After HP_LTT35 installation

[Hakki Aydin Ucar]

My DAT is HP C5683A, after upgrading ignite some of the servers in cluster cannot see tape. Driver stape is there, only found that LTT was not there. And installed HP_LTT35 .
ioscan -fnCtape still cannot show DAT
insf -e is not good to retrieve DAT (of course drivers already available)
is there anything after LTT installation to make tape visible to server ? OR just need to reboot ??

Hi

Is the ioscan -fun show any device in 'NO_HW'?

Please restart the system and try ...

Yes I checked already, No NO_HW device there.
Thanks.

I beleive, you need to reboot the system. Is it possible?

Hi,

You didn't mention in this Forum that you're using a Dat USB interface, but just in case, be aware that HP-UX does not support USB hard drives or USB tape devices.


Thank you,

This drive is SCSI, isn't it?

What server model and where is it connected?
Terminators in place?

[Hakki Aydin Ucar]

Storage works DAT40 and connected to Tape Array 5300, Yes it is scsi not USB .

If you don't see the drive in ioscan, you cannot do anything with LTT.

Did you move the drive around before?

Again, what server? Where connected?

Pull and push the drive again. Check the cable for bent pins.

sorry I forgot to say server; it is rp7410 nPartition (double partition), HP-UX 11i v1

Yes, I tried but LTT cannot see lost HW, today I ll try to take out DAT and put back it again

Hi again,

My problem has been solved by pull and push DAT driver without reboot server. I was lucky.
And LTT sees Tape HW now.

Actually I still wonder and not quite sure what is LTT good for ?

[Torsten.]

LTT is used for toubleshooting, testing and updating all HP tape, optical and library devices.

Consider to use a newer version ;-)
