Add tape device

[juno2]

We are running HP UX 10.2 , I have a tape device /dev/rmt/0m , I tried to connect it by SAM , Action --> Add , then it scan the system's hardware , but nothing was found , could suggest how to add it in my system ? Thx.

Hi Juno,
does anything show up when you type at the command prompt:

ioscan -funC tape

- If not, this is probably overkill, but I would physically power down the HP box; resocket the tape drive cable on both ends; make sure the tape drive is plugged in and turned on; and then restart the box and retry the ioscan.

- If you do see a tape drive listed, but no /dev/rmt address mapped to it, you can fix this with the command: insf -e

- Once you see a drive listed with a /dev/rmt address, you could mkdir /tapedrive and
mount -r /dev/rmt/1m /tapedrive.

Hope that helps,
Natasha

Note: I never did that much 10.20 admin, but this is pretty general stuff.

Thx Litt and Steven ,

For Steven's method , is there any other method that are no need to reboot the system ? thx.

If the system has not identified the tape drive because the drivers are missing in the kernel, a reboot is required to add the driver in the kernel and make it active.

[juno2]

The tape device was working properly previosly, it became not work after we have re-plug the cable , do i need to follow steven's method to rebuild kernel ? thx.

[juno2]

The device can't detect by ioscan now , do i need to re-build the kernel ? Thx.

If it was working properly before, and you changed the cable, rebuilding the kernel and rebooting is going to have absolutely no effect. You need to re-check your cabling, termination, etc.

I sure the cable is work properly , it is a external device , how can I detect it and connect it ? thx.

[Pete Randall]

Try a different cable then. If the only thing you did was replug the cable, then that's the only thing that's changed!

You may have bent a pin in the connector. Examine it closely, try a different cable, make sure any terminators are properly connected.

If its an external tape drive.
1.Check both the ends of the cable to see no pins are bent (coz you unpluged and plugged back which might have ...)

2. Check that you haven't changed the ID of the tape drive.

and ofcourse the tape drive must be ON before you do ioscan
