Ultrium 230 not found on rp5400 HPUX11r2

[Kuang Chen]

Just connect the ultrium 230 to on rp5400 server. I tried insf -e and ioscan found the tape unknow.
> ioscan -fn
ext_bus 0 0/0/1/0 c8xx CLAIMED INTERFACE SCSI C896 Fast Wide LVD
target 4 0/0/1/0.3 tgt NO_HW DEVICE
unknown -1 0/0/1/0.3.0 NO_HW UNKNOWN HP Ultrium 1-SCSI

Is anyone know this issue?

Does the syslog.log or dmesg show that the h/w has been detected?

Has the Kernel got the driver for the stape?
lsdev is the command to check !!

UNKNOWN means no driver, but NO_HW means is no longer connected (but it was previously).

First make sure the drive is connected, SCSI ID is set (current value is 3 - make sure it is unique) and the bus is terminated. Configure the stape driver to the kernel.

did not see any stape.

vmunix: 0/0/1/0.3 tgt
vmunix: 0/0/1/1.7 tgt

You will have to add the stape driver to the Kernel and then udpate the kernel as your kernel is missing hte stape driver !!

ID3 is unique.
I checked couple time the connection. Not quick understand why ioscan -fn in description it found HP Ulltrium 1-SCSI, but Device unknown? Any tool to diagnose the tape driver?

[Torsten.]

again:

UNKNOWN means no driver, but

NO_HW

means is no longer connected (but it was previously).

Check the connectivity!
(cable, terminator, cross check the drive with another server just in case of a bad drive)

The device name came from the inquiry.

You need to add tape drivers to the kernel and reboot.

I would go ahead and add both stape and tape2 tape drivers. This can be done through SAM and SAM can rebuild the kernel for you.

Thanks Dhanish.
After dd stape to kernal, ioscan -fn find the tape
tape 0 0/0/1/0.3.0 stape CLAIMED DEVICE HP Ultrium 1-SCSI
