C1537A External Tape druve

[Vincent_5]

Hi,
Can someone advice how I can I resolve this problem, I have install a HP-PB Single Ended / Parallel scsi card on a K260 Server. I'm trying to use this card to hook up to the C1537A tape drive. Steps that I have done :

In Kernel, I added driver SCSI1, Stape, Tape2, LPr2 and regen Kernel.

When run ioscan -kf , I found that the tape drive is not claim.

Class I Driver Description S/W stat H/W Stat
tape 1 stape ---------- unclaimed unknown

Model
C1537A

but, if I run ioscan -kfnC ext_bus
I can see the SE SCSI interface card.

Can someone please advice if a patch is needed or else how can I solve this problem. NOte: operating system is version 10.20

Please advice

Regards
Vincent

Hi Vincent,

What is the model of the interface card?
I have a K580 with a HP-PB card installed
model HP 28696A.
From my ioscan it appears as this.

ext_bus 10 10/4/4 scsi3 CLAIMED INTERFACE HP 2869
6A - Wide SCSI ID=7

If it the same card you may need 'scsi3'
driver installed into you kernel.

I assume you have installed the 28655A card correctly.
Do you have the driver named target in your kernel?
the correct chain of the drivers for thios card is:
Class ext_bus ->scsi1 -> target -> tape2


Hope that helps

Based on information that you provided, there is something wrong.
What you need is scsi1, tape2 driver in the kernel.

Class I Driver Description S/W stat H/W Stat
tape 1 stape ---------- unclaimed unknown

Driver should be tape2, not stape because stape is used in tape drives connected to HSC or GSC bus.
on tape devices attached to HP-PB single-ended adaptor, HPUX uses tape2.

Check out drivers, cables and terminator.

Hope this helps,

Hi,
Sorry, here are the additional info. The model of the card is 28655A and when I run ioscan it show

ext_bus 10 10/4/4.3 scsi1 claimed interface HP 28655A SE SCSI ID =7

As for the command ioscan -kf | more to search for tape device, it show

Class tape I 1 driver stape h/w path s/w interface unclaimed h/w interface unknown model C1537A

Please advice

Sounds like you need to add "target" to your kernel.

[Pierre BRUEL]

Tape2 is the correct driver for your tape drive.
I've experienced the same difficulties on a K380.
The solution i've found is to use SAM (Peripheral Devices/Tape Device/Add). Sam integrates in the kernel all that is necessary. Needs halt and reboot.
