Tape drive not detecting

csreenivas — Fri, 28 May 2010 05:51:52 GMT

Hi

Our Tape drive is not detecting using ioscan on HP-UX B.11.00 A 9000/879 machine.

unknown -1 10/4/12.5.0 UNCLAIMED UNKNOWN Quantum DLT4000.

We replaced Tape drive still not detecting.
Mother board crashed recently due to power outage and we replaced new mother board .

Do I need to rebuild kernel for tape?
This is a test server and I have no previous experience in rebuilding kernel, can anyone please suggest me the commands

hi,

check if you have the "stape" driver loaded in the kernel.

hi,

if its possible to reboot the system, i would recommend to do it.

if not, you could user rmsf -H ( drive path )

ioscan -fnC tape && insf -eC tape

Hi,

kcmodule | grep -i stape

it should show stape=static

if not use

kcmodule stape=static and reboot

run ioscan -fnC tape

insf

you need to use kmmodule if your os is v1

Use SAM -> kernel drivers and add the stape driver, reboot and the tape should be CLAIMED.
