ioscan not detecting autoch (HP Autoloader 1/8 SDLT 320)

[Cara Tock]

Hello. I have installed an HP Autoloader 1/8 SDLT 320 hardware & attached it to a HPUX 11.00 server.

I have loaded the required drivers, per the HP web site, and rebooted the server. I still do not see the autoch (HP Autoloader 1/8 SDLT 320) drive when I do an ioscan.

Also, I tried using the LTT v3.5 tool to detect the hardware & the Autoloader shows up in the tool sometimes & then other times is absent. So, I cannot update the firmware for this Autoloader hardware either.

Please help.

Any additional advice?

[Sameer_Nirmal]

Well , couple of questions here
Which drivers you have loaded?
Which HBA you are using? ( PN and driver version )
What ioscan shows? ( Post ioscan -fn )

You should see an entry ( claimed ) for autoch with schgr driver for the loader besides entries for DLT drives with stape driver. You need to create a device file for loader using sctl driver.

Even though LTT supports this Autoloader , you need to make sure ioscan works correctly.


Note : You have given points to 32 out of 168 responses to you questions which is not good.

[Scott McIntosh_2 · Accepted solution]

Do you see the hardware device listed at all in an ioscan -fn? If LTT is sporadically finding it, you likely either have it moving between random and stacker modes (I assume this autoloader has such), a SCSI device conflict maybe, or hardware problems like terminators, cables, etc.

Cara,

My first guess would be that the schgr driver is not added to the kernel.

Can you post the output of 'ioscan -fnC autoch'?

All: Here is the posting of the "ioscan -fn" from the server that the HP Autochanger is attached to.

3. What ioscan shows? ( Post ioscan -fn )

You should see an entry ( claimed ) for autoch with schgr driver for the loader besides entries for DLT drives with stape driver. You need to create a device file for loader using sctl driver.

[Sameer_Nirmal]

Cara,

As per the ioscan -fn output , you see a SDLT 320 tape drive is conencted with SCSI ID 5. Did you set the SCSI ID for the autoloader? Ensure it is not conflicting with others.

The model should use two SCSI IDs , one for autoloader and anothere for the drive.

Refer the following document to get you an idea how it should be configured.

http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00411112/c00411
112.pdf

Set the SCSI ID ( un-used ) for the autoloader from the front panel. The procedure is given in the above document.
I guess you are already using SCSI IDs 0,2,5,7 . So you can use other remained IDs. But better you cross-check as you know the hardware better than us.
Once you are done with SCSI ID setting , you should see the autoch entry in the ioscan. Then run insf -e. It would create a device file with schgr as device driver. As I said before , you need to creat a new device file with sctl driver for the autoloder.

We are impressed from you comments about the forum and do appreciate it. The only thing to remind people over here about assigning points is to maintain the zeal of this forum forever.

Remember, you need to assign appropriate points to the responses based on how they are useful for you to know the soultion of the problem. If you assign points so freely which you did, would make the thread as answered/finished and people may not look at it assuming it is answered/solved already.

[Cara Tock]

Sameer -

Thank you for your reply. I have the doc from the link that you had posted. I agree; this is a very complete & helpful doc.

I did not set the SCSI ID for the autoloader. I didn't think that it was a requirement, however, I agree that I need to look into this more.

[Scott McIntosh_2]

The manual for the product notes that for the SDLT version of the product, the device uses two SCSI addresses, by default 5 for the drive and 0 for the robotics. Yet, you have a DDS drive at 0 already. Go into the autoloader front panel and change the SCSI address for the robotics to something unused, like 1 or 4, and reboot. Process is in the manual.

Ioscan is most useful when presented in fixed pitch font. As the forum input box uses, but not as displayed later. You should always put ioscan output in a plain text file and attach it rather than putting it in the text box.

Thanks,
Scott
