Hi,

check if the DDS Drive connected (Externally , seesm so !!!) has been powered on, SCSI cables connested Firmly on the DDS Drive end as well as the SERVER SCSI Controlle end, Tape media loaded.

Also check that you have set properly the SCSI ID of the Drive (for External Drive if possible), and a terminator in place, and connecting to the Right SCSI port on the server.

What is the O/P of the command
#model
#uname -a
as run on your server.


if this is an external drive make sure that it is connected or being detatched from the server when the DDS Drive is powered off ONLY.

As when you connect the SCSI cable end to the server SCSI port with the DDS Drive powered on that can cause the reset of the SCSI buson the server.

if that is detected on the server OK in ioscan say as dev file /dev/rmt/1mn
then you can use the following commands to rewind and see the status of the loaded media after loading a media.

#mt -t /dev/rmt/1mn rewind
#mt -t /dev/rmt/1mn status

It means that there is no tape drive attached. No need to go any further. If there really is a tape drive attached, then it is defective and will need to be replaced. ioscan only finds devices that can communicate.

hi,

ioscan -fnC tape will only show tape drives with driver installed and bound to the hardware.

do a full system ioscan
#ioscan

is he tape drive unclaimed?

Also you need to check that you do not have a scsi id conflict, if on the same bus as the disks?

if its seen as unclaimed then install the tape2 and stape drivers in sam
