Adding a DLT tape drive on a L2000

[Mike_811]

Hi,
I'm adding a HP DLT tape drive to my L2000 (running HPUX 11.0). My vendor provided me :
- a DLT tape drive to insert a SMART array
- a SCSI electronic board
- a SCSI cable
- a SCSI terminator.
My smart array has already a DAT tape drive.
While power OFF, I've inserted the board in an empty slot, the DLT in the SMART array and connected the cable and the terminator. Then rebooted.
Doing an ioscan -fnC tape shows me only my DAT and not the DLT.
Do I need to do anything in order the board is recognized, what are the steps ?
Thanks for your help.
Mike.

The Smart storage array can handle SE-SCSI, HVD SCSI, and LVD SCSI. It is very important that you match these components. HVD SCSI is only compatible with other HVD SCSI components. It would help if you listed the exact part numbers of your new components. Do an ioscan -fn (no -C) and post that.

Hi Mike,
You can do only
insf -e
command to make device files. If it does not work you have to check at the back of the Smart array for the SCSI address of the slot, where you put the tape. Change it to proper one and do insf -e without rebooting.

Borislav

Hi Mike,
Just check the status of the card in ioscan.

SAM-> Pheripheral Devices->Cards

Check the status of all the cards.
It should display a driver and state as active for functional cards.Post the output.

If driver is not loaded for this driver then do it. Or if that card is not visible itself then go to action and do `Diagnose a missing card`.

If card is active & still DLT is not visible then check for SCSI ID set on the tape. Try by varying it.

HTH,
Devender

Hi,
Thanks for your replies.
Hereafter the result of ioscan -fn.
Apparently the board is known as on device 0/1/0/0 .
regards.

Oops the file...

[A. Clay Stephenson]

The board at 0/1/0/0 is an HVD SCSI controller. Note that no other devices are listed on this bus indicating that the tape drive has some sort of problem. First, make certain that your DLT drive is also an HVD unit as well as the terminator. Next, you need to make certain that termination is enabled on the controller. The bus must be terminated in exactly two places -- on the physical ends of the bus and at least one device must also supply termination power. Examine the cable ends and terminator connectors very carefully for bent pins.

Hi,
According to the ioscan, the special have been created (/dev/rscsi/c6t7d0).
I've also tried insf -e
But how to link this special file to something like /dev/rmt/1** ?
Don't you think I need to execute the command mksf (something like mkfset -C tape ...)

[A. Clay Stephenson]

No, no, no. c6t7d0 is the controller; ioscan doesn't see the new tape drive on that bus. It should at least appear as UNCLAIMED. You have fundamental SCSI problems (incompatible HVD/SE/LVD SCSI components, bad termination (possibly a SE/LVD terminator on an HVD bus, or the drive is bad). When you get the device recognized, since you already have the stape driver installed, insf will create the device nodes for you.
