Tape device no more recognized
I work on a HP-UX B.11.11 U 9000/800 machine.
There's a SCSI connection between the server and the tape device which is external.
We unplugged the connection and plugged it again. Now the tape device is no more visible.
And I cannot use it of course.
How can i check/reconfigure it?
Thanks a lot,
Stefano

Reboot the server with the tape connected to it.

Re: Tape device no more recognized
Is it the tape device online? What is the result of "ioscan -fnCtape"?

Re: Tape device no more recognized
Check the cable is it ok or faulty? replace the cable and check..
Check the tape drive into other server is it visible there ? if yes that means cable is ok
conncet to your system and do a "insf -e"
then check with ioscan -fnC tape
if still not visible then reboot your server.

Re: Tape device no more recognized
In spite of all I still cannot see the tape device.
Output of ioscan -fnC tape is void.
I'm going insane :)

Re: Tape device no more recognized
I don't remember the word void anywhere in ioscan. What is the result of this command:
ioscan -fnC tape

Re: Tape device no more recognized
For exactly this reason you should always power off the server and tape before touching the cable that way.
As long as no hardware is damaged, some pins can be bent. This happens often with the evil 68 pin connectors - 2 pins together in 1 hole.
This can again kill the hardware.
Hope this helps!
Regards
Torsten.
