Oops.

Any ideas? I think someone once mentioned the M2LVD did not like Sun
gear? I stuffed it in a Winblow box and it ran fine.

First off -- do you have it hooked to a real LVD SCSI card?
Unlike most other LVD devices, it does not work properly on a SE SCSI,
and the Exabyte documentation PDFs document this. The same applies if
you have a mix of LVD and SE devices on a LVD card -- because that will
default to SE operation. I discovered all of this the hard way. :-) The
library would happily talk to the computer via SE SCSI, but not the tape
drives. They would work just enough to get status information from the
tape drives, and (sometimes) to read an already written tape. But once
I tried to write a tape -- error time. :-)

Second -- you probably need to add some entries to
/kernel/drv/st.conf

In particular, you need these in there to properly use the M2
drive:


======================================================================
tape-config-list=
"EXABYTE Mammoth2", "Mammoth2 8mm Helical Scan", "M2";

M2 = 1,0x35,0,0x19e39,1,0x28,0;
======================================================================

The above is from my Sun Fire 280R with an EXB-430 library with
two M2 drives and (currently) ten slots -- until I find more magazines
to fit the EXB-430 or EXB-215.

Note also that if you put a standard Mammoth (e.g. 8900) tape
into the drive, it *will* read it (but apparently not write it), and
will then walk around shouting "unclean" until you feed it a cleaning
tape. :-)

Scsi set to ID4 No conflicts, only device on the card.

O.K. But is it a LVD card?

Also -- are the proper drivers there for the card? Sun only
seems to supply (according to my increasingly old FEH) SE and HVD PCI
cards. All others are third-party cards, and my need a third-party
driver installed.

I did stuff a third-party LVD PCI card into an Ultra-10 and have
no problems accessing the drive -- but the OS in that was OpenBSD, not
Solaris 10 at the time.

Good Luck,
DoN.
