DLT not detected by the system

[meekrob]

Hi all ,
i have a L3000 server that is connected to an External DLT40/80 Tape drive ,

the drive is seen from the PDC level (at the hardware level ) , but from the OS when i type ioscan -fnC tape , it did not found it ,

what should be done ,

Thank you

Is the driver 'stape' in your kernel.
If not, add it to your kernel and reboot the server.

Hi,

if you can see in ioscan "UNCLAIMED" and UNKNOWN, this is a problem of the missing "stape" driver.

[Enrico P.]

Hi,
check if you have the "schgr" driver loaded also (Tape Autochanger Hardware Driver) to move the Autochanger.

i have changed the stape and the schgr driver from unused to static but still not work , the ioscan -fnC tape did not give any output ,
note that the version of HP-UX is 11.23

Thank you

Hi,
can you post the output of the "ioscan -fn" and "kcsystem" command? Also try to follow the step in http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=lpg50207&jumpid=reg_R1002_USEN

If your tapeunit is a HVD/FWD SCSI unit it will not work.
Since HP-UX 11.23 HVD/FWD SCSI interfaces and devices are no longer supported.

[meekrob]

yes it is a differential SCSI tape drive ,

is there a document that proove that it did not work with HP-UX V2 ,?

No FWD SCSI adapter or device is supported on HP-UX 11i v2 or 3 - see the quickspecs for 11i v2/3.

You need LVD or SAS SCSI devices.

[meekrob]

it is a Smart DLT8000 C6379A ,

[Torsten. · Accepted solution]

Your drive is a F/W differential (HVD) SCSI device and will not work with 11.23 or 11.31.
