I've run lmdd many times to evaluate disk performance (under 6.5.17), but when I put together a new origin 2100 server (6.5.22), I cannot get lmdd to run without an error:

I could also use IOzone. I had used lmdd reliably for ages - Is this perhaps a symptom of another problem? I want to fix what's broken here.

I found this in the Install notes for IRIX6.5.24/complementary_apps:

Important Notes About the Products
----------------------------------
Easy Software ESP PrintPro
Easy Software ESP PrintPro package requires a license. You can
obtain a 21-day demo license for this software by going to
the ESP web site at http://www.easysw.com/license-demo.php .

ESP PrintPro replaces several files that are part of the
IRIX print product therefore these two packages are
incompatable with one another. If you install ESP PrintPRO
and later want to remove the package, you will need to reinstall
print from the Applications CD and the current IRIX 6.5 Overlay
CD in order to restore print.

Wrote on the subject of Quantum LTO3 driver for IRIX at Jan. 19, 2006, 6:46 p.m...

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:

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.

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]

I have not purchased the IRIX LTO3 Asynchronous Personality Daemon license, as this LTO 3 drive has functioned flawlessly since I traded in the Quantum drive for the HP (and edited the SCSI file).

Well, it's working fine, but it's SLOW. This takes about 36 hours to write a 400GB tape. This same tape extracts in about 6 hours.

I understand this would run substantially faster if I bought the APD package, but would I really get TEN TIMEs the performance if I had the $2500 APD license?
