supported TP.

I was always under the impression that Quantam made all the drives and the OEM's just rebadged/rehoused the mechanisms....???

The whole point of LTO is the idea that the hardware is "open". Anyone can manufacture it. DLT is Quantum, but LTO is produced by three different manufacturers (maybe Sony will produce these too since DTF has dead ended).

from the Quantum site:
As a result of the Certance acquisition, Quantum is the world’s largest volume supplier of both tape drives and tape automation. With the breadth of Quantum’s portfolio, we will be able to provide both channel and OEM partners with a single source of backup, recovery and archive solutions not available anywhere else.[/u]

My vendor exchanged my drive for the HP, works OK, but it's slow - see my other post at http://forums.nekochan.net/viewtopic.php?t=9663
