NO_HW in ioscan output

[???_185]

Hi,
I've just attached a ultrium460 on my k360 server but the ioscan -kfnC tape state="HO_HW".
(k4360 -> 28655A -> ultrium460 -> SE Terminator)
=======
ext_bus 5 10/4/4 scsi1 CLAIMED INTERFACE HP 28655A
target 12 10/4/4.3 target NO_HW DEVICE
tape 2 10/4/4.3.0 tape2 NO_HW UNKNOWN HP Ultrium 2-SCSI
=======
What can I do to get CLAIMED instead of NO_HW ?

Regards,

No hardware specifies you were having a orking hardware, but hardware has been physically unplugged/removed...

Have you tried the followinf steps :
. Ensure everything is well plugged
. "insf -e" command to create missing devices

Regards,

Fred

yes,
try insf -e ( install all the special files)
or insf -H (hw path)

sorry, cable has been unplugged.
But the ioscan -fknC tape state ="UNCLAIMED".

target 11 10/4/4.5 target CLAIMED DEVICE
tape 1 10/4/4.5.0 tape2 UNCLAIMED UKNOWN HP Ultrium 2-SCSI

still getting error

hi,

try without "-k" :)

This tape drive is way faster than that system can ever push data to.

I would suspect you don't have the device hooked up to the right kind of scsi card. This device requires an LVD scsi card LVD. Take a look at the stamp on the scsi card. If it does not say lvd, disconnect the device immediately before you damage it.

ioscan -fnC ext_bus

This will show you what kind of scsi cards you have in your box.

Also, don't forget to put the stape driver to status in in kernel drivers.

try,
ioscan -fnCtape ( if is still NO_HW)

insf -e

ioscan -fnCtape

I agree with SEP. the K-class's 28655A card only pushes data at 5 MB/ second, and the Ultrium 460 needs 30 MB/ second minimum to keep the pipe full. If you attempt to use the Ultrium 460 you will be extremely disappointed with the performance. Also, the tape will constantly be rewinding and seeking which will shorten the life of the tape drive by a huge amount.

What you should be using with a K360 is a DLT 8000 that connects to the Fast-Wide 28696A or A2969A card. These are the fastest drives designed to work with the K-class servers.

i got same result after ioscan -fnC tape, insf -e, ioscan -fknCtape and put the stape driver in kernel drivers

ext_bus 5 10/4/4 scsi1 CLAIMED INTERFACE HP 28655A - SE SCSI ID=6
target 11 10/4/4.5 target CLAIMED DEVICE
tape 1 10/4/4.5.0 tape2 UNCLAIMED UNKNOWN HP Ultrium 2-SCSI

go into SAM:

peripheral devices
tape drives
select actions menu
diagnose missing tape drive

It will ask if you want to rescan. select 'no'
It will ask if it is connected, etc. select 'yes'
It will ask if it is being used. select 'no'
It will then offer to install all the tape drivers into the kernel. On my workstation with 11i, (no tapes installed) it says:
schgr
scsi1
spt
spt0
stape
tape2
target

It will ask if you want to add these drivers to the kernel. select 'yes' -- WARNING!! THIS REQUIRES A REBOOT!

it will then confirm that you want to reboot, etc.

once it comes back up, it should recognize the tape drive.

PS - once again, please do not use this drive with this system. it will destroy the tape drive after a very short time!!!

thats a good point to make cheryl!

but also what version hpux are you running?
and is the system upto date with patches as there were patches released for support of the the newer tape drives also, including updated stape drivers.
look in the patch database for any others you havent already got installed or install the latest patch bundles.
If the drive is physically seen correctly like you say it is apart from the drivers side then youll probably find the answer is the patches. but as already said, dont be in a rush for your backups on that interface. (That was the downfall of the k classes in my opinion)
