ioscan -funC tape

f. halili — Thu, 29 Jun 2000 19:08:39 GMT

i got a tape drive replaced and via ioscan i have:

tape 5 10/8.8.0.0.3.6.0 stape CLAIMED DEVICE QUANTUM DLT7000

after the tape drive was replaced there's a line in ioscan ( which should not be there ) :

tape 10 10/8.8.0.0.3.0.0 stape NO_HW DEVICE QUANTUM DLT7000

How do you remove this line from being shown???

Have you tried removing it(the tape device) through SAM?

Has the system been power cycled since the DLT drive has been changed? Or was it done online?

Try to delet the device file files by:
rmsf -H

and reinstall them by:

insf -H -e

good luck

Hi

Find out device driver not loaded in to kernel or not.If not add driver on to kernal ( because status is not showing as CLAIMED)

And i feel there is scsi ID clash between DLT Drive and other devices. because old drive was having ID 10/8.8.0.0.3.6.0, new is having 10/8.8.0.0.3.0.0

change new ID to 3.6.0 then reboot and try.

Now checkup #iscan -fnC tape (it should work)

suren.

NO_HW means the system was unable to communicate w/ the device or the device stopped responding. It seems like you replaced the DLT while the box was up and running. I would reboot the system then verify that it is seen properly with an ioscan and you are able to dd or tar to a tape.

Did you replace the drive online. since the old and new drives may have different
scsi addresess. reboot the server will solve this problem. NO_HW means
that the drive is not switched ON.
hope this will helps you.

It will work fine if you relink the kernel.

The second line of your ioscan output SHOULD be there since this tape device is a DLT with autocharger. The device that is not claimed is actually the robotic arm that will change tapes automatically (i.e. with Omniback). You must associate this device with the spt driver in 11.0, or the s_tape driver in 10.20. Both drivers are the scsi pass-thru driver.

Hope this helps.
