Hi,

I have problems with Exabyte Magnum 1x7 LTO autoloader with one IBM LTO2
tape drive on an E420R running Solaris 8. It is connected to a LVD SCSI
card (option X6758A), sgen driver is configured and I have even installed
some software (libTool and ltoTool) for Solaris from Exabyte to control the
loader and the tape drive (their equivalent of mtx and mt commands). After
rebooting, there are entries in /dev/scsi/changer:

bash-2.03# ls -l /dev/scsi/changer/
total 2
lrwxrwxrwx 1 root root 58 May 31 13:01 c4t0d0 -> ../../../devices/pci@1f,4000/pci@4/scsi@4/sgen@0,0:changer

and both mtx and libTool have no problems reading status:

bash-2.03# /usr/local/sbin/mtx -f /dev/scsi/changer/c4t0d0 status
Storage Changer /dev/scsi/changer/c4t0d0:1 Drives, 7 Slots ( 0 Import/Export )

All drives are reported empty


however, if I try to move a tape from e.g. slot 1 to the tape drive, I get
the following error(s):

bash-2.03# /usr/local/sbin/mtx -f /dev/scsi/changer/c4t0d0 load 1

and

libTool V1.62 - (c) 2002-2004 Exabyte Corp.

Sense=04H [Hardware error], ASC/ASCQ=15H/83H
Library failed to place cartridge

I have even changed the emulation to something older (EXB 210 mode), but no change.

Does anyone have a clue what is going on here? Is this a "too new HW for my
software problem" or is this a HW problem? The tape is in a remote location
(few hundreds kilometers away) and I can't go there to manipulate it
directly.

Thanks in advance and bye, Dragan

Never mind. Got a solution from Exabyte customer support:

During shipment of the Magnum 1x7 2U, there may be enough shock and
vibration to cause the Load Lock on the LTO drive to move into the
set position. If the Magnum 1x7 2U library is at firmware level
V1B004, it may fail to load a cartridge into the drive. This will
show up as a failure to move tape into the drive on the first tape
load.

Updating the library firmware to V1B006 will fix this problem.
With V1B006 firwmware, the library picker will load a tape into the
LTO drive even if its Load Lock is in the set position. After the
first successful tape load and unload, the LTO Load Lock will be in
the correct (open) position.


Updated the firmware and the drive suddenly started working. Funny.

Bye, Dragan
